iraspa

iRASPA is a visualization package (with editing capabilities) aimed at
material science. Examples of materials are metals, metal-oxides, ceramics,
biomaterials, zeolites, clays, and metal-organic frameworks. iRASPA leverages
the latest visualization technologies with stunning performance. It can
handle large structures (hundreds of thousands of atoms), including ambient
occlusion, with high frame rates.

iRASPA is provided by David Dubbeldam (University of Amsterdam), Sofia Calero (Eindhoven University of Technology) and Thijs J. H. Vlugt (Delft University of Technology).
