warning:
Ruins 1.5 only support 4G memory Max and float precision!
next version i will increase double precison!

Mesh triangle face had better not exceed 10000 !The best control within 2000
tri face; if you have 1G memory and above, you can setting debirs : 1024!
IF you want to shatter 10000 tri face, you must be at least :
sizeof(float4)*10000*3*512= 234.375M*3 and more, too large!! Be careful!!!

If out of memory, you can receive "CUDA Error: Out of memory!" in Maya script!



debris : debris number, the more quantity, the faster.

density: if you display card have 1G memory and above, you can setting value to 1 or 2;
if you set to 1, debris max 216, if you set to 2, debris max 64.
noise: debirs noise .


memory: if you receive a warning: "Please increase memory!" you need to modify value!
Because cuda Memory is very nervous! so can't to use large memory first!
The more debris, less memory!

preview: open debris and to observe.

retrun : return to initial position.
