TL;DR

Learn to import and interact with 3D models in p5.js using obj files.

Transcript

hello here we are in this video I'm going to attempt to take this three-dimensional toy train and put it into my computer somehow not really and the topic here is that I want to this is in my WebGL 3d p5.js serious I want to look at load model so what if I had a file on my computer that had all the geometry for a train in it or anything else so you...
