/* GLView: A basic OpenGL rectangle for rendering images.
|
|
|
|
This class is inherited by:
|
|
|
|
*QGLview - for Qt GUI
|
|
*OffscreenView - for offscreen rendering, in tests and from command-line
|
|
(This class is also overridden by NULLGL.cc for special experiments)
|
|
|
|
The view assumes either a Gimbal Camera (rotation,translation,distance)
|
|
or Vector Camera (eye,center/target) is being used. See Camera.h. The
|
|
cameras are not kept in sync.
|
|
|
|
QGLView only uses GimbalCamera while OffscreenView can use either one.
|
|
Some actions (showCrossHairs) only work properly on Gimbal Camera.
