Description

Sets the specular color of a Py5Shape object’s material, which sets the color of highlight. Specular refers to light which bounces off a surface in a preferred direction (rather than bouncing in all directions like a diffuse light). Use in combination with Py5Shape.emissive(), Py5Shape.ambient(), and Py5Shape.shininess() to set the material properties of a Py5Shape object.

This method can only be used within a Py5Shape.begin_shape() and Py5Shape.end_shape() pair. The specular color setting will be applied to vertices added after the call to this method.

Underlying Processing method: PShape.specular

Syntax

specular(gray: float, /) -> None
specular(rgb: int, /) -> None
specular(x: float, y: float, z: float, /) -> None

Parameters

  • gray: float - value between black and white, by default 0 to 255

  • rgb: int - color to set

  • x: float - red or hue value (depending on current color mode)

  • y: float - green or saturation value (depending on current color mode)

  • z: float - blue or brightness value (depending on current color mode)
