Do you need to see the whole mesh, or only part of it? When rendering, with ANY 
renderer, you almost never need the full precision data set. You are limited by 
the pixel size and number, and any precision that result in sub-pixel changes is 
normaly unneeded.

If you see it all, then, reduce the number of nodes by 100 to 10000 times, or 
even more. Reduce the numerical presision, you quite probably don't need more 
than 2 or 3 decimal places. In this case, you can get several triangles per 
pixel, even after dividing their number by 1000...

If you only see part of it, look if you can get subsets. You then only read 
those that are going to be rendered.
Even here, you can surely reduce the numerical precision down to about 4 or 5 
decimal places.
