Awesome news! I’ve always been looking for something like this. I haven’t yet looked at the code, does the addon support saving the result to a file, too?
Also, I guess you’re using linear interpolation, not tetrahedral, right?

cool thanks @vvzen, hope it fits your desired use.

the example is not exporting any processed file. just processing live what you draw between begin/end but could be easy to add to your app.

sorry, but no idea about the used interpolation, maybe you can look into the source files I used, that are linked into the addon info.
