We did background check on what vtk is all about and what are the scopes of creating a useful application using this toolkit. We took up the project when we had enough resources and information for our design. But all the credit goes to our mentor Mr. Anupam Agarwal who suggested us the topic as well as guided us.
Visualization Tool Kit:
It's a toolkit which can be imbedded with c++ on windows i don't know if its available for other plateforms but i read it its' plateform independent so i guess there must be ways to run it on various plateforms. It has many inbuilt libraries which makes the work of a programmer very easy. For example if you will write a programme for 3-D cone which interacts with user . It would be pretty lengthy using open GL since they use basics for this but here its hardly few lines. So for creating bigger apps you don't have to worry about minute details.
What we have thought of designing is a medical utility as a coloured x-ray so that a portion of the body can be seen in different colour which can be a breakthroug in medical science. We have though of taking up a software approach.
