PointLight¶

class pyrender.light.PointLight(color=None, intensity=None, range=None, name=None)[source]¶

Bases: pyrender.light.Light

Point lights emit light in all directions from their position in space; rotation and scale are ignored except for their effect on the inherited node position. The brightness of the light attenuates in a physically correct manner as distance increases from the light’s position (i.e. brightness goes like the inverse square of the distance). Point light intensity is defined in candela, which is lumens per square radian (lm/sr).

Parameters:	color ((3,) float) – RGB value for the light’s color in linear space. intensity (float) – Brightness of light in candela (lm/sr). range (float) – Cutoff distance at which light’s intensity may be considered to have reached zero. If None, the range is assumed to be infinite. name (str, optional) – Name of the light.

Attributes Summary

`color`	The light’s color.
`intensity`	The light’s intensity in candela or lux.
`name`	The user-defined name of this object.
`range`	The cutoff distance for the light.
`shadow_texture`	A texture used to hold shadow maps for this light.
