#SL Animation Changes

In January of this year Laurent Bechir filed a user story in the SL JIRA, STORM-1803. The JIRA item points to Machinimatrix’s post on Second Life’s animation format. The animation format controls what we can upload into SL. In a way this user story is a feature request.

Oddly it is the Biovision Hierarchy (BVH) file format used for uploading that restricts much of what we can do with animations in Second Life. Internally SL uses an .anim type file format that allows more animation controls than BVH.

Some of the things an ANIM file allows are:

  • Different animation priorities per-joint
  • Keyframed animation control of eyes!
  • Variable length joint offsets per frame (allowing cartoon-like “stretchy” bones)
  • Keyframed rotation and repositioning of attachments (which meshes can weight to; to use as new child bones  )
  • Client Side scaling of attachments and default mesh
  • ANIM files are text files

#SL Problems Today

by

Seems one of the data centers went down. That took the Market Place, is rumored to have knocked 10k users offline, cutoff access to ADITI, and generally borked things. Rod has been tweeting about it. Rod started tweeting about 11:30 AM, if my math is right, which is several hours after the problem event started. … Read more

#SL Content/Mesh News Week 7

by

In the Content and Mesh User Group some interesting things came up today.

Transparent Mesh

If a mesh object is transparent should that change its Land Impact cost? Should it even render? If it doesn’t render, doesn’t it use fewer resources? It seems the Lindens are looking at this special case and considering how to implement such a change.

Content-Mesh Meeting

Runitai says the code to NOT render 100% transparent objects is in the pipeline. The release of the code has been delayed because it broke highlight transparent. (SH-2963)

Dropping Mesh Things

If you have a mesh attachment, you cannot drop it as you would a prim or sculpty attachment. Mesh objects rigged or not, detach back into inventory.

#SL Mesh Deformer Update

by

Qarl put out new Mesh Deformer code yesterday (2/13) about 3 PM. This release should handle the crumpling problem better. We will know as soon as someone gets the code into a viewer where we can use it. To see the crumpling problem see: #SL Bare Feet.

#SL Scripting News Week 7

by

The big news this week was Tiggs’ announcement about Linden Realms’ Tools. I cover that in: #SL Linden Realm Tools. Otherwise, there was little news in the scripting area.

New Functions

For some time we have had the improved List Functions bouncing in and out of the release channels. It looks like they will make it to the main grid this week. For the past week the server maintenance package including them has been running on all 3 release channels. So, it should be well tested. Keep your fingers crossed.

These are the improvements to speed up Linden Scripting Language (LSL) functions that handle lists. Look back through the articles in Scripting News for a list of them.

#SL Linden Realm Tools

by

This morning Tiggs Linden visited Kelly Linden’s Scripting User Group to talk about Linden Realm Tools and made some announcements. Charlar Linden pointed out that none of the information is cast in stone, so things may change.

Tiggs Linden and a smokey pipe

Tiggs made it clear we are only getting part of the story for now by saying there are two things Tiggs would be discussing, a third Tiggs would be hinted at, and a fourth component of which no mention would be made.

Two Tools

The first two things are new scripting functions; llTeleportAgent() and llAttachToAvatarTemp().

Tiggs is opening up llTeleportAgent() to allow the same access as llTeleportAgentHome(). This means the object running a script with this command must be owned by the parcel/land owner.
