#include <s3d.h>

int s3d_push_polygons(int object, const uint32_t *pbuf, uint16_t n);

As for vertices, you can push arrays of polygons to have greater performance. The pbuf should contain n polygons which consist of 4 uint32_t values of 3 vertices indices and 1 material index.

 uint32_t pbuf[] = { 0, 1, 2, 0};
 int oid = s3d_new_object();   // create a new object
 s3d_push_vertex(oid, 0.0, 0.0, 0.0);
 s3d_push_vertex(oid, 0.0, 1.0, 0.0);
 s3d_push_vertex(oid, 1.0, 0.0, 0.0);
 s3d_push_material(oid, 0.3, 0.0, 0.0, 1.0, 1.0, 1.0, 1.0, 0.0, 0.0);
 s3d_push_polygons(oid, pbuf, 1);
 // push one polygon with the pbuf data
