Python ComputeShader

The main idea is to simpify the process of coding a compute shader in OpenGL for python This module has no ability to handle image2D, Uniform Buffers, etc...<br> The idea is to fill an SSBO with data, run a compute shader on it, then read the SSBO's content.<br> One can use multiple buffers for the communication, there is no optimization possibilities yet for read-only and write-only buffers.<br>

Requirements

<br> <br> <br> <br>

Common

Info()
StartTimer()
GetTimer()

Info returns a python dict filled with glGet<br>

• GL_MAX_COMPUTE_SHADER_STORAGE_BLOCKS<br>
• GL_MAX_SHADER_STORAGE_BUFFER_BINDINGS<br>
• GL_MAX_COMPUTE_SHARED_MEMORY_SIZE<br>
• GL_MAX_COMPUTE_ATOMIC_COUNTERS<br>
• GL_MAX_COMPUTE_WORK_GROUP_INVOCATIONS<br>
• GL_MAX_COMPUTE_WORK_GROUP_COUNT<br>
• GL_MAX_COMPUTE_WORK_GROUP_SIZE<br>
• GL_MAX_UNIFORM_BLOCK_SIZE<br>
• GL_MAX_COMPUTE_UNIFORM_BLOCKS<br>
• GL_MAX_COMPUTE_UNIFORM_COMPONENTS<br>
• GL_MAJOR_VERSION<br>
• GL_MINOR_VERSION<br>

GetTimer returns a float in seconds<br>

Compute Shader (CS)

NewCS(source)
UseCS(cs, x, y, z)
DeleteCS(cs)

NewCS returns a new compute shader compiled from the source<br> rest of the functions return None<br>

Shader Storage Buffer Object (SSBO)

NewSSBO(content)
UseSSBO(ssbo, cs, binding)
UpdateSSBO(ssbo, data, offset)
ReadSSBO(ssbo, size, offset)
DeleteSSBO(ssbo)

NewSSBO returns a new compute shader initialized with the content<br> ReadSSBO returns the value read from the GPU starting at the offset<br> rest of the functions return None<br>

Optional parameters

NewCS(source)
UseCS(cs, [x = 1, y = 1, z = 1])
DeleteCS(cs)
NewSSBO(content)
UseSSBO(ssbo, cs, [binding = 0])
UpdateSSBO(ssbo, data, [offset = 0])
ReadSSBO(ssbo, size, [offset = 0])
DeleteSSBO(ssbo)

Exceptions

There is a poor implementation for exceptions inside the module but they are hard to catch since the 32 and 64 bit version of this module has it's own Exception
