Viewer release summary 2012: week 38

This summary is published every Monday and is a list of SL viewer / client releases (official and TPV) made during the previous week. When reading it, please note:

  • It is based on my Viewer Round-up Page, a list of  all Second Life viewers and clients that are in popular use (and of which I am aware) and which are recognised as being in adherence with the TPV Policy
  • By its nature, this summary will always be in arrears
  • The Viewer Round-up Page is updated as soon as I’m aware of any releases / changes to viewers & clients, and should be referred to for more up-to-date information as the week progresses
  • The Viewer Round-up Page also includes comprehensive links to download pages, blog notes, release notes, etc., as well as links to any / all reviews of specific viewers / clients made within this blog.

Pathfinding: summary update

Linden Lab has been quietly working on pathfinding, clearing a range of bugs, updating the supporting documentation (some of which is still a work-in-progress) and providing more information for users aimed at clearing up misconceptions / misunderstandings. The following is a quick update on recent activities.

Lorca Linden’s FAQ

On September 18th, Lorca Linden posted a Pathfinding FAQ to the Second Life Server branch of the technology forum. While perhaps not the most high profile place in which to post the information, the FAQ nevertheless addresses a number of core issues related to pathfinding and makes a valuable read for anyone interested in using pathfinding or who wishes to understand more about pathfinding in general, rather than relying on hearsay.

One of the major misconceptions which is perhaps missing from the FAQ is that disabling pathfinding in a region will somehow “improve performance”.  In fact,m the only thing disabling pathfinding for a region does is to prevent pathfinding characters from operating; the underpinning Havok engine remains unchanged, and no Havok functionality related specifically to pathfinding is “turned off” in any way. So if there are no pathfinding characters being used within a region, disabling pathfinding will not improve the region’s performance, and any apparent improvement which may be noted is more than likely a placebo effect.

Pathfinding Tools In The Viewer

The latest release version of the SL viewer (3.3.4.264911) now includes the pathfinding tools, as do a number of TPVs, some of which I reported upon a while back, and which have since been joined by Firestorm (4.2.2.29837+); while Singularity (1.7.1+) also now provides some of the viewer-side tools / options associated with pathfinding.

Documentation-wise, work has been put in on cleaning up the existing wiki pages (although some are still somewhat out-of-date or difficult to follow as they presume a certain level of understanding). An updated list of pathfinding wiki documentation and related resources which I’ve previously published in the blog can be found in Related Links, below.

While there is still ongoing work in relation to a number of pathfinding bugs, the arrival of the pathfinding tools into the SL release viewer theoretically marks the point at which pathfinding might be considered “fully released” (as previously indicated by Lorca Linden). As such, it would be beneficial for Linden Lab to provide a formal blog post on the subject, including links to relevant resources such as those listed below in order to make the information more readily apparent to SL users, regardless as to how well (or otherwise) LL believe their blog is read.
