Dolphin removing the unwanted from your view

Update 16th March: features from this Viewer have been attributed as coming from NACL, which is apparently incorrect. As information is taken at source, I’ve now removed references from the article below. It is also reported that the Sound Explorer and Asset Blacklist may have licencing issues – see Comments.

dolphin-logoLance Corrimal is working steadily on Dolphin, with roughly a release every couple of weeks of late, providing plenty of new features and tweaks to the V3.2-based Viewer.

The latest release, offers potentially improved graphics handling for older / lower-specification graphics systems (with the exception of ATi systems) and provides blacklisting capabilities for those who are repeatedly troubled by unwanted sights / sounds or need to find an elusive sound.

Texture Compression

For graphics cards with 512Mb or less of memory, Dolphin will have texture compression enabled by default. This should help prevent such systems crashing when running SL. The option can be manually enabled / disabled via PREFERENCES->GRAPHICS->HARDWARE SETTINGS.

Lance advises that users with ATi graphics cards should avoid using the option, and keep it switched off.

Asset Blacklisting and Sound Explorer

The Asset Blacklist is a means of removing unwanted objects, textures or sculpt maps from your world-view. Sounds can also be blacklisted via the Sound Explorer (described below).

The Asset Blacklist operates in a similar manner to derendering an item, but with the advantages that a) items that are blacklisted remain so until de-listed, so that if you teleport away from a location and return, you do not need to de-render them again; b) the asset blacklist can be shared by accounts using the same Viewer; c) you can even share lists with other users – hand if you are running a Group or similar and your base of operations is blighted in some way.

Problems with things regularly ruining your personal world-view?
Add them to your Asset Blacklist
And enjoy the view

Items are added to the list by asset type – object, texture, sculpt map – and recorded by UUID to prevent a simple renaming of the object causing it to reappear.

Blacklisted items are managed via the Asset Blacklist floater (WORLD->ASSET BLACKLIST).

The Asset Blacklist floater and key buttons

The Sound Explorer allows you to list all sound sources operating around you. It is accessed via WORLD->SOUND EXPLORER. This enables you to filter the available sounds by type, listen to them individually, identify their location and, if required, add them to your Asset Blacklist.

Sound Explorer: locate, listen-to or even blacklist sounds in your location by type

Both of these make extremely useful additions to the Viewer, and will likely prove very useful for those who routinely visit places where there may be issues with items or sounds impacting personal enjoyment.

Other Nips and Tucks

  • Anti-spam also arrives in Dolphin with this release (ME->PREFERENCES->DOLPHIN 3-> ANTI-SPAM
  • Help has been extensively overhauled within this release of Dolphin so that all help buttons in the Viewer now redirect to the Dolphin Viewer forum
  • The “Items incoming too fast” pop-up behaviour has been changed so that it is no longer necessary to click OK in order to remove the message – it will now fade-out on its own (something I hope all other TPVs will adopt; the message is annoying in its default behaviour)
  • Anti-aliasing is no longer off by default as it doesn’t impact overall performance so much as it once did
  • Fly-after-teleport has been fixed within the Viewer so that if you were flying prior to a teleport, you’ll still be flying on arrival
  • There have been some performance tweaks.


This release has some nice additions for those that suffer visual / audio blights around their home space in-world. While the “performance tweaks” aren’t specified in the Dolphin blog, while running this release I did obtain a very small improvement of my average fps rates  (around 3-4fps), with this release averaging around 41fps at 390 metres, and 23fps on the ground compared with the last release of Dolphin I actively tried ( With shadows enabled, this drops-off to around 12fps at 390 metres and 10fps on the ground (all checks with 3 other avatars on-sim)..

I also recently used Dolphin on Kitely, where it also worked flawlessly, making it my 2nd choice of Viewer for visiting other VWs, after Exodus.

  1. It’s been popular lately for viewers to not look too closely at where their code is actually coming from. These new features don’t come from NaCL.

    Sound Explorer originates from Emerald/Phoenix and has incompatible licensing with all viewers derived from LL’s snowstorm. In technical terms Sound Explorer can only be included with V3 code if the V3 code was relicensedunder the pure GPL without exceptions, but licensing under the pure GPL (no exceptions) would cause other critical viewer components to become license violations.

    Similarly, the asset blacklist comes from Emerald/Phoenix and has the same licensing problems.

    There’s a reason why these features haven’t been picked up in more mainstream viewers based on LL V3. People know how useful and important the features are. However, the licensing doesn’t work out. They need to be partly rewritten to be kosher.


    1. Arrehn, thanks for this.. It’s the second time I’ve been caught with incorrect attributions.

      It also highlights the problem bloggers have when trying to ensure attributions *are* supplied (as some developers demand) – were we to try to follow up on every feature included in a Viewer, articles wouldn’t get written.

      Will revised & update.


  2. Thank you for the tip; this viewer has resolved three major visual polution issues that have been plaguing me recently.


  3. Here is an excellent test case for the new TPV rules. Does derendering the red cube in your illustration effect the “shared experience”? How about if it was a tree or a house much closer?
    If it does not, and the code is avaialble with only license problems; given it’s obvious appeal the the resident community, will LL move to incorporate it into the default viewer so all viewers can use it?


    1. I’d have thought it was outside of the shared experience, inasmuch as it is not impacting what other people see or impacting the world in general; it’s you your choice – and theirs – as to whether an item is derendered (as is the derender common to TPVs).

      As to the rest… can’t say. Maybe Oz will drop by and comment :).
