Draws a point, a coordinate in space at the dimension of one pixel. The first
parameter is the horizontal value for the point, the second value is the
vertical value for the point, and the optional third value is the depth
value. Drawing this shape in 3D with the z parameter requires the P3D
parameter in combination with size() as shown in the above example.
Use stroke() to set the color of a point().
Point appears round with the default strokeCap(ROUND) and square with strokeCap(PROJECT). Points are invisible with strokeCap(SQUARE) (no cap).
Using point() with strokeWeight(1) or smaller may draw nothing to the screen, depending on the graphics settings of the computer. Workarounds include setting the pixel using set() or drawing the point using either circle() or square().
size(400, 400); noSmooth(); point(120, 80); point(340, 80); point(340, 300); point(120, 300);
size(400, 400, P3D); noSmooth(); point(120, 80, -200); point(340, 80, -200); point(340, 300, -200); point(120, 300, -200);
point(x, y, z)
(float)x-coordinate of the point
(float)y-coordinate of the point
(float)z-coordinate of the point
