Visualization of large astrophysical simulations datasets

The baseline technology is the object-oriented programming offered by IDL’s Object Graphics [3]. The interface is implemented as a graphical widget providing interactive and immersive 3-dimensional navigation capabilities. The user acts on the objects attributes through an ensemble of menus, drop lists, buttons and dialog fields. Complex objects such as isosurfaces are implemented as polygon and polyline objects with the help of optimized procedures of the IDL library. Visualization of 3D objects benefits from the implementation of light objects that represents sources of illuminations. SDvision
