Give it up to a minute to load. Use the WASDEQ/arrow keys to manipulate the camera. Use can use the "# triangles to draw" to show the order that triangles are sorted in.
This is an implementation of Tipsify in Scratch. The Tipsify sorting algorithm reorders the index buffer of a 3D mesh for vertex locality. Tipsify was created by Pedro V. Sander, Diego Nehab, and Joshua Barczak. This uses a Wavefront .obj loader written by @Vadik1. The vertex transformation matrix code was written by @TheGoodGuy8000. Tipsify is described here: https://gfx.cs.princeton.edu/gfx/pubs/Sander_2007_%3ETR/tipsy.pdf
