I am very new to SAGA but have gotten some good success using it for hydrologic modeling. Thank you for such an awesome free capability and hugely helpful forums.
However I am looking for a simple tutorial or advice for another common workflow that I currently execute with a collection of proprietary (and extremely expensive) tools: converting DEMs to .dae models for use inside Sketchup.
Is there a SAGA tutorial for doing something like this? The output could be either .dae or .ply as long as the .ply is ASCII (there is a working Sketchup plugin for importing .ply, but it only handles ASCII not binary).
My generic workflow is (assuming I'm using something like SRTM as a base to hand-craft models upon):
Identify and extract area of interest from SRTM cell
Convert to TIFF
Do whatever resampling I may want
Reproject to UTM
Export to TIN
Convert TIN to .dae or .ply (ascii)
Is such a thing possible in SAGA? I have done a fair amount of research on this and it seems that it's a bit of a unicorn. I'd be really interested in hearing from anyone who has conquered this.
(I am also aware of the Qgis2three.js plugin for QGIS - on my heavy-lifting work PC, this will not work as our policy has localhost blocked.)
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
both formats are not handled by SAGA (we have a Collada exporter in-house, but that is not of help here), but I think Sketchup should also be able to handle STL files. So a workflow could be:
...
5. TIN > Tools > Grid to TIN
6. Import/Export > Shapes > Export TIN to Stereo Lithography File (STL)

Maybe you like to give it a try,

Thank you Volker, I will give this a shot at home - at work, I use SAGA libraries that come with QGIS (2.14) and there is no Grid to TIN tool.
