• An extension library for MRI
  • More faster and memory efficient
• Provides same interface
  • (In theory) You don't have to rewrite your code.

1. $ gem install opengl-bindings_c
2. require 'opengl'
   • opengl-bindings (v1.5.1 and later) tries to load opengl_c first.

• There's no need to use this gem if you don't suffer performance/memory matter.

• glGetString and glGetStringi return String instance.

• APIs listed below return Fiddle::Pointer instance.

  • glMapBuffer
  • glMapBufferRange
  • glFenceSync
  • glMapNamedBuffer
  • glMapNamedBufferRange
  • glCreateSyncFromCLeventARB
  • glGetHandleARB
  • glCreateShaderObjectARB
  • glCreateProgramObjectARB
  • glMapBufferARB
  • glMapObjectBufferATI
  • glMapNamedBufferEXT
  • glMapNamedBufferRangeEXT
  • glImportSyncEXT
  • glMapTexture2DINTEL
