Format Object 3 D Rotation Pane. Move the object horizontally. I created a rounded rectangle with a depth of 72 points or 1 inch.
Decrease 3D body standoff height Z-axis by one Snap Grid increment. And if you combine them you have one single matrix. PowerPoint adds the depth to the back of the object.
MODEL WORLD_ROTATION OLD_MODEL OBJECT_ROTATION In this case WORLD_ROTATION rotates about the center of world-space while OBJECT_ROTATION rotates about the center of object-space.
A while ago I went to all the math behind these operations in my blog post about using Leap Motion to get the three rotations of your hand pitch yaw roll to rotate a 3D model. Note that PowerPoint measures depth in points. Rotate 3D body clockwise around its Y-axis. Do any of the following.
