Detailed Description

A triangle defined by three vertex indices.

A Triangle does not store actual 3D positions. Instead it stores three indices (v0, v1, v2) into a Mesh::vertices array. This is the standard "indexed face set" representation used throughout computer graphics: vertices are stored once and triangles reference them.

How it works (indexed face set): // Imagine a mesh with 4 vertices:

mesh.vertices = { vA, vB, vC, vD };

mesh.triangles = {

{0, 1, 2}, // first triangle: vertices[0], vertices[1], vertices[2]

{1, 2, 3} // second triangle: vertices[1], vertices[2], vertices[3]

};
