Description

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.

Syntax

quad(x1, y1, x2, y2, x3, y3, x4, y4)

Parameters

x1 – x-coordinate of the first point

y1 – y-coordinate of the first point

x2 – x-coordinate of the second point

y2 – y-coordinate of the second point

x3 – x-coordinate of the third point

y3 – y-coordinate of the third point

x4 – x-coordinate of the fourth point

y4 – y-coordinate of the fourth point

Returns

none

Bugs
The following code test keeps erasing when I try to draw a polygon:

void setup()
{
background(0,0,0);// set the screen black
stroke(255,0,0); //set color to red
}

void loop()
{
quad(10, 10, 4, 97, 112, 78, 103, 18);
}
