      • GlobalLightSource

        public GlobalLightSource​(float azimuth,
                         float height,
                         com.badlogic.gdx.graphics.Color tone,
                         com.badlogic.gdx.graphics.Color ambient,
                         float brghtFac,
                         int amplitudeHeight)
        A GlobalLightSource can be the moon, the sun or even something new.
        Parameters:
        azimuth - The starting position in degrees from left. CCW
        height - The starting position in degrees above the horizon.
        tone - the starting color of the light. With this parameter you do not controll its brightness.
        ambient - color vector
        brghtFac - brightness factor 0.5f is default. the higher the brighter
        amplitudeHeight - the maximum degree during a day the LightSource rises

    • Method Detail

      • getPower

        public float getPower​()
        A light source shines can shine brighter and darker. This amplitude is called power. What it real emits says the resulting light.
        Returns:
        a value between 0 and 1

      • getTone

        public com.badlogic.gdx.graphics.Color getTone​()
        Returns:

      • getHeight

        public float getHeight​()
        current height above horizon
        Returns:
        in degrees 0-360°

      • getAzimuth

        public float getAzimuth​()
        origin is left side
