YORIS (Your Object Rotates In Stereo) renders 3D objects defined in Wavefront .obj format onto the screen of your Psion. The extra width of the Psion screen is used to display a second image.
By focusing your eyes correctly on these two images (or by holding a piece of cardboard between the images), you can see it as one image with full 3D effects. Then with a few strokes of your pen, you can rotate the image to view it from any angle.
This program uses a lot of memory, but it is worth it to see your objects in 3D. |
