CloudCompare forum

Hi there dear CC-Community,

i am working on a vegetated dune. Data consist of point cloud, orthophoto, DEM. Somehow i have to mark the vegetation present on the dune. qCANUPO is not the best solution, as it should be clearly visible where vegetation is present.

So up until now i marked in Globalmapper in the corresponding orthophoto every plant as an area using polylines (tedious, but oh well), i exported all areas as *.dxf and connected it to elevation values from the corresponding DEM. This gives the polylines altitudes so i can load the dxf file into CloudCompare on top of my 3D M3C2 result.

BUT: only the lines are visible in CC and the area within is not filled with colour. I am able to change the colour of the outline, but how can i fill every "closed" polyline? Is it possible to do so inside CC? Is there maybe a workaround in Globalmapper (maybe i need to export from globalmapper to another file format?)

The picture makes it more clear what i want :) (did that manually in photoshop)

Greetings

If you need to color the 'inside' then you actually need a polygon, not a polyline. The easiest way to do that is to mesh the polyline I think.
Either in GlobalMapper if that's possible (and then export it as a mesh file that CC can support).

Or use CC's 2.5D triangulation tool. This might give you a polygon more extended than your polyline (if it's concave) but there are several ways to reduce it afterwards.

Hey Daniel,

thanks for the reply. It got me to the solution. Inside CloudCompare i was able to create a polygon from a polyline under "Tools - Projection - Contour Plot (polylines) to mesh". But it got the wrong result as shown in figure. Every option inside "Edit - Mesh" was grayed out when highlighting a polyline.
The solution was inside globoalmapper, where i could export wavefront *.obj files which CloudCompare is able to visualize. If the in depth Solution is wanted i can post it here. But it's no CloudCompare matter.

Thanks again for the reply!
