Objtri
I've recently had a need for testing graphics stuff on arbitrary models which I tried to solve by grabbing random free OBJ models off the net. Unfortunately, most of these models are made of quads and I need triangles. This small and naive utility triangulates the models.
There's nothing fancy applied to the model. No optimizations, no geometry modifications.
Usage
Input is path to an .obj file, e.g. "C:/folder/model.obj". Output will be "C:/folder/tri_model.obj".
