__init__
(id, znear, zfar, xfov=None, yfov=None, aspect_ratio=None, xmlnode=None)¶ Create a new perspective camera.
Note:
aspect_ratio = tan(0.5*xfov) / tan(0.5*yfov)
- You can specify one of:
xfov
aloneyfov
alonexfov
andyfov
xfov
andaspect_ratio
yfov
andaspect_ratio
Any other combination will raise
collada.common.DaeMalformedError
Parameters: - id (str) – Identifier for the camera
- znear (float) – Distance to the near clipping plane
- zfar (float) – Distance to the far clipping plane
- xfov (float) – Horizontal field of view, in degrees
- yfov (float) – Vertical field of view, in degrees
- aspect_ratio (float) – Aspect ratio of the field of view
- xmlnode – If loaded from xml, the xml node
