LibGLUT

LibGLUT offers Crystal bindings for Freeglut.

A few adjustments have been made to nomenclature to follow the Crystal style guide and improve readability:

• the glut prefix has been removed from all functions and constants.
• method names are snake_case rather than camelCase.

Installation

Add this to your application's shard.yml:

dependencies:
  lib_glut:
    github: neutrinog/lib_glut

You must also install cmake, freeglut, and opengl.

Usage

require "lib_glut"

Extensions

Since freeglut does not currently support passing context to callback functions I've included some additional methods that add this feature. All extensions are named after their corresponding function with an _x appended.

For example:

LibGLUT.display_func # standard freeglut method
LibGLUT.display_func_x # extended function with support for passing in a context.

The ability to pass context to a c function means we can preserve closure while calling these methods.
