I think svg supports more than just lines and curves, and you also want to be able to move the shape and resize it later. so a simple drawing is not enough. it could be converted to glsl though... I think blender has some kind of svg to gl conversion script. maybe that is a good place to start. they probably will be also the first ones to come up with a kml to gl script? external converter, luagl, pyopengl, or a native gem object, I don't know yet how to do it. marius.

hi, I am trying to get a good world map in Pd where I have separated countries. My initial idea was to be able to switch between a flat and a spherical view... that was probably too ambitious. First I wanted to work with the shapes of the countries, leaving the rest of the map black (for alpha blending), but that gave me some limitations when zooming in. Now I am reading into svg formats and how google earth handles location data and country borders (with kml files) and I wonder how I can display any vector graphics format in pd. at the moment I am converting from adobe illustrator to blender to wavefront obj. Is there an easier way to do that? I read that there are opengl libraries like cairo that can handle svg and draw them in opengl. otoh, with wavefront objects I have the problem that the countries are all flat and not bent to the sphere, so I wonder if that is solvable at all? I would rather stay with a flat map if I get moveable and resizable country shapes... thnx for hints! marius.
Hi, I don't think I can help you so much in here, but using svg files in pd is a good idea I'd like to exploit since I've seen how powerfull is vector graphic files. Wouldn't it be possible to parse directly with the textfile object the svg file and draw it's content?
