Name

specular()

Description

Sets the specular color of the materials used for shapes drawn to the screen, which sets the color of highlights. Specular refers to light which bounces off a surface in a preferred direction (rather than bouncing in all directions like a diffuse light). Used in combination with emissive(), ambient(), and shininess() in setting the material properties of shapes.

Examples

  • size(400, 400, P3D);
background(0);
noStroke();
background(0);
fill(0, 51, 102);
lightSpecular(255, 255, 255);
directionalLight(204, 204, 204, 0, 0, -1);
translate(80, 200, 0);
specular(255, 255, 255);
sphere(120);
translate(240, 0, 0);
specular(204, 102, 0);
sphere(120);
