llRegionSay(), and Modern Convenience

Wednesday, May 16th, 2007

So, at last, it appears that someone has cracked the 100m barrier! Apparently there is a new technology, soon to be available, which allows an object to speak clearly — without even shouting — and be heard anywhere in a Sim.
Oh, progress is a wonderful thing, but I cannot help but feel a bit of […]

More Sculpts!

Monday, May 14th, 2007

So attempted to create some sculpt textures using this maya plugin, and it seemed to do quite well- though i found out a couple of things- that UVs, when flipped, result in inside-out prims, and that having holes in your mesh makes your neat roach abdomen…

will turn into a roachy sphere when approached at close […]

LSL Listener Lag?

Tuesday, January 2nd, 2007

It seems to be “common knowledge” that “listeners cause lag”. That is, you’re “supposed” to avoid having too many open listeners, especially on channel zero. (A listener is any script which can respond to spoken chat commands.)
Just to put things into perspective I’ll quote an offhand remark of Philip Rosedale’s when asked, Does such and […]

Theory of the ShoutMesh

Wednesday, December 20th, 2006

This monograph shall explain the principles and implementation of ShoutMesh, a communications grid used to control theatrical lighting across a 12-sim continent. It may be of interest to those contemplating a similar endeavor.
The task was to control the various lighting and other devices for a live performance. These devices were from several vendors, but all […]

the Hunting of the Goo

Monday, October 9th, 2006

Recently there has been a spate of “grey goo” attacks in the SL world, and after reading these descriptions of the attacks, i have only one question: what does the “grey goo” look like? Can it be seen? Or does the server wink out before its discovered? Wikipedia notes that the terminology is older than […]

Trouble with White Crystals

Sunday, June 25th, 2006

As Horg Neurocam and myself are ironing out the minor engineering details of our Cavorite Flotation Device, we have come across one or two amusing “artifacts” if you will of the techniques.
To be sure, there is no cause for alarm. When the Cavorite Flotation Device is made available for purchase, you, dear customer, may rest […]

Stanford Team Investigates The Mines

Monday, June 19th, 2006

Stanford’s Life Squared blog had a brief mention of the Cavorite Mines which Horg Neurocam and I have been gradually restoring. It is gratifying and frankly reinvigorating to know that our efforts have begun to make accessible to men of science some of the relics and beauty of the old mines.

Dress Like A Scientist

Saturday, June 10th, 2006

I’m not very good at shopping. I try to go out and look at stuff, but I get easily overloaded… These all look the same, but for slight differences. Which do I like best? Is this a good price? What if I don’t like it? And I can’t find what I really wanted anyway. I […]

llMoveToTarget Experiments

Sunday, January 29th, 2006

llMoveToTarget(vector target, float tau)
I took some measurements of the rate of llMoveToTarget().
Experimental Setup:
I ran tests with mass ranging from 0.16 to 80 essellograms. For each mass, I initiated a 10 meter upward vertical movement with tau = 1. To sample at various times along the trajectory, the following code was used:
