*Attention*: This project is in maintenance mode. It might receive bug fixes or adjustments for new Ruby versions, but no new features (like support for newer OpenGL versions). The recommended migration path is to use opengl-binding. It makes use of the Khronos XML API registry, so that it's more up-to-date and easier to maintain but it uses a different Ruby-API than this project.
An OpenGL wrapper for Ruby. opengl contains bindings for OpenGL.
Features and Problems
available for Windows, Linux and OS X
supports OpenGL up to 3.0 - please move to opengl-bindings for more recent OpenGL versions
require 'opengl' FIX (code sample of usage)
OpenGL runtime libraries installed
gem install opengl
After checking out the source, run:
This will install missing dependencies.
Run the tests with:
Note that the tests have the adverse effect of testing the underlying OpenGL implementation, so depending on your GL provider, drivers or OS, the tests may fail, crash, or not run at all, without affecting your ability to use the bindings.
Tests require both glut and glu gem.
With our test suite, we were able to uncover and help fix upstream mesa bugs:
#61026 glBitmap segfault
#61003 gluSurface with Nurbs spits out debug code
#61395 glEdgeFlag can't be set to false
Whenever a test or example fails, it should be quickly ported into a simple C test program, so we can determine whether it's a bug in the bindings or the OpenGL implementation.
Cross compiling for Windows
A cross compiled opengl gem can be build per rake-compiler-dock for the Windows platform. There are no runtime dependencies to any but the standard Windows DLLs. Run rake gem:windows and find the gem files in the pkg directory.
