#SL Land Impact Update Week 19

by

1

Since my last update on Land Impact Costs changing there has been a decision on how the Lindens will handle sculpties.  In the recent Pathfinding (PF) User Group (PFUG) meeting Falcon Linden reminded us of the new equation for figuring Land Impact Cost.

As Falcon put it, “…sculpts will be capped at 2.0 streaming cost, not 1.0. (Note, that’s a CAP, so if they were less than 2.0 in new accounting before, they’ll still be less than 2.0).”

Ardy Lay asked, “What was jacking up the streaming cost?”

Falcon’s response, “It wasn’t a bug, it was just a formula that, upon further consideration, we decided was not appropriate, i.e., when it was first implemented, it was actually calculating a triangle-based render weight, which for meshes is a good measure of streaming cost, but not for prims.”

Yuzuru Jewell asked, “Is the new cost applied to all the objects?”

#SL Mesh Defomer at Risk

by

17

Scanning the Second Life® news today I found an article on new World Notes by Hamlet about Oz Linden reconsidering whether the Mesh Defmer is worth the effort… the bother to add it to Second Life. Hamlet’s article is: Linden Lab Needs Mesh Samples to Test Qarl’s Mesh Deformer — Or May Not Incorporate It Into SL Viewers At All.

If you don’t know the Mesh Deformer or the Parametric Deformer is the missing part of the mesh project that was never completed. The Deformer will allow mesh clothes to change with avatar shape controls. It causes mesh clothes to follow the Enhanced Avatar Physics, the clothes bounce with the boobies. The Lindens are considering dropping the project. We need to demonstrate support for the project for it to continue. This article is about getting the support into a visible place for the Lindens to see.

I found Oz’s comments in the JIRA STORM-1716 item. Continue reading →

#SL Viewer with Mesh Deformer

by

2

RL work has kept me away from Second Life®. Lot’s is going on with SL Viewers and the Mesh Deformer. I’m having to catch up today, Sunday. Inara Pey got the basic information out Friday the 4th in Mesh Deformer update: release from Qarl, request from Oz.

Project Viewer

The Mesh Deformer has its own Linden Lab® project viewer. There have only been two releases of it, AFAIK. The previous one was in January as a version 3.2.6 (247240). The current one is 3.3.1 (255595). I’m not clear on the development trunk; I think it changed to Oz-Porject-2. Whatever, you can get a copy of the viewer here: Second Life Deformer Project Viewer Download. You’ll also find I have added the link to the blog roll on the left.

Mesh Deformer Control in LL Project Viewer

The current stable viewer for Second Life is version: 3.3.1 (254524). So, the versions are close cousins. The current SL Development Viewer is at version: 3.3.3 (255744). Without digging through the repository and figuring out which branches are merged in when, I can’t know which fixes and changes are in which viewer version. But, the 3.3.1’a I’ve been using tend to crash on exit.

#SecondLife Land Impact Costs to Change

by

9

Friday Falcon Linden made a late appearance at the Sever/Scripting User Group meeting. He announced with the coming of Pathfinding we will see a change in the costs associated with Land Impact. In no small part the change is being influenced by PATHBUG-69.

The Brain behind Torley?

PATHBUG-69 – llVolumeDetect(TRUE) is broken. According to the wiki:

If detect is TRUE, VolumeDetect is enabled, physical object and avatars can pass through the object. This works much like Phantom, but unlike Phantom, VolumeDetect objects trigger collision_start and  collision_end events when interpenetrating. Collision events will trigger in any script in the object.

#SL Deformer Update Wk17

Qarl Fizz change his code posting and the missing parts are up. So, presumably Third Party Viewers have the code and are able to compile viewers with the feature.

Henri Beauchamp’s Cool VL is likely going to see a new version release today.

@Qarl

New patch ported to the Cool VL Viewer and working fine (a new release including it will likely be published tomorrow or the day after).

The issue with “jumping meshes” (see my comment for v0.2) is yet still not solved (but I implemented a work around for it in the Cool VL Viewer, that at least doesn’t trigger the “jumping mesh” issue with avatars not wearing deformed meshes).

I was unsure what Henri meant by ‘jumping mesh.’ I have seen mesh winking in and out of existence using Niran’s viewer… whatever, reading the referenced comment:

#SL Mesh Deformer 0.3 Released

by

3

This morning on qLab, Qarl Fizz’s blog, I see Qarl has released a new version of the Mesh Deformer. He writes:

quick announcement – i’m releasing version 0.3 of the deformer code. primary changes: 1) should now apply cleanly to recent linden viewer code, 2) deformation tables are computed in the background on another thread, so no frame stalls.

enjoy.

Henri Beauchamp 4.25.12 / 12am

Err… Qarl… lldeformerworker.h and lldeformerworker.cpp are missing from your patch !

I think we will see this version come out in a Linden Lab® project viewer as the previous version did not play well with the 3.3.0 viewers. It also handles the problem I ran into: having to wait for about a minute to see the Deformer kick in.

#SL Scripting and Mesh News Wk17

by

Not much going on in scripting right now. Various changes and new functions are winding their way through QA and the release channels. But, not much new information. Also, Kelly Linden did not have the usual Scripting User Group Meeting this Monday.

Prep Linden at Content/Mesh Meeting

The new PRIM_SLICE in llSetPrimativeParams() is in testing on Magnum Release Channel. The Magnum release is having problems with group chat. So, it is unclear whether that feature will roll to the main channel tomorrow or not. I can’t image that llSetPrimativeParams() is causing group chat issues. But, the Lindens are testing interactions, so it may not make it.
