3D Objects, Arrays, and and rotation (Read 1903 times)

wheaties YaBB Newbies Offline Posts: 2	3D Objects, Arrays, and and rotation Apr 28^th, 2010, 10:14pm I would like to know if it is possible to have a grid of 3D objects displayed and change the rotation of one of the objects at a time. I am able to get them to all rotate together but I want to be able to click on one and have it rotate without moving the others. Thanks!!

To pick one you should use the picking library from antiplastik (see this skecth http://www.openprocessing.org/visuals/?visualID=7953).
Apart from that, to do something to one object at time, you must create a Class Cube wich renders a Cube. Then, knowing for example its ID wich could be a property of it, you can call the cube via its ID or some other property wich you may have attached to it, and say: rotateY(some degrees). It should work.

You might like to try the Shapes3D library, not only will it simplify the creation of a range of shapes but has an easy to use 3D picking routine plus a range of rotate methods that can be used on the selected shape.

You can see a demo of shape picking here http://www.lagers.org.uk/s3d4p/applets/s3d4p_shapepicker/index.html
