added texturing to my affine triangle rasterizer

[purplejillybeans@kind.social]

@eniko Whenever I hear the term "affine" my mind goes straight to the PSX. Going for that sort of aesthetic?

@eniko Eniko is making either Quake or Heretic and I'm all for it 😤

(even if it's neither, I'm still all and still for it 😤😤)

[cloudthethings@hachyderm.io]

@eniko lookin a-mighty affine

[eniko@mastodon.gamedev.place]

@PurpleJillybeans i mean, it'll be similar due to being affine, but this will have subpixel precision so it won't be as wobbly

mostly affine is just way faster/easier >_>

@eniko nice!

[eniko@mastodon.gamedev.place]

@foone look ma, no gap pixels!

[ddr@pony.social]

@eniko Ooh, very nice!

[captainarcee@retro-gaiden.com]

@eniko so smooth! Mode 7 on the SNES got nothing on this

@eniko @foone Hey! My grandpappy Playstation fought and died in the Early 3D Wars so you could make that joke!

making a triangle rasterizer is a lot like programming language development. you make a few building blocks and then you're like "theoretically, using this, i could make *anything*"

@eniko rasterizer for anything makes one feel powerful. this mouse made one for arbitrary flat n-gons for fun once and even though it had terribly hacky math for the projection it was still a powerful feeling

[yon@sakurajima.moe]

@eniko Are triangles the equivalent to s expressions in programming?

(And how did I not know they are abbreviated sexp, that’s crazy.)

[aeva@mastodon.gamedev.place]

@eniko that is a fine triangle rasterizer you've got there

[halcy@icosahedron.website]

@eniko skulls just feel *right* for this type thing, huh

[ronflaix@mastodon.gamedev.place]

@eniko daaamn, magic

[fabiosantoscode@mastodon.social]

@eniko truly a fine rasterizer

[eniko@mastodon.gamedev.place]

and now its gouraud shaded *and* textured

also it makes me happy when people tell me it's a fine triangle rasterizer because that's the name of the library :3 so thank you to everyone that did so

[halcy@icosahedron.website]

@eniko everything in place to pull out env map reflections as a fun party trick

[eniko@mastodon.gamedev.place]

@halcy would you believe i have plans >_>

[eniko@mastodon.gamedev.place]

should i do the psx colored texturing thing where medium gray is treated as 1 and white is treated as 2? in other words instead of mapping rgb 0-255 to 0-1 it treats it as 0-2, so values over 128 make the texture channels brighter, while under 128 make it darker (and 128 stays the same)
