occlusion

Should an object in a 3D-engine use different bounding volumes for collision-detection (broad-phase) and culling?

Basically class renderBounds and class physBounds versus class boundingVolume?

Each of this classes then could either contain the same type of volumes (AABB's, kDOP's, sphere's etc.) or a special fitting one for the particular object.

(note: without considering of using an external physics engine)

I'm working on a 2D game in which I would like to do collision detection between a moving circle and some kind of static curves (maybe Bezier curves). Currently my game features only straight lines as the static geometry and I'm doing the collision detection by calculating the distance from the circle… >>> More

Unity Occlusion Portals: What and How?

as seen on Game Development - Search for 'Game Development'
(Here I eat my words on Meta about posting Unity questions on Unity Answers... since that site is less responsive than this one.) Unity provides cell-based Occlusion Culling (via Umbra, I believe).

Ambient occlusion shader just shows models as all white

Okay so I have this shader for ambient occlusion. It loads to world correctly, but it just shows all the models as being white. I do not know why. I am just running the shader while the model is rendering, is that correct? or do I need to make a render target or something? If so then how? I'm using… >>> More

In "modern" environments, the "NV Occlusion Query" extension provide a method to get the number of fragments which passed the depth test.

Problem Imagine that we have a 2D uniform grid of dimensions N x N.
