.SH "DESCRIPTION"
.PP
Adds normal information to lines, giving each vertex of a line a normal information\&. This makes lines somewhat nicer, you\*(Aqll need that especially when you\*(Aqre going to build wireframe models\&.
.PP
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\&.
