Hi,
I have a set of all Coordinate Points (x,y,z) of my irregular shaped geometry and I have a set of data (xc,yc,zc,C) with C = value of interest. I want now to determine for every x,y,z of my geometry the value C.
I tried using but the results are not what i want:
[XXCoor, YYCoor, ZZCoor]=meshgrid(xc, yc, zc)
Cm = griddata(xc,yc,zc,C,XXCoor,YYCoor,ZZCoor);
scatter3(XXCoor(:),YYCoor(:),ZZCoor(:),4,Cm(:),'filled');
for illustration here is one picture with the datapoints x,y,z and one picture of plot what I tried. Like you can see the geometry is a facemask and i want C only on the facemask and not in the inner volume.
Maybe you can help me
best regards , Alex

I am doing the similar thing and just found your comment here. What are your px, py, pz in this case?

Sorry, but you cannot use tools like griddata or scatteredInterpolant to interpolate non-single valued relations. It seems all you have are a set of scattered points from some general manifold embedded in R^3.
You probably need to work with the surface, perhaps as generated from a CRUST algorithm.
