How do I fill in 3D Triangles? Do not give me a link to a faster triangle filler (I already know), and dont tell me to map it into 3D. My main question is: How do I turn in those 2D points to 3D? I am using @MathMathMath ‘s 3D tutorial!

Note: i want to learn how to map the points with @DadofMrLog ’s triangle filler.

Ok, here’s how most 3d engines work:

You have a bunch of coordinates with x, y, and z values.

Implement rotation with the x, y, and z axis.

Apply some perspective.

Fill in polygons (triangles usually) using those points.

This is just a rough outline. Khan Academy has a good page explaining how all this works though.

Still kinda necroposting again, but seriously, thanks for your help :P

I suggest checking out @Scratch-Minion and his 3D projects studio.
