Py5Shape.emissive()

Py5Shape.emissive()#

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

Examples#

example picture for emissive()

def create_strip(use_emissive):
    s = py5.create_shape()
    s.begin_shape(py5.TRIANGLE_STRIP)
    if use_emissive:
        s.emissive(0, 50, 100)
    s.vertex(10, 40, -25)
    s.vertex(20, 0, -10)
    s.vertex(30, 40, 0)
    s.vertex(40, 0, 5)
    s.vertex(50, 40, 0)
    s.vertex(60, 0, -10)
    s.vertex(70, 40, -25)
    s.end_shape()
    return s


def setup():
    py5.size(100, 100, py5.P3D)
    py5.background(0)
    py5.directional_light(200, 200, 200, .5, 0, -1)
    py5.shape(create_strip(False), 0, 5)
    py5.shape(create_strip(True), 0, 50)

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.

This method has additional color functionality that is not reflected in the method’s signatures. For example, you can pass the name of a color (e.g. “green”, “mediumpurple”, etc). Look at the online “All About Colors” Python Ecosystem Integration tutorial for more information.

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
