Reading .obj without triangulation. Use `num_vertices[i]` to iterate over faces(indices). `num_vertices[i]` stores the number of vertices for ith face.
```c++
#define TINYOBJLOADER_IMPLEMENTATION // define this in only *one* .cc
#include "tiny_obj_loader.h"
std::string inputfile = "cornell_box.obj";
std::vector<tinyobj::shape_t> shapes;
std::vector<tinyobj::material_t> materials;
std::string err;
bool triangulate = false;
bool ret = tinyobj::LoadObj(shapes, materials, err, inputfile.c_str(), triangulate);
if (!err.empty()) { // `err` may contain warning message.
std::cerr << err << std::endl;
}
if (!ret) {
exit(1);
}
for (size_t i = 0; i < shapes.size(); i++) {
size_t indexOffset = 0;
for (size_t n = 0; n < shapes[i].mesh.num_vertices.size(); n++) {
int ngon = shapes[i].mesh.num_vertices[n];
for (size_t f = 0; f < ngon; f++) {
unsigned int v = shapes[i].mesh.indices[indexOffset + f];
printf(" face[%ld] v[%ld] = (%f, %f, %f)\n", n,
shapes[i].mesh.positions[3*v+0],
shapes[i].mesh.positions[3*v+1],
shapes[i].mesh.positions[3*v+2]);
}
indexOffset += ngon;
