@eniko blue noise 😏

[eniko@mastodon.gamedev.place]

looks like fensters has bugs on windows, that's unfortunate

i managed to resolve the window size one via code from an open issue, but, don't think i can recommend this for windows sadly

@eniko can I just have CDE from my old SunOS sparcstation ? Does that make me old and archaic ?

[eniko@mastodon.gamedev.place]

heck yea! triangle!

[floby@mastodon.social]

@eniko best shape!

[devlin@topspicy.social]

@eniko this reminds me of an old tale about the playstation (1) devs getting excited over a triangle on screen. It was a moment of great importance

@eniko Vulkan "Eniko Edition" looks good so far!

debug rendering tiles that are skipped because they're known to be blank

[robloach@fosstodon.org]

@eniko Game Devs just want one thing and it's disgusting.

[eniko@mastodon.gamedev.place]

debug rendering tiles that are skipped (red) and tiles that can do a fast path (cyan) because they're known to be fully covered and fully within the viewport, so they can skip inside/outside and pixel clipping checks

[fabiosantoscode@mastodon.social]

@eniko is that larger phase a "coarse triangle rasterizer" part of the "fine triangle rasterizer"?

[eniko@mastodon.gamedev.place]

@fabiosantoscode sort of? i'm not actually splitting the triangle or anything

i step through the bounding box in 8x8 tiles and check the corners to see if all corners of the tile are either fully outside any given edge, in which case they're blank and i can skip the pixel by pixel rendering

and if all corners are inside the triangle (and the viewport) then i know i can do the fast path

then for each pixel in the 8x8 tile i plot the pixel if it's inside the triangle/viewport

@eniko it sounds like a great optimisation!
