Support for `.mtl` Files with Textures #6924

Open SableRaf opened 3 months ago

Increasing access

This enhancement would make it easier for people to use pre-made 3D models within their p5.js projects. It would broaden the creative possibilities for artists and designers by enabling more detailed and textured 3D models within p5.js projects.

Most appropriate sub-area of p5.js?

Feature enhancement details

Since version 1.9.2, p5.js supports .mtl files, but only for vertex colors (see processing/p5.js#6710).

This request aims to extend that support to include textures loaded by an .mtl file. Implementing this feature would involve creating a new data structure capable of handling both 3D models and their associated textures, potentially multiple per model.
