Name | ### ellipseMode()
Examples |
    ellipseMode(RADIUS);  // Set ellipseMode to RADIUS
    fill(255);  // Set fill to white
    ellipse(50, 50, 30, 30);  // Draw white ellipse using RADIUS mode

    ellipseMode(CENTER);  // Set ellipseMode to CENTER
    fill(100);  // Set fill to gray
    ellipse(50, 50, 30, 30);  // Draw gray ellipse using CENTER mode
    ellipseMode(CORNER);  // Set ellipseMode is CORNER
    fill(255);  // Set fill to white
    ellipse(25, 25, 50, 50);  // Draw white ellipse using CORNER mode

    ellipseMode(CORNERS);  // Set ellipseMode to CORNERS
    fill(100);  // Set fill to gray
    ellipse(25, 25, 50, 50);  // Draw gray ellipse using CORNERS mode
Description | Modifies the location from which ellipses are drawn by changing the way in which parameters given to ellipse() are intepreted. The default mode is ellipseMode(CENTER), which interprets the first two parameters of ellipse() as the shape's center point, while the third and fourth parameters are its width and height. ellipseMode(RADIUS) also uses the first two parameters of ellipse() as the shape's center point, but uses the third and fourth parameters to specify half of the shapes's width and height. ellipseMode(CORNER) interprets the first two parameters of ellipse() as the upper-left corner of the shape, while the third and fourth parameters are its width and height. ellipseMode(CORNERS) interprets the first two parameters of ellipse() as the location of one corner of the ellipse's bounding box, and the third and fourth parameters as the location of the opposite corner. The parameter must be written in ALL CAPS because Processing is a case-sensitive language.
