Class PShape Name rotateZ() Examples PShape s; void setup() { size(100, 100, P3D); s = loadShape("ohio.svg"); } void draw() { background(204); shape(s); } void mousePressed() { // Rotate the shape around the z-axis each time the mouse is pressed s.rotateZ(0.1); } Description Rotates a shape around the z-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method. Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect. For example, calling rotateZ(HALF_PI) and then rotateZ(HALF_PI) is the same as rotateZ(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run. This method requires a 3D renderer. You need to pass P3D or OPENGL as a third parameter into the size() method as shown in the example above. Syntax sh.rotateZ(angle) Parameters sh PShape: any variable of type PShape angle float: angle of rotation specified in radians Returns none Usage Web & Application Updated on June 14, 2010 12:05:29pm EDT Processing was initiated by Ben Fry and Casey Reas. It is developed by a small team of volunteers. © Info \ Site hosted by Media Temple!
