In Topic: view frustum culling particle effects?

Check each point and grab the min/max, center is (min + max) * 0.5

Better yet approximate size so you don't need to recalculate every frame.

In Topic: Surface to texture

Use CreateTexture to create new texture then use GetSurfaceLvl to grab its surface then use UpdateSurface to copy to it from your surface,  tho i don't understand why do you even load surface from file instead texture?

Maybe he wants to copy some surface to new texture?

In Topic: Should I try to optimise the World matrix build like this?

I don't even use scaling (i don't need it at runtime for my project), as for translation and rotation i just compose into one matrix from vector and quaternion, and this is done only for "dynamic" objects since i have lot of static objects (where world is identity) so i can skip lots of unnecessary world*view*proj (so i have just one view*proj for all of those).

In Topic: Raycasting

What is the problem? You have many examples within their sdk.


Main part is :

    btCollisionWorld::ClosestRayResultCallback result(from, to);
    physicsWorld->rayTest( from, to, result );
... //  use result here
