CloudCompare forum

If I create an SF (usually by exporting Z) and drag the thumbs to set the upper and lower bounds, all works as expected.
If, however, I rasterize my cloud (e.g. 0.5m step, Z direction, average cell height, no SF interpolation, no resample input loud, but interpolate empty cells), there are problems with the resultant cloud.

Assuming I have an irregularly shaped area, my cloud first appears as a red shape with blue sections around the outside which together make a rectangular region. This is expected behaviour because the interpolation outside the cloud results in points with a zero Z. As an aside it would be nice to perform the interpolation only on a convex hull of the cloud. I understand there can be problems deciding what constitutes a convex hull.

I need to remove the zero elevation points and if I try to drag the slider, CC will crash. Of course a work-around is to type in a value for the lower limit that is somewhat less than the lowest elevation.

In fact the empty cells that are outside the convex hull are indeed replaced by the value which can be set just below the 'Fill with' field (0 by default).

Interpolating the cells only inside the convex hull won't be a problem (the convex hull is unique - it's the concave hull which is problematic). But it's just that this option as been added to create a 'full' raster with no holes.

For the crash, I can't reproduce it on my side. Do you use the latest beta version? If yes, can you send me the original cloud and a snapshot of the rasterize dialog (with all parameters set, etc.)?
