Direct3D multiple vertex buffers, non interleaved elements

I'm trying to create 2 vertex buffers, one that only stores positions and another that only stores colors. This is just an exercise from Frank Luna's book to become familiar with vertex description, layouts and buffer options. The problem is that I feel like I have made all the relevant...

CopyResource from one D3D11 device to another

I can copy the content from a D3D11 texture to another one with ID3D11DeviceContext::CopyResource. The method belongs to the immediate context of a specific device, so I cannot copy a texture from one device to another one (I have tried it - it explodes as expected saying "D3D11 CORRUPTION: ID3D11DeviceContext::CopyResource:...

D3D11 Post Shader Results in Dark Image

I'm trying to implement post shaders (pixel shaders) as a test. I have a texture to which all stuff is rendered, and the post shader simply copies this texture to the back buffer. If this texture is larger than the back buffer, the post shading process results in dimming: However,...

DirectX 9 not rendering after adding transforms

so far I got a cube rendered without any transforms (thus it was rendered in an orthographic perspective), and I am working on the previous code to get it into a perspective view, with all the matrices involved. I changed the Flexible Vertex Format so as not to have RHW...
