I suddenly have the feeling that I have absolutely no idea how to implement invisible objects/bones.

Right now, I use hardware instancing to store the world matrix of every bone in a vertex buffer, and then send them all to the pipeline. But when dealing with frustrum culling, or having them set to invisible by my simulation for other reasons, means that some of them will be randomly invisible.

Does this mean I effectively need to re-fill the buffer from scratch every frame with only the visible unit's matrices? This seems to me like it would involve a lot of wasted bandwidth.

I need higher precision on a few values within my vertex and pixel shaders...I'm currently using floats, so I would like to use doubles...I've read that HLSL Model 4 has two functions to convert a double into two unsigned integers and back again( asuint() and asdouble() ). These functions are only… >>> More

What I am planning to do is have the models (or maybe just an identifier for the model to be used) stored outside of the directX9 framework, and so in nature have completely dynamic rendering.

I was wondering if anyone could elaborate any further on something that's been bugging me. In DirectX9 the main supported back buffer formats were D3DFMT_X8R8B8G8 and D3DFMT_A8R8G8B8 (Both being BGRA in layout). http://msdn.microsoft.com/en-us/library/windows/desktop/bb174314(v=vs.85).aspx With… >>> More
