[vtkusers] 64bit indexing problem with vtkImageData

[Jim Geach]

Dear list, 

I'm trying to volume render data cubes with typical sizes of >(3000x3000x3000) (these are outputs from a cosmological simulation). 

Currently I'm using VTK v5.4.2 (built with the 64bit indexing turned to "ON" in the CMake config). Everything seems to be going okay until it comes to the volume itself, or rather, the ImageData - I'm getting a crash with error like:

ERROR: In /install/OCF/software/vtk/5.4.2/VTK/Filtering/vtkImageData.cxx, line 2117
vtkImageData (0x72cacd0): Coordinate (1279, 1279, 719) out side of array (max = 4194303999

I read somewhere about 64-bit indexing not being properly implemented in vtkImageData, even in relatively recent VTK versions -- is this the case for version 5.4.2, and if so is it fixed in the latest version?

On the same note, I should note that I'm using VTK via the Python binding, and converting numpy arrays into vtkStructuredPoints. Will VTK just figure-out that 64-bit indexing is required when i do this?

Thanks, Jim
