quad

quad()

Description

Draws a quad on the canvas. A quad is a quadrilateral, a four-sided polygon. It is similar to a rectangle, but the angles between its edges are not constrained to ninety degrees. The first pair of parameters (x1, y1) sets the first vertex and the subsequent pairs should proceed clockwise or counter-clockwise around the defined shape. z-arguments only work when quad() is used in WEBGL mode.

Examples

from proceso import Sketch


p5 = Sketch()
p5.describe("Irregular white quadrilateral with black outline")

p5.quad(38, 31, 86, 20, 69, 63, 30, 76)

Syntax

quad(x1, y1, x2, y2, x3, y3, x4, y4, [detail_x], [detail_y])

quad(x1, y1, z1, x2, y2, z2, x3, y3, z3, x4, y4, z4, [detail_x], [detail_y])

Parameters

x1: float x-coordinate of the first point.

y1: float y-coordinate of the first point.

x2: float x-coordinate of the second point.

y2: float y-coordinate of the second point.

x3: float x-coordinate of the third point.

y3: float y-coordinate of the third point.

x4: float x-coordinate of the fourth point.

y4: float y-coordinate of the fourth point.

[detail_x]: int Number of segments in the x-direction.

[detail_y]: int Number of segments in the y-direction.

z1: float z-coordinate of the first point.

z2: float z-coordinate of the second point.

z3: float z-coordinate of the third point.

z4: float z-coordinate of the fourth point.
