GLDISPATCHCOMPUTE(3G) [FIXME: manual] GLDISPATCHCOMPUTE(3G)

glDispatchCompute - launch one or more compute work groups

void glDispatchCompute(GLuint num_groups_x, GLuint num_groups_y, GLuint num_groups_z);

num_groups_x

The number of work groups to be launched in the X dimension.

num_groups_y

The number of work groups to be launched in the Y dimension.

num_groups_z

The number of work groups to be launched in the Z dimension.

glDispatchCompute launches one or more compute work groups. Each work group is processed by the active program object for the compute shader stage. While the individual shader invocations within a work group are executed as a unit, work groups are executed completely independently and in unspecified order. num_groups_x, num_groups_y and num_groups_z specify the number of local work groups that will be dispatched in the X, Y and Z dimensions, respectively.

GL_INVALID_OPERATION is generated if there is no active program for the compute shader stage.

GL_INVALID_VALUE is generated if any of num_groups_x, num_groups_y, or num_groups_z is greater than or equal to the maximum work-group count for the corresponding dimension.
