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.
