Robust Wavefront OBJ model parsing in C

Article presents a robust Wavefront OBJ parser in C, detailing challenges and techniques in parsing 3D model data, showcasing a technique to handle undefined behavior, and demonstrating the parsing process with sample code.

• Wavefront OBJ is a 3D geometry format.
• Robust parsing avoids undefined behavior.
• The parser has no hard-coded limits.
• Article includes full source code.
• Supports vertices, normals, and faces.
