quadratic_vertices()

Create a collection of quadratic vertices.

Examples

import numpy as np

def setup():
    random_quadratic_vertices = 100 * np.random.rand(25, 4)
    with py5.begin_shape():
        py5.vertex(py5.width / 2, py5.height / 2)
        py5.quadratic_vertices(random_quadratic_vertices)

Description

Create a collection of quadratic vertices. The purpose of this method is to provide an alternative to repeatedly calling quadratic_vertex() in a loop. For a large number of quadratic vertices, the performance of quadratic_vertices() will be much faster.

The coordinates parameter should be a numpy array with one row for each quadratic vertex. The first few columns are for the control point and the next few columns are for the anchor point. There should be four or six columns for 2D or 3D points, respectively.

Signatures

quadratic_vertices(
    coordinates: npt.NDArray[np.floating],  # 2D array of quadratic vertex coordinates with 4 or 6 columns for 2D or 3D points, respectively
    /,
) -> None
