Package glitter :: Package contexts :: Module glut

Module glut

GLUT context creation and management.

Bug: Closing a GLUT window via the window system (not the API) causes bogus error messages and even the occasional segfault.

To Do:

Implement subwindows using glutCreateSubWindow and glutGet(GLUT_WINDOW_PARENT).
Implement menus, font rendering, and geometric object rendering,
Fail gracefully (better error message) when context cannot be created, e.g. when opengl 3.2 not available
Key constants like GLUT_KEY_F1 should be available as an enum.
