Sascha Willems's personal blog at saschawillems.de covers programming and games. Since 2015, 6 different Hacker News readers have linked it 6 times. It is still writing: the last post was on 2026-10-17, and you can follow it by feed.
Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN readers link Sascha Willems's pages on his glCapsViewer OpenGL hardware capability tool and on GPU rendering. The comments discuss GPU triangle rendering and the tool's claims without judging the writing.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
What Hacker News says?
Rendering only one large triangle can be faster than two. First one triangle needs less memory, less vertex processing, etc. Second, modern GPUs render pixels in groups of 2x2 up to 8x8 "tiles". If only one pixel from this group is part of a triangle, the entire group will be rendered. When two triangles form a quad, the entire area along the diagonal "seam" will be rendered twice. The smaller quads you have, the mo…

HN discussionSo, educate me. https://www.saschawillems.de/creations/opengl-hardware-capab... claims: “The “OpenGL hardware capability viewer” (short “glCapsViewer) a multi-platform client-side application that reads out all important hardware capabilities of the current OpenGL-implementation present on your system” Reading its source ( https://github.com/SaschaWillems/glCapsViewer/blob/85ee6ab68... ), I get the impression it doe…
