I've read many times that triangles should be avoided in meshes, too give one reference: "Introducing Character Animation with Blender by Tony Mullen" says that equilateral triangles work fine as long you don't deform them. It seems to be common in game development that the models are triangulated.

• What issues are introduced by using triangles?
• Does the same apply for n-gons?
