Are there any good 3D libraries/frameworks for rendering 3D worlds in geospatial coordinates on mobile platforms?
Use case: I have some known 3D geospatial features (eg. buildings) with their corresponding lat,long,elevation values as well as an underlying DEM. I would like to render such a "scene" from a given camera viewpoint on either an iOS or an Android device.
I could use opengl-es but it would take some effort to convert the geospatial coordinates to cartesian coordinates. Is there a "geospatial-aware" soft of 3D library for mobile platforms that I could use? Something like the AGI insight3D libraries but for mobile.
