CHCNAV CoViewer is a free, lightweight desktop viewer for 3D Gaussian Splatting (3DGS) models. It lets you open, explore and present photorealistic 3D scenes on a Windows PC – perfect for sharing scans with clients, reviewing deliverables and showing projects in meetings. CoViewer is optimised for handheld scanning data and complex indoor spaces.
