Name

lightSpecular()

Description

Sets the specular color for lights. Like fill(), it affects only the elements which are created after it in the code. Specular refers to light which bounces off a surface in a preferred direction (rather than bouncing in all directions like a diffuse light) and is used for creating highlights. The specular quality of a light interacts with the specular material qualities set through the specular() and shininess() functions.

Examples

  • size(400, 400, P3D);
background(0);
noStroke();
directionalLight(102, 102, 102, 0, 0, -1);
lightSpecular(204, 204, 204);
directionalLight(102, 102, 102, 0, 1, -1);
lightSpecular(102, 102, 102);
translate(80, 200, 0);
specular(51, 51, 51);
sphere(120);
translate(240, 0, 0);
specular(102, 102, 102);
sphere(120);
