What is depth stencil state?

What is depth stencil state?

A depth and stencil state object that specifies the depth and stencil configuration and operations used in a render pass.

What is the function of stencil buffer?

In the simplest case, the stencil buffer is used to limit the area of rendering (stenciling). More advanced usage of the stencil buffer makes use of the strong connection between the Z-buffer and the stencil buffer in the rendering pipeline.

What is stencil OpenGL?

Advanced-OpenGL/Stencil-testing. A stencil buffer (usually) contains 8 bits per stencil value that amounts to a total of 256 different stencil values per pixel. We can set these stencil values to values of our liking and we can discard or keep fragments whenever a particular fragment has a certain stencil value.

How to create depth stencil DESC in D3D11?

Pass a pointer to D3D11_DEPTH_STENCIL_DESC to the ID3D11Device::CreateDepthStencilState method to create the depth-stencil state object. Depth-stencil state controls how depth-stencil testing is performed by the output-merger stage.

How to configure depth stencil functionality-win32 apps?

In the second render pass the ID3D11DeviceContext::OMSetRenderTargets function is used to set the depth-stencil view to NULL or a different depth-stencil resource and the shader resource view is passed to the shader using ID3D11EffectShaderResourceVariable::SetResource.

How does a shader read a depth stencil buffer?

An inactive depth-stencil buffer can be read by a shader as a texture. An application that reads a depth-stencil buffer as a texture renders in two passes, the first pass writes to the depth-stencil buffer and the second pass reads from the buffer.

What does the state of depth stencil mean?

The depth-stencil state tells the output-merger stage how to perform the depth-stencil test. The depth-stencil test determines whether or not a given pixel should be drawn.
