Dear Group,
ListContourPlot3D can be excruciating slow when trying to construct a 3D
image out of a series of (say 40 to 50) high resolution 2D (512 * 512
matrix) images. Can someone suggest an alternate strategy for handling
these types of data sets.
As a short example, take 10 4x4 images.

testdata = Range[10*4*4];
twoDimages = Partition[Partition[testdata,4],4];

You can use Raster or ListDensityPlot or ListContourPlot to look at each
image.

e.g. ListDensityPlot[twoDimages[[1]], Mesh->False, PlotRange->All]

will give you a 2D image of the first image in that set of which there are
10.

I want to put all these images together as a 3D volume. ListContourPlot is
what I have found and with large data sets it is really really slow. What
are my options?

Thanks
Yas
