Node that defines a compute shader.
This node defines a compute shader, a shader stage used entirely for computing arbitrary information.
To store the result of the computation, an SoComputeShader may use SoShaderParameterImage or SoShaderParameterBufferObject with SoShaderParameterBufferObject::SHADER_STORAGE_BUFFER buffer type.
To fetch data, an SoComputeShader may use the above-mentioned parameter types, or regular texture access.
See SoShaderProgram for general information about using shaders and shader parameters.
See parent class SoShaderObject for details about using the inherited fields.
See SoComputeShaderScheduler for information about compute shader invocation.
