Import in Blender, move origin to model, center it, then cut it to pieces. If stl or obj is the right choise, I really don't know, but Retopoflow is behaving a little better with obj.Įxport full area, reduce in MeshMixer, that does not worry about reference/anchor/pivot point. When using obj, it needs a 90 degree flip on the X axis. I have decided, that I am capable of lining up parts manually. It does give a better behavier, but not much. Upon import in Blender, I am now moving the Origin, to somewhere inside the model. The creator of Retopoflow, has looked at it and he says, that it is behaving strangely. Retopoflow and the Knive tool, are not working as expected. Erase & Fill, Reduce and Smooth are the tools I use. I am now using MeshMixer to reduce the mesh. I have found that Blender, does not like the mesh, that comes out from CloudCompare. There is a pretty fair chance, it will eat your file.īefore we start, a copyright notice needed for the data used.Ĭopyright notice Bellahøj Park Point cloud and Ortho photoĪs required, according to this site: (In Danish)Ĭontains data from Geodatastyrelsen and Danske kommuner Fot-dataĮkstracted lokation : Bellahøj Park CopenhagenĭLD 30/10-2015 Punktsky_617_72_LAZ_UTM32-ETRS89Įkstracted lokation : Nisseringen NæstvedĭLD 14/11-2015 Punktsky_612_68_LAZ_UTM32-ETRS89 It is Open Source and can be downloaded here:ĬloudCompare supports import of 27 different file formats. This is somewhat beyond the scope off this tutorial, but searching for geodata or height model, together with the country, should be a good starting point. Lidar is popularly used as a technology to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing, atmospheric physics, airborne laser swath mapping (ALSM), laser altimetry, and contour mapping.
Although thought by some to be an acronym of Light Detection And Ranging, the term lidar was actually created as a portmanteau of " light" and " radar". Lidar (also written LIDAR, LiDAR or LADAR) is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light. For creating the software and the pointers, that made this tutorial better. Ad to that, all the things you can do to those files.Ĭreated with CloudCompare 2.6.2 and Blender 2.76bĪ heartfelt thankyou to Daniel Girardeau-Montaut, the creator of Cloudcompare. There are so many purposes and ways to use LIDAR data, that we have acces to a forest full of free and paid for software, plus lots of file formats. Many frustrations.įinding the right way into LIDAR point clouds, is like navigating a dense jungle. This is to keep others from having as bumpy, a ride into this as i have had.
