[Bf-committers] Geospatial Blender
Hi All, I am currently studying libre geospatial tools such as QGIS and GRASS, at community college in Nevada City, CA. http://qgis.org http://grass.fbk.eu/ I would like to figure out how to use Blender3D for geospatial analysis and visualization. For instance, there is a nation wide survey of elevation data, in the United States, called the National Elevation Dataset (NED). I would like to take some known terrain data (from NED, LIDAR scans, etc.) and distort a Blender3D primitive (such as a grid) to simulate the terrain. This would open up many doors such as watershed simulation, fire simulation, city planning, game development, etc.. There are several file formats involved in geospatial systems, most of which are already handled by Python GDAL/OGR. I think that my proposal is to integrate these tools into Blender3D via the compositor, game engine, or some other means. The compositor seems like a strong candidate for geospatial process modeling. http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=An_overview_of_ModelBuilder I appreciate any feedback and/or mentorship that members of this community can provide. Would this be a worthwhile GSoC project? Thank you for your time and consideration. --Brylie Oxley ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

Hi Brylie, Blender is not intended to be analysis tool for all possible graphics related tasks, that said you should understand, that it is not Blender major point to move in a direction you describe. While, on the other hand, you may load geospatial data and edit it in Blender, and perform some simulations and it is very much welcome. but overall, there are more appropriate ways to perform geospatial analysis and visualisation, than to use Blender ( see http://en.wikipedia.org/wiki/GIS_Live_DVD OSGeo-Live DVD to get idea of existing opensource geospatial visualisation softwarehttp://osgearth.org/ ) Regards Sergey On Sat, Mar 17, 2012 at 2:08 PM, Brylie Oxley bry...@gnumedia.org wrote: Hi All, I am currently studying libre geospatial tools such as QGIS and GRASS, at community college in Nevada City, CA. http://qgis.org http://grass.fbk.eu/ I would like to figure out how to use Blender3D for geospatial analysis and visualization.

Hi Brylie, take a look at there tools http://vterrain.org/Doc/Enviro/overview.html http://vterrain.org/Doc/VTBuilder/overview.html from http://code.google.com/p/vtp/ and http://osgearth.org/ and use Blender to develop buildings, terrain feature elements etc, which you can load in mentioned tools.

All you need to do is convert the data to a bump map distortion or normal map and apply that to a subsurfaced mesh grid Check out Andrew Prices' video on making asteroids to lean how that is done. I also used Pand3d to play with this sort of thing. The physics can be done to with the game engine or other sim tools in Blender. Getting scientific data back out is not something I have played with but I have seen a tidal-wave simulation through a city somewhere and a building collapse done with Blender, so it can be done. Here is a shot I did using Crystal Space. This is the northern end of Flathead lake MT USA. http://code.google.com/p/perspectiveproject/downloads/detail?name=PerspectiveProjectScreenShot.png#makechanges Note date may 2007. It has been a long time and I am sure it can be done much better now buy someone with the time and skills to do it. I wrote a short python script to change the data to the data types I needed for the game engine and I have used the same data in blender as a normal users (no programming at all). Not to sure why the others or so closed to the idea, perhaps there linked tools really are the better way to do. I would not know anything about those other links or the science use of it all. If you know the government data format, Blender's data format and Python, you should be able to pull this off in about 1 hour or less. -- Douglas E Knapp Creative Commons Film Group, Helping people make open source movies with open source software! http://douglas.bespin.org/CommonsFilmGroup/phpBB3/index.php Massage in Gelsenkirchen-Buer: http://douglas.bespin.org/tcm/ztab1.htm Please link to me and trade links with me!
