Description
An OpenGL wrapper for Ruby. opengl contains bindings for OpenGL.
Be sure to check out GLU and GLUT gems.
Features and Problems
-
available for Windows, Linux and OS X
Synopsis
require 'opengl'
FIX (code sample of usage)
Requirements
-
Ruby 1.9.2+
-
OpenGL runtime libraries installed
Install
gem install opengl
Developers
After checking out the source, run:
bundle install
This will install missing dependencies.
Tests
Run the tests with:
rake test
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.
