Class LightGlow

java.lang.Object

gaiasky.render.postprocess.PostProcessorEffect

gaiasky.render.postprocess.effects.LightGlow

All Implemented Interfaces:

com.badlogic.gdx.utils.Disposable

public final class LightGlow
extends PostProcessorEffect

A post-processor effect that renders a glow around light sources like stars and planets.

It uses a GlowFilter to compute the glow texture based on the light positions, sizes, and colors. This effect can be configured with various parameters like blending mode, texture scale, and the number of samples for the glow calculation.
