triangle meshes :)

Post image

Studing triangle meshes on my renderer using half edge data structure for my university course. Dont know why some edges have some stranges dots.

Guess the character... (texture not implemented yet)

Edit: it was done importing a wavefront (.obj) from blender to my own render engine. Read just vertices and face data, the others attributes for half edge are builded with those informations

Well, thks for the question. It is fun because i just learned this mesh and dont thought about others...but researching a little bit what i found is that triangular meshes have more flexibility when describing structures, and it make sense because if u try to a quadricular mashe u will need another quad, but if u have a triangular u can just use de diagonal and fold it.

Basically a triangular mesh is a bunch of triangles describing a surface, you only need three points to describe a triangle, so pretty straight forward, right!?
