| typedef View::ViewAngle Viewport::ViewAngle |
Definition at line 42 of file Viewport.h.
| Viewport::Viewport | ( | ) |
Create without sharing OpenGL contexts.
Meshes and textures previously loaded into an exisiting Viewport will not be avaliable in the new one.
Definition at line 15 of file Viewport.cpp.
| Viewport::Viewport | ( | Viewport & | viewport | ) |
Create sharing OpenGL contexts with an exisitng Viewport.
Meshes and textures already loaded will be usable, and any textures or meshes loaded into either the exisiting Viewport or this new one will be avaliable in both.
Definition at line 26 of file Viewport.cpp.
