This is not a bug: the OpenGL 4.x Reference documents the OpenGL 4 core context, which does not include the deprecated functions such as glBegin.
These functions are still available in OpenGL 4 compatibility contexts and are documented at https://www.opengl.org/sdk/docs/man2/ , but be aware that they are generally less efficient. ** Changed in: khronos-opengl-man4 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1239792 Title: missing page for glBegin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/khronos-opengl-man4/+bug/1239792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
