I have a question ablout use shadowmap to implement visible function.How to choose a appropriate size for shadowmap?

I want to use shadowmap to do visible determinate,the other patchs with the shoot patch. It is the same as your mention.:-)

This Demo is compute radiosity in GPU.version 0.0015 The algorithms is: Use three 32bit fp texture store the patchs's attribute. Texture1: B,DeltaB,patch id,DeltaB*area Texture2: pos,area Texture3: normal,ref first,init the three textures. while (need iterative loop) {...

Is that you made reference Local PRT? I don't understand the means of the convolution coefficients in Loacl PRT.

I have a idea about use SH Lighting and PRT in Key Frame Motion.Compute the PRT of the vertex per-key frame,then blend dot(SH Lighting,the PRT of the first key frame) and dot(SH Lighting,the PRT of the second key frame). But used this method,the disadvantage is more storage requirements.

In XBOX,use XGSetVertexBufferHeader to set Texture as Vertex Buffer. Use this method,you can render to vertex buffer(use the same data with the texture).

Your means that the R9700 disable the z-optimizations (early z reject, hierarchical z) when doing depth-fail rendering?

cache or mem?

The z-cache only store the z info. The effect of the z-cache should be only in z-clear and z-test. Why improved Z-Cache can optimize stencil-buffer operation?

How many bytes in the Z-Cache?

http://www.tomshardware.com/graphic/20030306/radeon9800pro-03.html "The optimizations in HyperZ III+ mostly affect the improved Z-Cache, which is now more flexible and was optimized for stencil-buffer data. " What is the Z-Cache? Thanks.

"This means you "merge" a multisample surface (depth/stencil) with a non multisample surface (texture) " Why did you merge the depth/stencil buffer with the render target ? I think the object of the "merge" should been the first render target and the second render target.

Your means is render the thermal object uses 2 sequential dependant textures fetches ?

I have a mistake. :cry: :cry: :cry: It is a night vision,not a infrared thermal.
