s3d_pep_polygon_norm(3)
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.
