Often as a result of several simulations which are themselves intensive a huge amount of information i.e., points/line/plane depending to the subject of investigation are available. Although there are extensive list of multivariate analysis and data-mining techniques to summarize the results however I am often amazed by a simple visualization giving the most of the information in one shot.
Being familiar with some techniques in visualization e.g., application of OpenGL etc I would like to ask: 1- Is there any software/technique/framework/etc providing ability to visualize several million particles (points/lines/...)?
2- What is the most favorite application in the community of statistics? I'm not fan of R! What else?
Let consider 3D data to be visualized interactively, so rotation and selection (slicing) being available realtime.
