Camera
|
|
|
|
For usage, see QGLView.cc, GLView.cc, export_png.cc, openscad.cc
|
|
|
|
There are two different types of cameras represented in this class:
|
|
|
|
*Gimbal camera - uses Euler Angles, object translation, and viewer distance
|
|
*Vector camera - uses 'eye', 'center', and 'up' vectors ('lookat' style)
|
|
|
|
They are not necessarily kept in sync. There are two modes of
|
|
projection, Perspective and Orthogonal.
