I just discovered webglearth.com, which is similar to osmgo.org. Both 3D renderers are open source web applications that have been in development for many years. These renderers can help us understand data in new ways. Each differs by what is rendered and by navigation style.

In WebGL Earth, 3D terrain is visible on the globe after zooming in. A click and drag moves the camera along the ground. Along with two modifier keys, the Alt key rotates the camera from a fixed position to allow looking around, and the Ctrl/Shift key rotates the visible surface about a fixed distance to allow orbiting.

In OSM Go, every building, tree, fence, utility pole, hedge, etc. is rendered as 3D. Selecting an object will display info and tags for that feature. Moving along the ground is possible with arrow keys. Holding shift allows looking around. Additionally, PgUp/ PgDn moves the camera up/down.

Neither project overlaps with the other. WebGL Earth considers a holistic reality by animating the earth. It has the potential to provide APIs for showing interplanetary trajectories. Meanwhile, OSM Go renders every urban cartographic feature, including underground ones. Its interactivity feels like the precursor to a Sims-like garden and floor plan modeler.
