Static p5_sys::global::arc

pub static arc: ArcInternalType

Draw an arc to the screen. If called with only x, y, w, h, start and stop, the arc will be drawn and filled as an open pie segment. If a mode parameter is provided, the arc will be filled like an open semi-circle (OPEN), a closed semi-circle (CHORD), or as a closed pie segment (PIE). The origin may be changed with the ellipseMode() function.

The arc is always drawn clockwise from wherever start falls to wherever stop falls on the ellipse.Adding or subtracting TWO_PI to either angle does not change where they fall. If both start and stop fall at the same place, a full ellipse will be drawn. Be aware that the y-axis increases in the downward direction, therefore angles are measured clockwise from the positive x-direction ("3 o'clock").

Examples

arc(50, 55, 50, 50, 0, HALF_PI);
noFill();
arc(50, 55, 60, 60, HALF_PI, PI);
arc(50, 55, 70, 70, PI, PI + QUARTER_PI);
arc(50, 55, 80, 80, PI + QUARTER_PI, TWO_PI);

arc(50, 50, 80, 80, 0, PI + QUARTER_PI);

arc(50, 50, 80, 80, 0, PI + QUARTER_PI, OPEN);

arc(50, 50, 80, 80, 0, PI + QUARTER_PI, CHORD);

arc(50, 50, 80, 80, 0, PI + QUARTER_PI, PIE);

Parameters

x x-coordinate of the arc’s ellipse

y y-coordinate of the arc’s ellipse

w width of the arc’s ellipse by default

h height of the arc’s ellipse by default

start angle to start the arc, specified in radians

stop angle to stop the arc, specified in radians

mode? optional parameter to determine the way of drawing the arc. either CHORD, PIE or OPEN

detail? optional parameter for WebGL mode only. This is to specify the number of vertices that makes up the perimeter of the arc. Default value is 25.
