How can I plot a colored, 3D nonuniform surface (with a hole in the middle) with 4 vectors, containing x,y,z-coordinates and a pressure value for the color.

I would like to plot the pressure on a nonuniform surface through a steam-turbine (so it also has a hole from the blade). Therefore I have four vectors containing the x,y,z - coordinates and the pressure value.

The closest I got so far was a cloud of colored points by using the patch function.

However what I want is a filled contour plot like this:

I already tried all the surfs and mesh methods and griddata, unsuccessfully. I also tried to create a surface with Delaunay Triangulation. What I got was this:

I would be grateful for new ideas.

Hello,

I am just wondering if you have found any solution to your question. I am plotting 3 coordinated + Weber number and I would like to have a continuous intrapolated Weber number in the free surface represented by the 3 coordinates.

Many thanks in advance.

Can you use delaunay to create triangles (triangulate) and then to remove long edges (and triangles)?

Delauny does not lead to a satisfactory result. However, I was able to export the mesh information and then use the patch function. Then it works like a charm.
