Hey guys,
I'm using the example Surface_mesher/mesh_a_3d_gray_image.cpp in order to triangulate some 3D images.
Apparently, there are problems when the images get to large. I have generated a test image and tried to apply 'mesh_a_3d_gray_image' on it:
./mesh_a_3d_gray_image
zlib error: data/test.inr: requested length does not fit in int
_readImage: error: invalid data encountered in 'data/test.inr'
The image has a size of 2009 x 2009 x 400 voxel.
I have uploaded all data that you need to reproduce the error: https://www.dropbox.com/s/ki5vfqivj1qnsxs/data.zip?dl=0
Can you help me? I assume that more people would like to triangulate large images :-).
