An option to create a rotation animation for the VectorGraphics 3d object. 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),(0,0,0)); anim2=rotation(-0.1,(0,0,1),(0,0,0)); anim3 = { 5 => {5 => anim1, 5 => anim2}, 10 => anim1 }); |
i2 : gList(Polygon{{(-1,0),(1,0.1),(1,-0.1)},"fill"=>"red",AnimMatrix=>anim1},Circle{(1,0),0.1},Circle{(0,0),1}) o2 = GraphicsList{cache => CacheTable{} } Contents => {Polygon{AnimMatrix => | .995004 -.0998334 0 0 |}, Circle{cache => CacheTable{}}, Circle{cache => CacheTable{}}} | .0998334 .995004 0 0 | Center => | 1 | Center => | 0 | | 0 0 1 0 | | 0 | | 0 | | 0 0 0 1 | | 0 | | 0 | cache => CacheTable{} | 1 | | 1 | fill => red Radius => .1 Radius => 1 Points => {| -1 |, | 1 |, | 1 |} | 0 | | .1 | | -.1 | | 0 | | 0 | | 0 | | 1 | | 1 | | 1 | o2 : GraphicsList |
