Globe for Google Cardboard - experiment
This experiment renders an orthographic globe of the world on two canvas elements, creating a stereoscopic 3D effect for Google Cardboard. Using D3 v3 and TopoJSON, the visualization loads world land topology and draws the globe with a steelblue ocean and dark green landmasses. Two canvases render the same rotating globe from slightly offset angles, simulating left- and right-eye perspectives for use in a Cardboard viewer. The globe continuously spins on a timer, and the projection’s rotation is updated incrementally to create animation. The side-by-side canvases are intended to be viewed through a Google Cardboard headset for a 3D experience, though the code does not implement the barrel distortion or lens correction typically required for a true VR view.
