Visualize BIIIG data

[anjohn]

Heyho,

I'm working on my master thesis and it is about Delaunay-Triangulation. Now I have a huge set of triangles in 16384 files. A small number of files can be rendered with QGraphicsView and QGraphicsScene:
triangulation.jpg
Unfortunately 1000 of these files take more than 1GB of memory.

Do you have any smart ideas how to visualize all files at once?

I realized that I need to convert each file into a QPixmap. But I think there might be a problem: Each file doesn't have a straight scene rect, there are allways small noses at the edges because the points that were converted to this triangulation don't lie on a grid! In fact if I combine a number of pixmaps, I get some unpleasent white stripes between both pixmaps.

I don't know how to explain it better ... sorry!

Anyone an idea?

Thank you!

best regards,
anjohn

Or is it better to create 1 image or a few images that allow the user to see an overview and then drill down?

Would be nice but I cannot create one image because loading all 16384 files would take more than 16GB of RAM. I allways can convert just a small number of files into an image.

I think I have to build one image by combining several images ...
