__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:

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

Methods

__init__(id, znear, zfar[, xfov, yfov, …]) Create a new perspective camera.
bind(matrix) Create a bound camera of itself based on a transform matrix.
load(localscope, node)
save() Saves the perspective camera’s properties back to xmlnode
id = None

Identifier for the camera

xfov = None

Horizontal field of view, in degrees

yfov = None
