collada.camera.PerspectiveCamera

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

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.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(collada, localscope, node)	Load and return a class instance from an XML node.
save()	Saves the perspective camera's properties back to xmlnode

xfov	Horizontal field of view, in degrees
yfov	Vertical field of view, in degrees
aspect_ratio	Aspect ratio of the field of view
znear	Distance to the near clipping plane
