A really simple single header Wavefront .obj loader with glut support.

Including:

// Only needed at first include#defineSIMPLE_OBJ_IMP// glut needs to be included first for drawObj implementation#include<GL/glut.h>#include"simple_obj.h"

Full docs:

Usage:

// Loading a .objSimpleObj_t*myObj=loadObj("some_model.obj");

Drawing:

// GL setup stuff, transforms, ect...drawObj(myObj);
// More GL stuff

Groups:

// Access the struct for the first group in the file.ObjGroup_t*group=objDataArrayAccess(&myObj->groups, 0);
// Attributes: name, startFace, endFace, & render.group->render= false; // don't draw this group.

Freeing obj data:

// This obj is trashdisposeObj(myObj);
// It's where it belongs now

Working:

• Vertices
• Normals
• Texture coords
• Faces
• Basic rendering

Todo:

• Separate group rendering (done)
• Materials
• Maybe support some more obj features
• Clean up and free stuff (done)
