PointLight
A point light which can be located at a specific point in a scene and illuminates in all directions.
Properties:
ambientIntensity
affects the ambient (indirect) lighting for lit objects. The ambient lighting is computed (for each of red, green, and blue) by multiplying the light's intensity by its ambientIntensity, and multiplying the result for that color component.
attenuation
specifies three coefficients to be used in calculating an attenuating factor. The first number is for the constant attenuation, the second for linear attenuation over distance, and the third for quadratic attenuation.
color
specifies the spectral color properties of both the direct and ambient light emission as an RGB value.
intensity
specifies the brightness in the range from 0.0 (no light emission) to 1.0 (full intensity).
on
on indicates whether the light is turned on (True) or off (False).
radius
indicates how far away from the light an object can be still lit.
Events:
Events correspond to the object properties description. All incoming events are repeated as the outgoing ones.
