Sorry for the late reply. The geoportal can be accessed at 3d.torun.pl and requires (of course) a browser and a graphics card with webGL support, and it's best viewed at Chrome or Opera (thanks to webp support). If your system does not support it the system falls back to a standard 2D maps geoportal. In 3D view in the lower right corner of the screen you've got 3 presets of combintation of visibile layers - LiDAR cloud point, symbolic 3d map, and textured 3D models. I'd be happy if you let me know what you think.
