2023 SL SUG meetings week #29 summary

Posted on by Inara Pey
Luane’s Magical World, May 2023 – blog post

The following notes were taken from the Tuesday, July 18th Simulator User Group (SUG) meeting. They form a summary of the items discussed and is not intended to be a full transcript. A video of the entire meeting is embedded at the end of the article for those wishing to review the meeting in full – my thanks to Pantera for recording it.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas.
  • These meetings are conducted (as a rule):
  • They are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Server Deployments

  • On Tuesday, July 18th, 2023, all simhosts on the the SLS Main channel were restarted without any deployment.
  • On Wednesday, July 19th, 2023, the BlueSteel RC channel should be updated with a new simulator version, comprising:
    • llGetPrimitiveParams will be able to identify animesh.
    •  The estate ban limit gets raised to 750, and the number of estate managers to 20 – however, a viewer-side update is required for these changes to be visible.
    • Two new LSL functions for LSD llLinksetDataDeleteFound and llLinksetDataCountFound.
    • Changes to UUID generation on certain items per my week 26 SUG meeting summary (e.g. textures, notecards, materials (particularly the upcoming PBR Materials)) to reduce the amount of duplication. These changes will not impact  UUIDs for objects rezzed in-world or made by the viewer.
    • Further work to correct some of the friends issues (as seen with BUG-232037 “Avatar Online / Offline Status Not Correctly Updating”). However, how effective these updates might be will not be fully understood until the update has been more widely tested through general use on Agni.

Viewer Updates

No updates at the start of the week, leaving the current official viewers in the pipeline as:

General Discussion

  • Core discussion points in the meeting:
    • [Video: 5:57 (start)] A general discussion on the new LSL / LSD functions and associated constants, which widens into a wider discussion on LSL / LSD.
    • [Video: 18:58 (start – overlapping with LSL / LSD discussion)] Discussion on larger regions vs. attempting to fix current region crossing issues. In short: larger regions would be a deep, fundamental change to SL (much of the simulator and viewer code is built on the assumption that regions are sized at 256x256m) which would likely not resolve the overall issue of region crossing events; ergo, the general consensus was towards trying to solve for crossing issues with the current region size. This led to a broader discussion on region sizing, user on-boarding, etc.
    • [Video: 21:22 (start – overlapping with the above)] Questions on throttling glTF overrides on animations (particularly in reference to puppetry).
  • In brief:
    • Confirmation that the ability to allow experiences to access the key-store from anywhere without land permission should be in the next simulator maintenance update.
    • The work to lighten the impact of avatars entering a region (in particular via teleport) impacting region / viewer responsiveness has yet to reach the main grid.

An Evergreen visit in Second Life

Posted on by Inara Pey
Evergreen, July 2023 – click any image for full size

Elyjia Baxton sent me an invitation to tour her latest region design which recently opened to the public, and given her past work – often featured in this blog – I was delighted to accept as soon as time allowed.

Evergreen is a Full private region leveraging the land capacity bonus, and held by Karo Camorra (abella74). It has been designed as a public space by Ely to provide, in Karo’s words, a place where people can:

Chat with your friends in the town overlooking the beach, or enjoy a solitary or romantic stroll in the forest or follow the path along the river while taking advantage of the various places to relax in a calm and lush setting, and take some photos.

– Karo Camorra (abella74)

Evergreen, July 2023

The town and beach in question lie to the north-east of the region, the landing point sitting at the top of steps connecting the former with the latter. Extending into the south-eastern quarter of the region, the town is a small, but distinctly European-looking affair, the tall houses  – some with ground level business – are all façades, rather than furnished buildings. However, it offers numerous little places to sit and pass the time, while the steps and path leading down to the beach run between saplings and shrubs before reaching the warm sand. This is guarded by a tall tall wooden watchtower / radio shack, now converted into another cosy hideaway, under which the path runs, but accessed directly from the beach.

The beach also offers various places to sit and pass the time as it runs along the north coast to arrive at stone steps rising to the western side of the main island, passing by way of a raised wooden deck where an artist appears to have taken up shop. The beach is given a sense of popularity courtesy of a schooner apparently passing by in full career just off-region, and two Linden Endurance-class sailing boats moored in the shallows.

Evergreen, July 2023

Prior to reaching the beach, the gravel path almost branches to the left, passing alongside a low wall separating the little town from the land flowing down to the sands. With birch trees lining one side of it and saplings  the other, the latter also providing some shade to the wild growth of flowers sitting between the path and the beach. Narrowing as it reaches the western side of the town, the path meanders its way west, passing by a summer house, a cylindrical folly and a gravel pool, all of which offer places to sit, with the latter linking to a path pointing back eastwards to a gazebo and chaise lounge sit among the wildflowers and overlooking the beach.

As it reaches the summerhouse and folly, the westward-pointing path splits, a rougher trail continuing west to offer the way up to the region’s lighthouse as well as the means to reach what had likely once been a north-western headland.

Evergreen, July 2023

Now separated from the rest of the land by a narrow channel, this former headland has the feel of having been long since deserted; Nature is in command, what had once been a brick-and-wood greenhouse sits abandoned to her claim. This may have once have been a base of operations for the artist who has taken over the wooden deck mentioned above; if so, then perhaps advancing years had caused the artist to foreshorten the walk from town to studio, leaving the latter to its fate in favour of using the deck for their artistic expression.

The path to the western isle also branches prior to reaching the channel separating the headland from the bulk of the region. Pointing south, this passes by a very modern-looking pavilion built over the west coast before branching yet again, one arm looping back to the summer house and folly, the other continuing on through the trees and plants to a little cove cuddling a secluded shack and its dock within its shallow arms, a home for moored rowing boats and deckside rocking chairs.

Evergreen, July 2023

Inland from this shack, the land is split by a stream which descends in a series of low falls from the uplands on which the town sits, to finally turn south and fall into a broad pool which does much to help form the landscape of southern half of the region. In doing so, the stream gives form to a tongue of land running east from the edge of town, caught between the stream to one side and the drop down to the waters below on the other. It is home to a steel-framed conservatory, home to tropical plants within an otherwise temperate setting.

With the waters of the pool and the streams flowing outward from it, the southern side of the region is perhaps the most photogenic. Once again, paths meander around it, starting with the one descending from the town to the south-east. Here, streams flowing out from the pool cut the land into slices and give rise to very natural lowlands which are in equal part rocky, rich in plant life and with plenty of places to sit and pass the time – as well is in which to take photos.

Evergreen, July 2023

The south-eastern corner of the region is dominated by a wooden windmill overlooking the south coast. It is reached via a gravel path which curves south and west from the foot of the steps descending from the town and carried over the gorge of a stream by a covered bridge. After passing the furnished windmill, this path continues onwards to offer the best route of southern exploration.

Following it will take visitors past a pier extending out into a shallow bay (and the home of table-top games which can also be reached from a teleport station near the region’s landing point), and by more places to sit – a riverside covered picnic spot, another folly and an old bandstand – to cross another small stream before curling itself around the large pool mentioned above. It ends in at a little cottage on the east coast.

Evergreen, July 2023

All of which is a long-winded way of saying this is a region worthy of seeing first-hand; there is a lot to see and appreciate – more so than I’ve presented in the last 1,000+ words. Offered under a fairly neutral selection of environmental settings, Evergreen naturally lends itself to a broad range of EEP settings, with opportunities for photography large and small throughout.

Finished with a matching natural soundscape and given a sense of age through the scattered ruins and derelict building awaiting discovery and live via the presence of wild and domestic animal and the furnished cottages and cabins, Evergreen makes for a thoroughly engaging visit.

2023 SL Puppetry project week #28 summary

Posted on by Inara Pey
Puppetry demonstration via Linden Lab – see below.  Demos video with the LL comment “We have some basic things working with a webcam and Second Life but there’s more to do before it’s as animated as we want.”

The following notes have been taken from chat logs and audio recording of the Thursday, July 13th, 2023 Puppetry Project meetings. Notes in these summaries are not intended to be a full transcript of every meeting, but to highlight project progress / major topics of discussion.

Project Overview

General Project Description as Originally Conceived

LL’s renewed interest in puppetry was primarily instigated by Philip joining LL as official advisor, and so it really was about streaming mocap. That is what Philip was interested in and why we started looking at it again. However since Puppetry’s announcement what I’ve been hearing from many SL Residents is: what they really want from “puppetry” is more physicality of the avatar in-world: picking up objects, holding hands, higher fidelity collisions. 
As a result, that is what I’ve been contemplating: how to improve the control and physicality of the avatar. Can that be the new improved direction of the Puppetry project? How to do it?

– Leviathan Linden

  • The project is rooted in the in idea of “avatar expressiveness”, referenced in a February 2022 Lab Gab session with Philip Rosedale and Brad Oberwager and officially introduced as Puppetry in August 2022 to provide a means by which avatars can mimic physical world actions by their owners (e.g. head, hand, arm movements) through tools such as a webcam and using technologies like inverse kinematics (IK) and the  LLSD Event API Plug-in (LEAP) system.
  • Since that time the project has expanded in size, attempting to encompass improving SL’s (somewhat primitive) IK system; investigating and developing ideas for direct avatar-to-avatar, avatar-to-object interactions (“picking up” an apple; high-fives. etc.); providing enhanced LSL integration for animation control; broader hardware support; adoption of better animation standards, etc.
  • This has led to a change in approach for the project – see below for more.

Bugs, Feature Requests and Code Submissions

  • For those experimenting with Puppetry, Jiras (bug reports / fixes or feature requests) should be filed with “[Puppetry]” at the start of the Jira title.
  • There is also a public facing Kanban board with public issues.
  • Those wishing to submit code (plug-ins or other) or who wish to offer a specific feature that might be used with Puppetry should:

Resources

Change In Approach

  • The Puppetry User Group meetings have, until now, been held on Aditi (the Beta grid) at the Castelet Puppetry Theatre, commencing at 13:00 SLT, and generally on alternate Thursdays to the Content Creation meetings, and as per the Second Life Public Calendar.
  • As of the July 13th, 2023 these meetings have now been suspended until further notice.
  • This does not mean the project is being abandoned; it was noted during the meeting that as several of those involved in the project attend other User Group (SUG) meetings – notably, but not exclusively, the Tuesday Simulator User Group meeting -, discussions on Puppetry can continue within hose meetings.
  • Explaining the decision, Simon Linden Noted:
There’s definitely a lot of interested tech and possible features with [Puppetry]. [However] the original idea of doing real-time mocap on webcams was like opening Pandora’s box in terms of features and ideas, and also was a lot harder than we expected … in the end I think it’s better to work on some fundamental tech that can be used in a lot of other ways – like IK, streaming, figuring out how animation data can work with scripts, solving some challenges like just doing a decent hand-shake.

– Simon Linden, July 13th, 2023

  • Elements of Puppetry which have thus far been confirmed as continuing as WIP projects comprised (but are not necessarily limited to):
    • The real time animation streaming component of Puppetry (forming something of a hybrid between the LEAP <-> viewer work already undertaken, and Leviathan Linden’s work in streaming animation playback from one viewer, through the simulator and to other viewers without any direct interaction with the animations by the simulator).
    • IK Improvements and updates (see below).
    • Improved animation import support (see below).
  • There are also broader discussions going on in the Lab regarding possible further overhaul of the animation system.
  • The above decision re: Puppetry meetings being the case, this will be the last of these my dedicated Puppetry Puppetry summaries for the time being, but I will continue to report on Puppetry / related work as and when it is discussed at other meetings such as SUG meetings and Content Creation User Group meetings.

Meeting Notes

Animation Import

  • One of the Puppetry expansions, improving / broadening animation import into Second Life was spun-off into its own project and June.
  • Notably with this work, LL is using Assimp (github: https://github.com/assimp/assimp), which supports some 30-40 animation formats (including the likes of .FBX and glTF), converting them to its own format for ease of import to multiple platforms.
  • The work is now in its own branch of the official viewer (DRTVWR-584, not currently ready for public consumption in any way).
  • This viewer uses the Assimp engine to read animation files, and the viewer extracts data from there for preview and then uploading as a SL animation. Animation imports it supports include:
    • BVH files, as per the current animation import within the viewer.
    • FBX format files.
    • Animations saved with the Mixamo skeleton, as supported by other tools.
  • The Mixamo element of the viewer is currently incomplete, but there is a focus on getting it wrapped up so the viewer can enter the project viewer pipeline at some point for public testing. However, when complete, it is hoped that importing an animation with a Mixamo skeleton from the likes of  Blender or a tool like Rokoko Studio should work fairly seamlessly.
  • To help with imports, Aura Linden has included an option on import to scale motion, which might be further automated slightly, for improved ease-of-use among less experienced content creators.
    • If this process is automated, it will include an capability for manual override of course for those who are more experienced with animation creation and import.

Inverse Kinetics  (IK) Updates

  • Leviathan Linden’s IK work has pretty much become a mini-project in its own right.
  • Most recently, he has been focused on implementing Forward And Backward Reaching Inverse Kinematics (FABRIK) – which is the fundamental algorithm for suggesting new joint positions in a range of applications, including 3D modelling.
  • This work has been in part a matter of trial-and-error, and most recently, Leviathan has been fixing issues of where constraints are enforced in FABRIK which impact the SL avatar, although he still has some more constraints to fix.
  • Fixing these issues has required additional visualisation / debugging tools, which he’s having to code for himself.

Additional Notes

  • A further request was made for updating the bento reference skeletons on the wiki, which are reported as being “broken”, per BUG-10981 “Test content for public Project Bento Testing wiki page” and this Content Creation Discord channel discussion. This will be chased internally at LL to see if action is being taken.

Asian Cinema in Second Life Art

Posted on by Inara Pey
Kiku Art Gallery: Daikota Wind – 18 Images Inspired by Asian Films

I was drawn to the boutique-style Kiku Art Gallery, operated and curated by Rafael Nightshade and Suzanne Logan – who also operates the Amatsu Shima estate within which the gallery is located – for an engaging and fun exhibition with combines Second Life photography with another visual medium: Asian Cinema.

Occupying the South room of the gallery, is 18 Images Inspired by Asian Films by Daikota Wind, which also carries this shorter title Asian Cinema. As both titles suggest, the focus of the exhibition is on cinematic productions of the Far East, which film-making is (as if it needs saying) as rich and genre-spanning as cinema in the west (or anywhere else in the world).

Kiku Art Gallery: Daikota Wind – 18 Images Inspired by Asian Films

When considering Asian cinema, thoughts are likely to focus on the likes of Chinese (/Hong Kong) and Japanese productions which have a long history of western exposure (and inevitable re-makes / re-interpretations), together with – more recently – that of South Korea. Due to the prolific output of these three powerhouses, they do dominate this exhibition, although Indonesia and Thailand also get very honourable mentions. However, rather than focusing on national output, this exhibition seeks to offer insight into the aforementioned genre-spanning nature of Asian film-making.

To achieve this, Daikota presents 18 images of films ranging from action to thriller, passing by way of comedy, drama, fantasy, post-apocalyptic, romance and more, each image inspired either by a scene from the film it represents or from the posters used to advertise it. Each image shares its space with a brief synopsis of the film’s storyline.

Kiku Art Gallery: Daikota Wind – 18 Images Inspired by Asian Films

The images themselves appear to have been subjected to minimal post-processing, adding to their connection with the film they represent, rather than suggesting how the artists interprets the film. The accompanying text offers a fair description of each film’s plot, together with some insights by Daikota giving each one more of a personal feel.

Some of the films – Infernal Affairs, Crouching Tiger, Hidden Dragon, Ju-On, to name three, but Daikota’s images and synopses give them a freshness and vitality which certainly increases the desire to go and watch them. Light and engaging, 18 Images Inspired by Asian Films offers a worthwhile exploration of Daikota’s photography and the films of the far east.

A summer in The Shambles in Second Life

Posted on by Inara Pey
The Shambles, July 2023 – click any image for full size

I last visited The Shambles when it occupied a Homestead region and presented a steampunk-come-sci-fi theme (see: In The Shambles in Second Life). But that was a year ago (or, when put in purely Second Life terms – a decade ago!). A lot has happened in that time. For one thing, Tolia Crisp has relocated The Shambles to a Full private region; for another she has once again teamed with Dandy Warhlol (Terry Fotherington) to offer another engaging and photogenic region under the Frogmore banner.

At the time of my visit, The Shambles was open to members of the Frogmore group, who are also invited to participate in a landscape photo competition with a L$8,500 prize pool, including L$5,000 to the outright winner (+a 4-week free stay at Frogmore Cottage). Details on this competition are available through the Frogmore group, and it will remain available for entry by group members until August 4th, 2023. However, The Shambles itself will open to full public access on Saturday, July 15th, 2023, and will remain so through until Tolia closes it for a Halloween redressing – so this might be considered a little advanced promotion for the region.

The Shambles, July 2023

Those who have visited the core Frogmore regions will find much that is familiar within this iteration of The Shambles. It offers something of a continuation of the rugged coastal environment that mixes touches of England’s Cornwall and Devon with a stirring of European coastal areas, bound together with a touch of summer days perhaps made more bearable by the cooling influence of an light breeze drifting in from over the sea.

This is not to say that The Shambles doesn’t have its own personality or independent looks – it most certainly does. In fact, the overall styling contains more of a lean towards parts of Europe’s multi-faceted coastlines than it does the UK’s, and there is, as ever, plenty to see and discover whilst exploring.

To the west, the land is low-lying and formed by a deep inlet / bay complete with a broad sandy beach to one side, facing an headland which rises as a broad shoulder of rock protecting the inlet from the wilder elements, capped by a small fishing wharf suitable for trawlers at the head of the bay. This sits as one of two guardians watching over the entrance to the bay, the other being the (inevitable? – We SLers do so love them…) lighthouse.

A broad cobbled street parallels the beach, offering multiple points of interest whilst aged steps climb the eastern uplands as they rise to a roughly flat top before falling away sharply to the seas below again.

This highland area is home of a variety of locations, each one with its own charm and beauty. There’s the dirt track running past stables, the horses from which graze both in the field alongside it and the meadow above from which rises the head of a tumbling stream which steps its way down along the east side of the setting before using a waterfall to jump down to the sea on the north side.

The Shambles, July 2023

Or – and keeping to the north side of the region – there’s the campsite with its mix of caravans and tents. It’s a cramped but clearly popular location, although how the caravans got up there is a nice little enigma. Certainly, the same track as runs past the stables was used for the final leg of their journey, but its southern end ends in a rocky drop descended only by more aged stone steps and by more water tumbling from a small pair of pools.

Watched over by a tall bell tower, the southern end of the island seems to exude a sense of age, a careworn spit of land splitting the waters between open sea and narrow channel. Another fishing wharf sits on the narrow spit, itself crossed at several points by a variety of bridges, whilst its eastern end is guarded by two lighthouses, one of considerable age, the other perhaps one of the more recent structures on the island.

The Shambles, July 2023

All of which is just the start of a description for what is a genuinely captivating setting, rich in content, with many places to sit and pass the time or enjoy a drink or two. There’s also a bungee jump for the more adventurous, although this may be absent whilst the photo competition is running. As one would expect from the pairing or Tolia and Terry, there is a deep since of natural beauty throughout; a feeling that – as is the case in the physical world – the land was present long before people arrived, the wind, fresh water, sea and rain forming it into folds and turns, high points and lowlands, slopes and drops, humans have in turn used to their advanced in establishing a lasting presence here.

Needless to say, the entire setting is highly photogenic and those of the Frogmore group wishing to enter the competition should find lots here by which to create an entry, whilst those wishing to take avatar-centric photos which are not for the competition but purely for pleasure, can also join the Frogmore group for rezzing rights with props.

The Shambles, July 2023

Again, the region will be open to the general public from Saturday, July 15th, 2023, but those wishing earlier access can – again – join the Frogmore group. Enjoy.
