GL_NUMWORKGROUPS(3G)

✨ NAME ✨

okay so this is the GL_NUMWORKGROUPS(3G) page, and it's literally about gl_NumWorkGroups — the header's middle slot is [FIXME: manual], which is giving placeholder main-character energy, but the actual thing we're talking about is gl_NumWorkGroups, and it contains the number of workgroups that have been dispatched to a compute shader. That's the whole vibe. 💅

🎀 DECLARATION 🎀

bestie, the declaration is short, and the original has the .SH "DESCRIPTION" bit glued right onto it, so we're keeping that exact little chaos goblin:

in uvec3 gl_NumWorkGroups ;.SH "DESCRIPTION"

🌈 DESCRIPTION 🌈

In the compute language, gl_NumWorkGroups contains the total number of work groups that will execute the compute shader. The components of gl_NumWorkGroups are equal to the num_groups_x, num_groups_y, and num_groups_z parameters passed to the glDispatchCompute command. That's it — no extra lore, just the group-count trio. 🫶
