Hi,
I want to display heatmap contours of a variable on my point cloud surface geometry. To do this I imported the point cloud file and then opened the CSV file that contains the point cloud file’s vertices coordinates and their variable values. Then the TableToPoint filter is applied and at the end, the SPH dataset interpolator is used to interpolate the variable values to each vertex on the point cloud surface. However, I noticed that the variable values after applying the SPH dataset interpolator depend on the spatial step. The larger step, the higher values of the variable, which is not what I am looking for.
Furthermore, the obtained heatmap contours seem to be different and somewhat inaccurate compared to the TableToPoint contours that are displayed on vertices.
I would be thankful if you can look at the attached point cloud and the CSV files. Many thanks in advance.
