line()

Name

Examples

line(30, 20, 85, 75);

line(30, 20, 85, 20);

stroke(126);

line(85, 20, 85, 75);

stroke(255);

line(85, 75, 30, 75);

// Drawing lines in 3D requires P3D

// or OPENGL as a parameter to size()

size(100, 100, P3D);

line(30, 20, 0, 85, 20, 15);

stroke(126);

line(85, 20, 15, 85, 75, 0);

stroke(255);

line(85, 75, 0, 30, 75, -50);

Description

Draws a line (a direct path between two points) to the screen. The version of line() with four parameters draws the line in 2D. To color a line, use the stroke() function. A line cannot be filled, therefore the fill() method will not affect the color of a line. 2D lines are drawn with a width of one pixel by default, but this can be changed with the strokeWeight() function. The version with six parameters allows the line to be placed anywhere within XYZ space. Drawing this shape in 3D using the z parameter requires the P3D or OPENGL parameter in combination with size as shown in the above example.

Syntax

line(x1, y1, x2, y2)

line(x1, y1, z1, x2, y2, z2)

Parameters

x1	int or float: x-coordinate of the first point
y1	int or float: y-coordinate of the first point
z1	int or float: z-coordinate of the first point
x2	int or float: x-coordinate of the second point
y2	int or float: y-coordinate of the second point
z2	int or float: z-coordinate of the second point

Usage

Web & Application
