matteopaternolli Posted February 17, 2012 Report Share Posted February 17, 2012 (edited) Hello,I have a DEM file, and I would like to create a mesh from it. I imported the file as scatter points and then I filtered the data with the filter angles option. Then I made the triangulation, but in some areas I still have a huge amount of triangles, with elements connecting all the points of the DEM. How is it possible to create a coarser mesh, with bigger triangles? I would like to have an interpolation during the triangulation process, not only a connection of the scatter nodes…Thank you very much!Matteo Edited February 17, 2012 by matteopaternolli Quote Link to comment Share on other sites More sharing options...
Rusty Jones Posted February 17, 2012 Report Share Posted February 17, 2012 Hi Matteo,What you should do is use the map module to create what we call a conceptual model to specify where the nodes should be placed. Then you interpolate the data from the DEM to the nodes.You can read the values in as a raster. A raster will keep all the original points (there is no filtering). However, it is managed in a way that allows more data and will display faster than the same data as a TIN.If you look at the tutorial labeled overview, it goes over a little bit about crating a mesh using a conceptual model. Try working through it to help. If you read the DEM as a raster, choose raster as the bathymetry source when doing the map->2d mesh. Quote Link to comment Share on other sites More sharing options...
