Hi again, im here for help...

Does anybody know a quick trifill method? i know @electricgryphon had one somewhere but i didnt find any info about it. i have a simple 3d draft thing with vertecies and lines, but im yet to make it colored, i cant figure out how to, really(no tris no fill, mfw). If anyone knows and can explain, please, do.

Also i wander, ZEP's 3d dots demo uses weak persp projection, right? do... all 3d softwares use weak projection? is there any difference between regular one? is this even a thing? i heard it being mentioned in one of 3d tutorials and i cant really get what it means(ortho projection with depth- whaaaa isnt it just regular persp projection????)

thanks beforehand, just want you guys to know that i love this little community!!!

You might want to check out my renderer? It's not without bugs (running out of memory) but it works aside from that. Don't ask me anything about perspective projection though, I got my dad to explain it to me lol.

Here are the trifill codes by option.

If you want to understand how it works, it is a good idea to try making the following code.

  • Sort three points by Y coordinate
  • Process to fill triangles with a "horizontal bottom"
  • Process to fill triangles with a "horizontal top"
  • Process to divide three random points into the above triangles

I think you should definitely use those trifills instead of mine lol
