IR/ToF Depth Sensor
Our AR Sandbox utilizes advanced depth sensors (such as Kinect or RealSense) to scan the sand surface in real-time. An overhead projector instantly applies topographic color maps, contour lines, and dynamic fluid simulations (water/lava) as you mold the terrain with your hands. It is a powerful tool for geospatial data visualization and interactive education.

A front end library is being released every day and it is requested to master these technologies.I also follow the market every day and follow the updates of new frontend frameworks and programming frameworks. It is easier for me to keep up with new technologies in projects
You need four main components: a PC with a dedicated GPU (NVIDIA recommended), a depth sensor (Kinect v2 or Intel RealSense), a digital projector, and a physical box filled with white sand.
We migrated to Unity 3D to leverage advanced fluid physics, better graphical rendering, and easier installation on Windows systems, making the tool more accessible for schools and researchers.
The depth sensor scans the sand surface 30 times per second. Our software translates this height data into a topographic color map, which is then projected back onto the sand in perfect alignment.
It is ideal for Geography (topography, contour lines), Geology (erosion, landforms), and Hydrology (watersheds, dams, and flooding simulations).
Initial calibration aligns the camera and projector. Once set up, the system typically requires little maintenance unless the physical projector is moved. We are currently researching auto-calibration methods.
The project originated from open-source principles. Currently, as part of Master's research, specific modules are under development, but we aim to contribute back to the community with documentation and code.
Download versions v1.0, v1.1, and v1.2. Includes new water physics, waterfalls, and gesture interaction features.
