Interpolate intensity graph

[HEAPO8]

I am trying to use the 4D Interpolation method within my programme, but I'm having some problems with incorporating it. I used the previous 2d bi linear interpolation developed by altenbach (thanks altenbach ) and it is working perfectly. I'm now want to test out the code developed by JRanalli. Can anyone help. That includes Altenbach (apologies-let by gones be bygones! )

I have never investigated quadlinear (?) interpolation in 4D, but I have made a trilinear interpolation for data in three dimensions. The link can be found in my idea here.

Do you really have 4D data? What are the dimensions?

Hi Altenbach,

I have put the 3D interpolation in my VI and I am getting readings. But they are coming out as plots- what I would prefer is to see my 2D bilinear data in 3D (please see an example of what i mean below- it hasthe 2d data transalated into 3D form. i did this with another piece of software). I'm thinking maybe the 3D Surface graph VI will do?  Are there any examples on how I can incorporate that into my program? Or maybe I can add colour to the VI (like the 3D Plot Merge VI). Any ideas? Thanks.

Hi Altenbach, any update?

[altenbach]

Sorry, I have no idea what you are trying to do now. What is the 3D graph supposed to show?

Your document shows two graphs. Some surface with three peaks at the bottom and some blobs in space arranged in a circle. Are these blobs supposed to be parameteric surfaces?

Hi Altenbach. Please ignore the circles. The 1st picture represents a foot with the colours representing the various pressures in 2D form. The 2nd picture is the same picture but represented in 3D form, with the higest pressures being a greater length than the pressures with lower temperatures.

I don't know if you've had a look at the VI I sent you? even though I am getting values it doesn't really relate to the 2D interpolation graph (for one, the scales do not go up to 5V and there is no colour code). Any ideas? Thanks
