| ==Rotating 360 degrees NonPhys==
| |
| Awhile ago I stumbled upon [[Slerp]], and I wanted to make a way to generate a list of rotations for doing a complete rotation.
| |
|
| |
|
| (this is some of the UGLIEST code I have ever written, but it seems to work. Do not rely on it if you need precision.)
| |
| <lsl>
| |
| list GenerateRotationList(integer num)
| |
| {
| |
| list RotationList = [];
| |
| rotation a = ZERO_ROTATION;
| |
| rotation b = llEuler2Rot(<0,0,180> * DEG_TO_RAD );
| |
| float interval = 2 / (float) num;
| |
| float i = interval;
| |
| for(; i <= 1; i += interval)
| |
| RotationList += slerp(a,b,i);
| |
|
| |
| if(num % 2)
| |
| i = 1 - i + interval;
| |
| else
| |
| i = interval;
| |
| b = llEuler2Rot(<0,0,180.001> * DEG_TO_RAD );
| |
| for(; i <= 1; i += interval)
| |
| RotationList += slerp(b,a,i);
| |
| return RotationList;
| |
| }
| |
| </lsl>

| ==SLURL Raster Image URL Generator==
| |
| I was rather interested in the raster images provided within SL and SLURL.com so I decided to figure out how to replicate it in such a way that it could be incorporated into tools and/or services outside the standard fair offered by Linden Labs. At some point I may rewrite it to use PHP or offer tips to incorporate it into something like the WMS provider in MapGuide.
