Name screenY() Examples void setup() { size(100, 100, P3D); } void draw() { background(204); float x = mouseX; float y = mouseY; float z = -100; // Draw "X" at z = -100 stroke(255); line(x-10, y-10, z, x+10, y+10, z); line(x+10, y-10, z, x-10, y+10, z); // Draw line in 2D at same y value // Notice the parallax stroke(102); line(0, y, 0, width, y, 0); // Draw 2D line to match the y value // element drawn at z = -100 stroke(0); float theY = screenY(x, y, z); line(0, theY, 0, width, theY, 0); } Description Takes a three-dimensional X, Y, Z position and returns the Y value for where it will appear on a (two-dimensional) screen. Syntax screenY(x, y, z) Parameters x int or float: 3D x coordinate to be mapped y int or float: 3D y coordinate to be mapped z int or float: 3D z coordinate to be mapped Returns float Usage Web & Application Related screenX()screenZ()
