[vtkusers] vtkLookupTable with vtkStructuredPoints or vtkStructuredGrid : How it works ???

[Lisa Avila]

Hello,

I am not sure what method you are using to display your structured points 
data set. Once you threshold to get a structured grid you have a lot of 
primitives - perhaps when you display the structured points you are 
rendering only the boundary and with the structured grid you are rendering 
all cells? That would cause a significant slowdown. Also keep in mind that 
the first render may take longer than subsequent ones when immediate mode 
rendering is off  (display lists are being used) - this is the time to 
build the display list.

If you only want to render the boundary there are filters you can use to 
extract that. If you want to render all the cells, then you should consider 
using volume rendering on the original structured points.
