Why are quads preferred over triangles?

Support Basics & Interface

Hello World,

I have been studying a bit about the decimate modifier, and the tutorial says it reduces things to triangles before setting them back to quads. But I never completely understood what was so bad about triangles.

Any insights appreciated!

  • Tris are bad for subsurfing.
  • Quads make a better base mesh for sculpting (partly because of (1)).
  • Quad meshes have well-defined edgeloops.
  • Quad meshes deform more controllably (partly because of (3)).

Best wishes,
Matthew

That makes a lot of sense, but I would probably order it 3, 4, 1, 2 because it seems to be the edgeloop that is key to the deformation and subsurfing.

A second question seems to follow from the first, which is - when is it okay to use triangles?

Hmmm… Ty for the input.
