Py5Shape.emissive()#

Sets the emissive color of a Py5Shape object’s material.

Examples#

Description#

Sets the emissive color of a Py5Shape object’s material. Use in combination with Py5Shape.ambient(), Py5Shape.specular(), 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 emissive color setting will be applied to vertices added after the call to this method.

Underlying Processing method: PShape.emissive

Signatures#

emissive(
    gray: float,  # value between black and white, by default 0 to 255
    /,
) -> None

emissive(
    rgb: int,  # color to set
    /,
) -> None

emissive(
    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)
    /,
) -> None
