NAME
s3d_pep_line_normals - add normals to lines
SYNOPSIS
#include <s3d.h>
int s3d_pep_line_normals(int object, const float *nbuf, uint16_t n);
DESCRIPTION
Adds normal information to lines, giving each vertex of a line a normal
information. This makes lines somewhat nicer, you´ll need that
especially when you´re going to build wireframe models.
nbuf should contain n * 6 float values, for each vertex a normal vector
(x,y,z), and you have 2 vertices for each line so that makes 6 float
values per line in total.
