An OpenGL wrapper for Ruby. opengl contains bindings for OpenGL.
Features and Problems
available for Windows, Linux and OS X
require 'opengl' FIX (code sample of usage)
see 0.7 for Ruby 1.8.x compatible branch
OpenGL development files installed
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.
gem install opengl
After checking out the source, run:
$ rake newb
This task will install any missing dependencies, run the tests/specs, and generate the RDoc.
Cross compiling for Windows
Using rake-compiler a cross compiled opengl gem can be build in a rake-compiler-dev-box the win32 platform. There are no runtime dependencies to any but the standard Windows DLLs. Use the standard package_win32_fat_binary script.
