Volume of the clipped shapes

03 August 2013 - 06:48 AM

Now i'm working on implementing buoyancy in my engine and having an issue with determining underwater volume for body collision shapes. I need to find volume of primitives such as sphere, capsule, cone and box clipped by a plane. I can't derive formulas myself so i'm looking for ready-made ones if they're even exsist. I tried google it first, but it doesn't provided me with satisfying results.

Thanks for help.


Frustum from modelViewProjection matrix?

12 January 2013 - 04:20 AM

See title. Is this even possible and how if so?

When i say "Frustum" i do not mean plane representation. I want to get something like this

 

float left,right,top.bottom,near,far;

Vector3 origin;

Quaternion rotation;

bool parallel;


DXT mipmaps

So here's the question: is that even possible to generate mip levels for DXT compressed texture without unpacking whole image?
