How to send multiple textures to shader-stack?
This desc struct is the one that gets passed to ID3D11Device::CreateTexture2D. Then in your shader you use a 3rd texcoord sampling index which indicates which 2D texture in the array you are referring to.
How does the vertex shader work in Direct3D?
Just as with the constant buffer, the vertex shader has a corresponding buffer definition for incoming vertex elements. (That’s why we provided a reference to the vertex shader resource when creating the input layout – Direct3D validates the per-vertex data layout with the shader’s input struct.)
How to assign constant buffers to shader registers?
For example, the HLSL for a pixel shader might take a texture and a sampler as input with a declaration like this. It’s up to you to assign constant buffers to registers—when you set up the pipeline, you attach a constant buffer to the same slot you assigned it to in the HLSL file.
What are the input and output types of a shader?
Shaders take input types and return output types from their main functions upon execution. For the vertex shader defined in the previous section, the input type was the VS_INPUT structure, and we defined a matching input layout and C++ struct.
Can you run pixel shader and compute shader at the same time?
For Pixel/Compute shader sync, you can’t run a pixel shader and a compute shader at the same time on the same device, so when your draw calls are finished, the textures are ready to use in compute for dispatch.

How to rebind multiple textures in id3dx11?
If you are using the effects framework you can use ID3DX11EffectShaderResourceVariable::SetResource, or alternatively rebind a new texture using PSSetShaderResources. However, if you are trying to blend between multiple textures, then you should use texture arrays.
How to interpolate between 2D and 3D textures?
You may also want to look into 3D textures, which provide a natural way to interpolate between adjacent textures in the array (whereas 2D arrays are automatically clamped to the nearest integer) via the 3rd element in the texcoord. See the HLSL sample remarks.
What’s the best way to blend multiple textures?
However, if you are trying to blend between multiple textures, then you should use texture arrays. You may also want to look into 3D textures, which provide a natural way to interpolate between adjacent textures in the array (whereas 2D arrays are automatically clamped to the nearest integer) via the 3rd element in the texcoord.
How is the texture array set before rendering?
Here is where the texture array is set before rendering. The PSSetShaderResources function is used to set the texture array. The first parameter is where to start in the array. The second parameter is how many textures are in the array that is being passed in. And the third parameter is a pointer to the texture array.
