Regular grid to arbitrary grid interpolation

[ApplestarGY]

Hi,

I need to interpolate a 3D array from a regular grid (orthogonal, and equally spaced in each dimension) to an arbitrary grid. Is this interpolation feasible using this tool?

Thanks,
Yuan

Hi! Unless I misunderstood the question I don't think so. This package does affine transformations in GPU texture memory: constructs transformation matrix, then applies it for each point in the resulting volume and then finds an interpolated values from the original volume.
