collada.scene.LookAtTransform

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

Bases: collada.scene.Transform

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)
save()
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. This will be a numpy.array of size 4x4.

xmlnode

ElementTree representation of the transform.
