Hello everybody! I'm looking for some good software or programming language suitable for creating some sort of animations aimed to didactic exposure of scientific topics. What I want to do is an application that allows to interactively follow the evolution of a star's internal structure. The idea is to have cross-sections of the star with colour-coded diagrams that describe time-varying quantities as temperature, density, etc... Some of the languages/softwares I was thinking of as suitable for this are VisualBasic, flash, xml... maybe some Abobe software... But I have no real experience in this, so I was looking for some help. I'd like to use something that offers both visual appeal and some scientific "rigour"... As an example: I want to realize a schematic view of the internal structure of the star as concentric annuli, which color changes as a specific function of time during the animation... Also I'd like to make this a little interactive for the user, with the possibility to choose the type of diagram or quantities, and arrange multiple diagrams on a page. If possible, I'd like to make this application compatible with web visualization. Now, I realize these are a lot of requirements. Any suggestion will be appreciated. If you could also suggest useful books or documentation, that would be great. Thanks in advance!
