# glu

### MODULE

glu

### MODULE SUMMARY

A part of the standard OpenGL Utility api.

### DESCRIPTION

A part of the standard OpenGL Utility api. See www.opengl.org

Booleans are represented by integers 0 and 1.

### DATA TYPES

clamp()

  A float clamped between 0.0 - 1.0

enum()

  An integer defined in gl.hrl

mem()

  memory block

offset()

  An integer which is an offset in an array

### EXPORTS

tesselate(X1::Vec3, Vs::[Vec3]) -> {Triangles, VertexPos}

Types:

Vec3 = {float(), float(), float()}
Triangles = [VertexIndex::integer()]
VertexPos = binary()

General purpose polygon triangulation. The first argument is the normal and the second a list of vertex positions. Returned is a list of indecies of the vertices and a binary (64bit native float) containing an array of vertex positions, it starts with the vertices in Vs and may contain newly created vertices in the end.
