democratizing Digital Twins with Progressive 3D Reconstruction
Brief
demoConstruct is an open-source platform that enables accessible and collaborative scene authoring, powered by progressive 3D reconstruction.
Designed to accommodate both professionals and untrained users, the experience is delivered through interfaces that run on common consumer devices.
demoConstruct’s progressive 3D reconstruction approach enables near real-time 3D reconstruction which supports simultaneous parallel operations across diverse user roles:
- scene capturing and digitization using a mobile camera,
- scene editing on a desktop PC, and
- scene exploration and inspection on a VR headset.
This platform powers many different use cases of digital twins and one of our current focus is in the healthcare sector, where we are working with Tan Tock Seng Hospital (TTSH) in Singapore.
