In order to visualize Multi-Variable Calculus 3d shapes in real space as well as other 3D content, I have started developing Augmented Reality apps using the Vuforia SDK. Here are some screenshots from what I have done so far:
The previous 4 images showcase the 3d visualization of a height map. The first one shows the 2d version of the map, and the second one shows what it would look projected upward in 3D. The 3rd one shows how the 3D height map and actual shape line up, and the last image is just the actual shape projected over the height map.
