Hello,
I am a new plplot user and I am not an expert of this tool.
I am developing a tomographic application to reconstruct the zones, of a
certain volume, where a certain substance is concentrated.
So I have a function defined on a three-dimensional space
h(x,y,z)
that gives the concentration at each point (a 3D histogram of the
concentration).
I want to plot it in a 4D plot with these characteristics:
- the plot space should be divided into voxels.
- each voxel should be colored following a palette, with a transparency that
decreases with the raising of the concentration.
How can I do this?
I tried to look in the documentation but I found just an utility to plot a 2D
histogram (exempla gratia a 3D plot of a surface over a cartesian plane).
Thank you in advance,
Cristiano
