Learn how to create a digitized version of a curved surface topology with this easy to use computer vision tool in augmented reality with Fologram. If you’re working with curved physical geometries and want to create live digitized versions, or you’re just interested in learning the basics of computer vision in AR, this is a perfect example to get started with.
Doubly curved surfaces are notoriously difficult to accurately fabricate, and documenting the outcomes often relies on complex setups involving point cloud scans. Fologram’s marker tracking tools can be used to visualize surface curvature in AR, and create an accurate digital copy of your surfaces in grasshopper.
The tool tracks a grid of Aruco marker locations in physical space and updates the surface curvature live in augmented reality, with the digital copy of your surface sent straight back to your grasshopper document, where you can check the accuracy against your digital model. The feedback is live and requires no extra equipment other than a HoloLens or mobile device.
