python script to convert .OBJ files into Minecraft, rendering them in game with a core shader.

vertex id

Minecraft's gl_VertexID isn't per model, so it's difficult to find the relative id of a vertex in a model unless you have a constant number of vertices

i thought up a trick to assign each face a unique pixel uv, then encoding the offset of the pixel from top left (relative 0,0 in the texture, some random place in the atlas)

with the offset data i am able to calculate the relative face id, and gl_VertexID % 4 gives the corner.

Python

i learned Python just to write this lol

apparantly anything that has to do with js can't keep rgb values correctly when alpha isnt max
