GL_WORKGROUPSIZE(3G)

💖 NAME 💖

okay so bestie, this is the GL_WORKGROUPSIZE(3G) page — manual name 3G — and the header slot is literally [FIXME: manual] (placeholder era, no cap 💅). gl_WorkGroupSize contains the size of the workgroup operated on by a compute shader. Periodt.

🎀 DECLARATION 🎀

const uvec3 gl_WorkGroupSize ;

tiny source tea: the raw line also has .SH "DESCRIPTION" glued right after it — that's the manpage DESCRIPTION heading doing a little formatting glitch, we move on 🫶.

✨ 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. iconic constant behavior, honestly.
