collada.light.DirectionalLight

class collada.light.DirectionalLight(id, color, xmlnode=None)

Bases: collada.light.Light

Directional light as defined in COLLADA tag <directional> tag.

__init__(id, color, xmlnode=None)

Create a new directional light.

Parameters:

• id (str) – A unique string identifier for the light
• color (tuple) – Either a tuple of size 3 containing the RGB color value of the light or a tuple of size 4 containing the RGBA color value of the light
• xmlnode – If loaded from xml, the xml node

Methods

__init__(id, color[, xmlnode])	Create a new directional light.
bind(matrix)	Binds this light to a transform matrix.
load(collada, localscope, node)	Load and return a class instance from an XML node.
save()	Saves the light’s properties back to xmlnode

id = None

The unique string identifier for the light

color = None

Either a tuple of size 3 containing the RGB color value of the light or a tuple of size 4 containing the RGBA color value of the light

xmlnode = None

ElementTree representation of the light.

save()

Saves the light’s properties back to xmlnode

static load(collada, localscope, node)

Load and return a class instance from an XML node.

Inspect the data inside node, which must match this class tag and create an instance out of it.

Parameters:

• collada (collada.Collada) – The collada file object where this object lives
• localscope (dict) – If there is a local scope where we should look for local ids (sid) this is the dictionary. Otherwise empty dict ({})
• node – An Element from python’s ElementTree API

bind(matrix)

Binds this light to a transform matrix.

Parameters:matrix (numpy.array) – A 4x4 numpy float matrix Return type:collada.light.BoundDirectionalLight
