Rasterize Triangle in 2d & 3d
Hi,

Is there an easy way in EE to rasterize between three vertexes in a 3d grid (voxel), and separately three vertexes in a 2d grid (picture)?

Else should I look about doing this manually, bounding boxes and clipping, etc?

Thanks,
Chris

there's no builtin function

there's only EdgeWalker for 2D (it's somehow related)

Ah, I saw that but couldn't extend it to 3d easily. I'm wondering if I can use Vec Lerp, but just use Int's and set the step as 1/Dist(intEdge1, intEdge2) or something similar (haven't thought it through yet)... perform the Lerp across one edge of the triangle, then as you start lerping on the next edge, also lerp back to the first edge to cover across the middle of the triangle.
