What does the depth buffer do in DirectX 11?
In DirectX 11 the depth buffer (also called the Z buffer) is primarily used for recording the depth of every pixel inside the viewing frustum. When more than one pixel take up the same location the depth values are then used to determine which pixel to keep.
Do you need matrix buffer for depth shader?
The depth vertex shader only requires the matrix buffer, no other globals are needed. For input into the vertex shader we only require position. Texturing, normals, and anything else is not required since we are only planning to color pixels based on depth.
When to use a depth buffer in Photoshop?
When more than one pixel take up the same location the depth values are then used to determine which pixel to keep. However usage of the depth buffer is very flexible and it can be used to do many different things.
What is the format of the depth buffer?
If you look at the D3DClass::Initialize function you will see we set the depth buffer format to DXGI_FORMAT_D24_UNORM_S8_UINT. What this means is that we use the depth buffer as both a depth buffer and a stencil buffer, and the format of the buffer is set to 24 bits for the depth channel and 8 bits for the stencil channel.
Where do I find the start buffer in Direct3D 11?
StartIndexLocation – specifies the first index buffer element from the base address and the offset provided in IASetIndexBuffer. The start location is supplied to the ID3D11DeviceContext::DrawIndexed or ID3D11DeviceContext::DrawIndexedInstanced method and represents the first index to render.
How to enable or disable depth stencil in Win32?
DepthEnable and StencilEnable enable (and disable) depth and stencil testing. Set DepthEnable to FALSE to disable depth testing and prevent writing to the depth buffer.
How does depth stencil work in Direct3D 11?
An array of render-target views may be passed into ID3D11DeviceContext::OMSetRenderTargets, however all of those render-target views will correspond to a single depth stencil view. The render target array in Direct3D 11 is a feature that enables an application to render onto multiple render targets simultaneously at the primitive level.
