The first parameter is the number of viewports being used, and the second parameter is the a list of pointers to the viewport structs. The range will correspond to the D3D11_VIEWPORT you set, possibly something along the lines of: D3D11_VIEWPORT viewport = {0}; viewport. If the number of viewports (in the variable to which pNumViewports points) is greater than the actual number of viewports currently bound, unused elements of the array contain 0. Before we create our depth/stencil buffer, we need to define it. The pixel shader must produce a float4 result marked as SV_Target.

I'm pretty sure it will hold a reference to the backbuffer texture and lead to a memory leak. The viewport defines an additional transformation that occurs before rasterization: Direct3D uses the viewport location and dimensions to scale the vertices to fit a rendered scene into the appropriate location on the target surface. h> #include <d3dx9core. MinDepth = 0. We use the view port in a call to ID3D11DeviceContext::RSSetViewports to bind the view port to the rasterizer stage of the pipeline. The projection transformation converts vertices into the coordinate system used for the viewport. That's because NDC is the same in GL/D3D, but tex-coords are flipped. I'm guessing your constant buffer isn't being properly referenced by your shader. h. To make it dynamic we set Usage to D3D11_USAGE_DYNAMIC and CPUAccessFlags to D3D11_CPU_ACCESS_WRITE in the description.
