NAME

       s3d_pep_polygon_normals - add normals to polygon

SYNOPSIS

       #include <s3d.h>

       int s3d_pep_polygon_normals(int object, const float *nbuf, uint16_t n);

DESCRIPTION

       Adds normal information to polygons, giving each vertex of a polygon a normal information.
       With this, you can achieve smoothed edge effects.

       nbuf should contain n * 9 float values, for each vertex a normal vector (x,y,z), and you
       have 3 vertices for each Polygon so that makes 9 float values per Polygon in total. Don't
       worry if you don't use this, it's kind of hard to calculate and the server will always use
       some proper normal values (same for every vertex, calculated by the plane which is defined
       by the 3 points of the polygon.
