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?
Note:
Let consider 3D data to be visualized interactively, so rotation and selection (slicing) being available realtime.
