I am currently plotting a 3D geological model using point data on a scatter plot.
However the scatter is not square in geometry.
In order to plot surface planes between my points i am using the local polynomial method to create the surfaces between points of the same value.
My question is, how do you stop the surfaces being created outside the bounds of scatter data and creating a square shape and inferring the value of points outside my measured range.
Here is an image of my model, as you can see the isosurfaces extend outside the limits of my scatter plot, how do i set the scatter plot limits (which are irregular) as the bounds for my isosurface?
