Functions
void	GPU_compute_dispatch (blender::gpu::Shader *shader, uint groups_x_len, uint groups_y_len, uint groups_z_len, const blender::gpu::shader::SpecializationConstants *constants_state=nullptr)

Detailed Description

GPU Compute Pipeline

Allows to dispatch compute shader tasks on the GPU. Every dispatch is sent to the active GPUContext.

Function Documentation

GPU_compute_dispatch()

void GPU_compute_dispatch	(	blender::gpu::Shader *	shader,
		uint	groups_x_len,
		uint	groups_y_len,
		uint	groups_z_len,
		const blender::gpu::shader::SpecializationConstants *	constants_state = nullptr )

Dispatch a compute shader task. The number of work groups (aka thread groups) is bounded by GPU_max_work_group_count() which might be different in each of the 3 dimensions.
