panda3d.core.Light¶
from panda3d.core import Light
-
class
Light¶ The abstract interface to all kinds of lights. The actual light objects also inherit from PandaNode, and can therefore be added to the scene graph at some arbitrary point to define the coordinate system of effect.

-
isAmbientLight() → bool¶ Returns true if this is an AmbientLight, false if it is some other kind of light.
-
getColor() → LColor¶ Returns the basic color of the light.
- Return type
LColor
-
setColor(color: LColor) → None¶ Sets the basic color of the light.
-
hasColorTemperature() → bool¶ Returns true if the color was specified as a temperature in kelvins, and get_color_temperature is defined.
New in version 1.10.0.
-
getColorTemperature() → float¶ Returns the basic color temperature of the light, assuming
hasColorTemperature()returns true.New in version 1.10.0.
-
setColorTemperature(temperature: float) → None¶ Sets the color temperature of the light in kelvins. This will recalculate the light’s color.
The default value is 6500 K, corresponding to a perfectly white light assuming a D65 white point.
New in version 1.10.0.
-
getExponent() → float¶ For spotlights, returns the exponent that controls the amount of light falloff from the center of the spotlight. For other kinds of lights, returns 0.
-
getSpecularColor() → LColor¶ Returns the color of specular highlights generated by the light. This value is meaningless for ambient lights.
- Return type
LColor
-
getAttenuation() → LVecBase3¶ Returns the terms of the attenuation equation for the light. These are, in order, the constant, linear, and quadratic terms based on the distance from the point to the vertex.
- Return type
LVecBase3
-
setPriority(priority: int) → None¶ Changes the relative importance of this light relative to the other lights that are applied simultaneously.
The priority number is used to decide which of the requested lights are to be selected for rendering when more lights are requested than the hardware will support. The highest-priority n lights are selected for rendering.
This is similar to
TextureStage.setPriority().
-
getPriority() → int¶ Returns the priority associated with this light. See
setPriority().
-
getClassPriority() → int¶
-
static
getClassType() → TypeHandle¶ - Return type
