Graham Street | Hong Kong (Workshop Space 01)

This Opus Lab Workshop Space "Graham Street" illustrates several approaches to 3DGS reconstruction of Graham Street, Central, Hong Kong Island, Hong Kong. We used the XGRIDS PortalCam to make a SLAM-based reconstruction, which proved particularly challenging as it was performed at nighttime. We also used Marble Mini and Plus (0.1) by World Labs, SHARP by Apple and Hunyuan World-Mirror by Tencent to reconstruct part of the street based on a single photo uploaded as a prompt. These three methods demonstrate different approaches to generating 3D reconstructions, ranging from real-world multi-frame and multi-spectral capture, through text and image prompting (cloud-processed), to local 3DGS generation based on a single photo.
