We don't use the "Effect" class in our engine instead we have some custome class to manage shader,parameter, render state,etc which is more flexible. So i have to manually parse the constant table. GetConstantByName() is exactly what i'm looking for. It's a little odd they provide a ShaderConstantTable but don't make it ...

Hi, I'm doing some shader constant parse work, is there any way to get the hlsl struct member without using effect framework? In native code, i can use ID3DXConstantTable::GetConstantByName() by setting the struct handle as first parameter.  However seems the Constants property of ShaderConstantTable only exposes top-level variable. Any help?

I was confused, the Windows API Code Pack comes out with a managed wrapper for DirectX10/11, does this mean mdx is coming back and xna will never get support to DX10/11? I know there are a lot difference between 9 and 10/11, but it seems odd to have two different set of managed api for DX. Besides, I've heard there many design issues in the ...

I'm totally agree with Michael, the new xna math lab seems so attractive. Any plan for the xna team to support this feature in managed code?

that's make perfect sense thanks shawn :)

Hi all I set a break point in the CustomModelProcessor.cs ProcessNode() method to see how data is organized between MeshContent,GeometryContent and VertexContent. To my understanding, MeshContent may have several GeometryContent children, but they all reference to the same vertex of MeshContent. GeometryContent and VertexNode have a ...

[quote user="shaKu"] 1) I would have to write this functionality into every shader so that I could project my decals onto every surface regardless of which shader it is using. 2) I am limited to as many textures as I code parameters into the shader and this is not the case in games such as world of warcraft. In this game it is common ...

Try to convert NURBS surface to polygon.

Break both background plane and texture into small pieces, and only render the visible part.
