Like z, a primitive whose vertices are all beyond the same x or y plane (|x| > w) isn't drawn, for every primitive type and with clipping on or off; a vertex on the plane is inside (gpu/probe exp176, gpu/clipping/xycull). Immediate-mode vertices carry screen coordinates in their clip position, so only z culls them. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
