util3d is a collection of C modules and headers implementing useful functions for programmers working with 3D graphics in OpenGL. This code is made available under the terms of the MIT/X11 License and is free for any and all uses.
math3d — Implements a right-handed 3D mathematics library supporting three-component vectors, four-by-four matrices, quaternions, and Euler angles.
demo — Implements a very simple framework for OpenGL demonstration applications.
image — Provides a basic image I/O library supporting the reading and writing of PNG, TIFF, JPEG, and OpenEXR images.
cube — Renders the 3D reference cube using OpenGL. Useful for testing 3D transformations and debugging OpenGL applictions.
obj — Loads, manipulates, optimizes, renders, and stores 3D geometry using the Wavefront OBJ file format.
glsl — Manages GLSL shader source and program objects.
type — Renders text using OpenGL. Useful for adding GUI elements and labels to 3D graphics applications.
noise — Implements a 3D coherent noise generator using the Simplex method of Ken Perlin.
plane — Renders a simple 3D plane using OpenGL. Useful as a basic scene backdrop.
