[vtkusers] vtkImageData - vtkUnsignedCharArray: Unable to allocate 768951260 elements of size 1 bytes.

[Allie Vacanti]

The memory footprint of the input polydata isn't really important here,
rather it's the bounds of the input dataset that are determining the size
of the output in this example.

What's the value of the dims arg? That's what is ultimately determining the
size of this array.

>From the linked code, the final size of the output scalar array will be

(dims[0] + 2) * (dims[1] + 2) * (dims[2] + 2)

bytes for uchar scalars. You likely want to reduce the resolution of the
spacing parameters based on the input bounds to keep the size manageable.
