What does compute shader mean in Direct3D 11?
A compute shader is a programmable shader stage that expands Microsoft Direct3D 11 beyond graphics programming. The compute shader technology is also known as the DirectCompute technology.
Which is unordered access view in compute shader?
Only RWStructuredBuffer s and RWByteAddressBuffer s are available as unordered-access views. A thread can only access its own region in groupshared memory for writing, though it can read from any location. SV_GroupIndex or SV_GroupThreadID must be used when accessing groupshared memory for writing. Groupshared memory is limited to 16KB per group.
Can a compute shader run on many threads?
A compute shader can run on many threads in parallel. A compute shader on Microsoft Direct3D 10 is also known as DirectCompute 4.x. If you use the Direct3D 11 API and updated drivers, feature level 10 and 10.1 Direct3D hardware can optionally support a limited form of DirectCompute that uses the cs_4_0 and cs_4_1 profiles.
How does a compute shader work in OpenGL?
OpenGL calls this the globalwork group. This will be i.e. the total dimensions of a 2d image to write. We later define how to sub-divide this into smaller groups of jobs – localwork groups. You write a compute shader to process any one job within a work group. i.e. colour one pixel.
What kind of Technology is a compute shader?
The compute shader technology is also known as the DirectCompute technology. Like other programmable shaders (vertex and geometry shaders for example), a compute shader is designed and implemented with HLSL but that is just about where the similarity ends.
How is compute shader similar to vertex shader?
Like other programmable shaders (vertex and geometry shaders for example), a compute shader is designed and implemented with HLSL but that is just about where the similarity ends. A compute shader provides high-speed general purpose computing and takes advantage of the large numbers of parallel processors on the graphics processing unit (GPU).
