Package eu.svjatoslav.sixth.e3d.renderer.raster.lighting

Class LightSource

java.lang.Object
eu.svjatoslav.sixth.e3d.renderer.raster.lighting.LightSource
public class LightSource extends Object
Represents a light source in the 3D scene with position, color, and intensity.

Light sources emit colored light that illuminates polygons based on their orientation relative to the light. The intensity of illumination follows the Lambert cosine law - surfaces facing the light receive full intensity, while surfaces at an angle receive proportionally less light.

Usage example:


 // Create a yellow light source at position (100, -50, 200)
 LightSource light = new LightSource(
     new Point3D(100, -50, 200),
     Color.YELLOW,
     1.5
 );

 // Move the light source
 light.setPosition(new Point3D(0, 0, 300));

 // Change the light color
 light.setColor(new Color(255, 100, 50));

 // Adjust intensity
 light.setIntensity(2.0);
