An option to create a rotation animation for the GraphicsObject. The value can be a single 4x4 matrix, or a list which is cycled. The syntax n => ... can be used to repeat a sequence n times (where 0} means infinity). The animation automatically loops (use 0 => { } to stop!) In order for the animation to work, VectorGraphics.css and VectorGraphics.js must be included in the web page.
i1 : (anim1=rotation(0.1,[0,0,1],[0,0]); anim2=rotation(-0.1,[0,0,1],[0,0]);); anim3 = { 5 => {5 => anim1, 5 => anim2}, 10 => anim1 };
