    In the screenshot album on at BrlCAD home, there is "Puget Sound rendering screenshot".  Trying to track down how this was accomplished in BrlCAD has resulted in several dead ends.  I have a GIS rendition of the area (several different formats, actually) I am interested in, and have also digitized this (55,000+ xyz points defined).  Now I would like to use BrlCAD to create a solid surface from the map or the digitized points (ultimately to do water flow studies).  Does anyone know how the Puget Sound rendering was done?

    I saw this as well and I thought to myself: "Man, that is so cool!" I mean. this is going in a direction completely different from the core engineering analysis and rendering of mechanical components/assemblies that BRL-CAD is known for, doesn't it?

    I'd be interested to learn how this Puget Sound stuff was done myself. I will most definitely keep an eye on further developments in this regard.

    Actually, my goal is to build a mesh for a CFD analysis of tidal currents in a channel- so it is not all that far from "completely different from the core engineering analysis and rendering of mechanical components/assemblies that BRL-CAD is known for…".  I see additional applications for studying flood basins, etc…

    Ahh! I see your point.

    Basically you're applying a paradigm that is more geological, rather than strictly mechanical, in nature. Correct?

    Actually, we will be getting back to the mechanical part eventually…The big picture is ocean tidal energy conversion, but I can't find anyone willing to put up the quarter million dollars needed to do a full, real-world analysis.  So, maybe if I can model it and demonstrate the potential, I can get people to listen to me.  I have six other sites to evaluate as well, if I can figure out how to get the bathymetry data I have extracted from GIS software into a proper mesh…

    Very interesting indeed.

    I've been looking through the rest of the forum for any other threads you've may have posted, but haven't found any. I wanted to know a little bit more about you, along with whatever organization you may be a part of; I noticed you used the word "we" and that you're looking for some serious cash. :)

    So, if you'd like to present some more information about yourself and any organization you may represent, It could help me and other members, as well as the BRL-CAD developers in particular, understand a bit more about what you're trying to accomplish, if you haven't done so already elsewhere.

    I am a power systems electrical engineer myself, primarily in the mining and industrial/utilities sectors, so I look forward to learning more about your plans; perhaps there are some ideas that might be applicable to my field as well.

    Thanks.
