collada.camera.PerspectiveCamera

class collada.camera.PerspectiveCamera(id, znear, zfar, xfov=None, yfov=None, aspect_ratio=None, xmlnode=None)

Bases: collada.camera.Camera

Perspective camera as defined in COLLADA tag <perspective>.

__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 alone
• yfov alone
• xfov and yfov
• xfov and aspect_ratio
• yfov and aspect_ratio

Any other combination will raise collada.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(collada, localscope, node)
save()	Saves the perspective camera’s properties back to xmlnode
