Sometimes it nice to have a little more context than blocky building masses when designing. Google Street View can provide this context, however it's usually open in a separate window and you only really get one viewpoint at once. So I thought it would be nice to embed Street View into the Rhino viewport, or at least enable one to grab multiple views in order to provide more touch points from the real world.
This work-in-progress Street View component for Heron uses a point(s) to query the Google Street View API. The API returns the closest Street View location, a slice of the panoramic image with the specified field-of-view, heading and pitch and some meta data. Grabbing the entire pano sphere is not part of the official Google API, so this functionality would need further development.
