Name	curve()
Examples	noFill(); stroke(255, 102, 0); curve(5, 26, 5, 26, 73, 24, 73, 61); stroke(0); curve(5, 26, 73, 24, 73, 61, 15, 65); stroke(255, 102, 0); curve(73, 24, 73, 61, 15, 65, 15, 65);
Description	Draws a curved line on the screen. The first and second parameters specify the beginning control point and the last two parameters specify the ending control point. The middle parameters specify the start and stop of the curve. Longer curves can be created by putting a series of curve() functions together or using curveVertex(). An additional function called curveTightness() provides control for the visual quality of the curve. The curve() function is an implementation of Catmull-Rom splines. Using the 3D version requires rendering with P3D (see the Environment reference for more information).
Syntax	curve(x1, y1, x2, y2, x3, y3, x4, y4) curve(x1, y1, z1, x2, y2, z2, x3, y3, z3, x4, y4, z4)
Parameters	x1 float: coordinates for the beginning control point y1 float: coordinates for the beginning control point x2 float: coordinates for the first point y2 float: coordinates for the first point x3 float: coordinates for the second point y3 float: coordinates for the second point x4 float: coordinates for the ending control point y4 float: coordinates for the ending control point z1 float: coordinates for the beginning control point z2 float: coordinates for the first point z3 float: coordinates for the second point z4 float: coordinates for the ending control point
Returns	void
