I have more and more GUI in the tool! a new #demomaker is slowly shaping out from this development.

Dự án tinyrenderer phiên bản thứ hai: dựng hình phần mềm chỉ với 500 dòng code C++! 💻 Tuyệt vời cho những ai muốn tìm hiểu sâu hơn về graphics pipeline.

Wrote some more about extending the "HAKMEM 149 line algorithm" to a quad rasterizer to be able to draw billboards (sprites) up to 3D sprites, the HAKMEM approach (and forward mapping) lose a bit of interest when degrees of freedom (and projection) are added up though but it was fun to retrace the sprites history a bit.

#computergraphics #softwarerendering #algorithm

A tiny way to compute a square / triangle wave at the same time without conditionals, only basic arithmetic and shifts.

This can be used for #oscillators or animations etc. #algorithm is a variant of HAKMEM 149.

Can also be used to draw a square. (And other shapes, see previous toot)

Code also shows how to draw a diamond shape by rotating the square by 45°.

There are two versions, optimized for size and optimized for speed.

#computergraphics #p5js #softwarerendering #codegolf #sizecoding

A tiny way to draw an "isometric" (dimetric) cube in an iterative fashion with a single loop, all integers with an integer variant of HAKMEM 149 (so called Minsky circle) display hack. (Sin / Cos approximation)

Can also be used to draw a hexagon (it is a filled hexagon after all) and can easily render fractured cubes as well by varying "l" (second screenshot)

I've been writing some software rendering code, and one of the benchmarks I wrote produced some nice looking output! The most recent feature I implemented was MSAA for so the triangles could be anti-aliased.

okay, now it's good enough.

Tutorial now updated to work with the latest sdl3:

also includes a bunch of fixes and cleanups. A lot of new stuff coming as soonish. (Should I add fedi comments to these pages?)

This is pretty cool.
