Spherical Cube Map rendering library

Spherical Cube Map Rendering

Copyright © 2011-2014 Robert Kooima

SCM is a C++ class library that implements a rendering engine and non-homogeneous data representation for the interactive display of spherical data sets at scales of hundreds of gigapixels and beyond. Applications include panoramic image display and planetary rendering. The SCM data representation enables out-of-core data access at real-time rates. The spherical geometry tessellator supports displacement mapping and enables the display of planetary terrain data of arbitrary resolution.
