Re: Rotation of a cube Reply #1 - Jul 16th, 2006, 3:48am   You may want to take a look at the ArcBall library. http://www.processinghacks.com/hacks/arcball I hacked up the code found at http://processing.org/learning/examples/rotate3d.html a little bit and came up with this... maybe more along what you were thinking of... Quote: float a = 0.0; float b = 0; void setup() {  size(200, 200, P3D);  noStroke();  fill(204, 204);  framerate(30); } void draw() {  background(0);  pointLight(100, 156, 200, 35, 40, 50);  translate(width/2, height/2);  if(mouseX != pmouseX && mousePressed){    b += mouseX-pmouseX;  }  if(mouseY != pmouseY && mousePressed){    a -= mouseY-pmouseY;  }  rotateX(radians(a));  rotateY(radians(b));  box(width/4); }
