collada.light.SpotLight

class collada.light.SpotLight(id, color, constant_att=None, linear_att=None, quad_att=None, falloff_ang=None, falloff_exp=None, xmlnode=None)

Spot light as defined in COLLADA tag <spot>.

__init__(id, color, constant_att=None, linear_att=None, quad_att=None, falloff_ang=None, falloff_exp=None, xmlnode=None)

Create a new spot 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

  • constant_att (float) – Constant attenuation factor

  • linear_att (float) – Linear attenuation factor

  • quad_att (float) – Quadratic attenuation factor

  • falloff_ang (float) – Falloff angle

  • falloff_exp (float) – Falloff exponent

  • xmlnode – If loaded from xml, the xml node
