    Looking for Rotating Cube 3D

    I know I have seen a GSP file of a rotating cube, hoping someone can help. I have subscription to LessonLink, but couldn't find it there when I searched.

    I have a coworker that is looking for a rotating cube that also contains a diagonal. But even if it is just a rotating cube without the diagonal, I would appreciate it! Thanks!

    Thank you Vicki. It would be nice if it had complete rotation in all directions, but I will see if this does what she wants.

    Hi Amber,

    There is an activity in SLL called Cube Nets in which students color the faces of a cube to match a net for the cube. The sketch allows students to adjust the spin, pitch and roll to view the cube from all angles. It doesn't have a diagonal, though.
    You'll find it if you search for "cube" in SLL ––*it's a 4–8 activity. If you have trouble finding it, I'll create a student page for it.

    Hi Amber

    My Dynamic Geometry "Student Explorations" site at http://math.kennesaw.edu/~mdevilli/studentexplore.html has JavaSketchpad applets for rotating and viewing all the Platonic solids (but no diagonals) - go to http://math.kennesaw.edu/~mdevilli/platonic.html

    Regards

    And Paul Kunkel's website has a very nice set of 3D tools that allow rotation around all three axes and that show the 3D objects in perspective, giving a nice sense of depth. You can create a cube just by plotting eight points (all eight 3D combinations of -1 and 1, to center it on the origin), and then connecting the vertices. Paul has tools you can use to create the six faces, in such a way that the back faces are hidden, and he even has ways for shading the faces depending on whether they are facing toward or away from the direction of the "light." Here's the URL for the starter tools:

    One more 3D observation: I've just posted a sketch that shows 3D wireframe images of two solids of revolution. One of them shows a disk that you can move or animate through the solid, and the other shows a shell. These sketches can help calculus students visualize these two techniques of integration. The sketch is here: http://sketchexchange.keypress.com/s...sks-and-shells. Another source of Sketchpad images and animations of disks and shells is Audrey Weeks' Calculus in Motion at http://www.calculusinmotion.com/.
