Hello,

Is it possible in new version to project a mesh on a plane? or is there alternative methods?

thanks,
Jules

got it! Thanks Daniel

Hi all,

I try to export a DEM from a point cloud using the rasterize tool, together with the height std dev and other scalar fields.
I can find the height and the scalar fields in the output raster, but impossible to see the height std dev. Is there some trick to get this or is it a bug?

cheers ...

From your posts I got ideas and I found a trick that does the job. You need to cut a vertical band of the core (cylinder) in order to unclose the mesh. The location of the cut is important, so make different tries to find the good one.
For our needs this will be good enough even if it's a little ...

so maybe images are clearer to explain what I obtain :

original mesh with texture : core1.jpg

unrolling previous data with cylinder gives : core1_meshtexture_unrolled.jpg
observe the strange horizontal lines in the left and bottom part of the image
I precise that I tried with different radius ...

thanks very much for the quick answer,

I don't feel ready to code this function but I'll try your suggestion with big amount of point and remeshing.
Our goal is to make visual interpretation, and if possible image processing, on the unrolled core (fossils, fractures, facies, ...), thus we need ...

Hi,

I have a textured mesh (geological core) that I wish to unroll.
The tool Projection/Unroll works well for point cloud, but produce weird result when unrolling a mesh or a textured mesh.
Is there any tip I am missing here?

thanks in advance,
Jules
