Py5Shape.ambient()

Sets a Py5Shape object’s ambient reflectance.

Examples

def create_strip(use_ambient):
    s = py5.create_shape()
    s.begin_shape(py5.TRIANGLE_STRIP)
    if use_ambient:
        s.ambient(255, 0, 0)
    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(153, 153, 153, .5, 0, -1)
    py5.ambient_light(50, 50, 50)
    py5.shape(create_strip(False), 0, 5)
    py5.shape(create_strip(True), 0, 50)

Description

Sets a Py5Shape object’s ambient reflectance. This is combined with the ambient light component of the environment. The color components set through the parameters define the reflectance. For example in the default color mode, setting ambient(255, 127, 0), would cause all the red light to reflect and half of the green light to reflect. Use in combination with Py5Shape.emissive(), 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 ambient color setting will be applied to vertices added after the call to this method.

Underlying Processing method: PShape.ambient
