So I'd have to snap my data to the grid manually? There is no way to convert a unstructured grid of points to a structured grid? (where it automatically sets the spacing to the largest spacing that will make each point fall on the grid?)<br clear="all">

You could assign the pixel values by whatever method you want. A simple<br>
test case can be generated by using the calculator on above image in<br>
paraview. (write it with a vtkDataSetWriter...)<br>
