NASA World Wind for Java API Overview
0 likes2,844 views
NASA World Wind is a 3D API for rendering planets like Earth using data from NASA. It is based on JOGL and allows adding 3D objects and other data layers. The API contains classes for configuration, rendering, views, layers and controllers. It also includes demos for visualizing grids, shapes, images, and stereo views using anaglyph glasses.
