collada.scene.LookAtTransform

class collada.scene.LookAtTransform(eye, interest, upvector, xmlnode=None)

Contains a transformation for aiming a camera as defined in the collada <lookat> tag.

__init__(eye, interest, upvector, xmlnode=None)

Creates a lookat transformation

Parameters:

• eye (numpy.array) – An unshaped numpy array of floats of length 3 containing the position of the eye

• interest (numpy.array) – An unshaped numpy array of floats of length 3 containing the point of interest

• upvector (numpy.array) – An unshaped numpy array of floats of length 3 containing the up-axis direction

• xmlnode – When loaded, the xmlnode it comes from

Methods

__init__(eye, interest, upvector[, xmlnode])	Creates a lookat transformation
load(collada, node)	Load and return a class instance from an XML node.
save()	Put all the data to the internal xml node (xmlnode) so it can be serialized.

Attributes

xmlnode	ElementTree representation of the transform.
eye	A numpy array of length 3 containing the position of the eye
interest	A numpy array of length 3 containing the point of interest
upvector	A numpy array of length 3 containing the up-axis direction
matrix	The resulting transformation matrix.
