What is this?

It is a tool who convert [3D OBJ model] OBJ SPEC files into C arrays. I wrote this tool for a small university project in which I could not use an OBJ loader. This is really quick & dirty work and should be use with caution in real project.

Usage

./ConvertObj -in model.obj -out model_array.h

The header result file could be use this way:

#include "model_array.h"

void createStructure(const float* points, int size) const {
	glVertexPointer(3, GL_FLOAT, 0, points);
	glDrawArrays(GL_TRIANGLES, 0, size/3);
}

createStructure(array_name, sizeof(array_name)/sizeof(float));

Known Limitations

• Process only geometric vertices, objects and faces
• Only faces with 3 or 4 vertices are managed
• Probably more…
