NAME¶
gl_WorkGroupSize - contains the size of the workgroup operated on by a compute
shader
DECLARATION¶
const uvec3 gl_WorkGroupSize ;.SH "DESCRIPTION"
In the compute language,
gl_WorkGroupSize contains the size of a
workgroup declared by a compute shader. The size of the work group in the X,
Y, and Z dimensions is stored in the x, y, and z components of
gl_WorkGroupSize. The values stored in
gl_WorkGroupSize match
those specified in the required
local_size_x,
local_size_y, and
local_size_z layout qualifiers for the current shader. This value is
constant so that it can be used to size arrays of memory that can be shared
within the local work group.
