lights() / Reference / Processing.org

Name

lights()

Description

Sets the default ambient light, directional light, falloff, and specular values. The defaults are ambientLight(128, 128, 128) and directionalLight(128, 128, 128, 0, 0, -1), lightFalloff(1, 0, 0), and lightSpecular(0, 0, 0). Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop.

Examples

```
size(400, 400, P3D);
background(0);
noStroke();
// Sets the default ambient 
// and directional light
lights();
translate(80, 200, 0);
sphere(120);
translate(240, 0, 0);
sphere(120);
```
```
void setup() {
  size(400, 400, P3D);
  background(0);
  noStroke();
}

void draw() {
  // Include lights() at the beginning
  // of draw() to keep them persistent 
  lights();
  translate(80, 200, 0);
  sphere(120);
  translate(240, 0, 0);
  sphere(120);
}
```
