I haven't tried it yet, but you need to make an improvement in your website. It took me a while to figure how to download it.
What about the huge "Download" button on the home page ? Couldn't be easier I think.
OpenCL could be an interesting route too. I suppose one of the bigger problems Gephi is facing is calculating the positions of the nodes while keeping the data on the GPU? (This would map very well to OpenCL since you can share buffers between GL and CL
Yes I agree, calculating the positions of the nodes, called "Layout" requires a lot of computation and using GPU could help a lot, as explained in this article (A. Godiyal, J. Hoberock, M. Garland, and J. C.Hart. Rapid Multipole Graph Drawing on the GPU. In Graph Drawing, volume 5417 of LNCS, pages 90–101. Springer, 2009.). Your demo is impressive. So if I move to JOGL2, which is in the task list, I could use OpenCL with ease ?
Is it possible to use it in an Eclipse RCP application too? It seems very interesting
Well I don't think so. Go Netbeans dude !
