Here is something to think about. How about if areas in the scenery files can have seasonal and cultural info attached or embedded? If we try to implement seasonal textures it cannot be simply location based. If I hop into a real aircraft right now and fly from Johannesburg to Cape Town the scenery will be green when I leave and brown and dry when I land. Cape Town has winter rainfall and Johannesburg summer rainfall yet both are in the Southern hemisphere and only 2 hours apart. So how about : materials.xml contains seasonal materials like <material> <name>GrassCoverSummer</name> <area_attribute>USA</area_attribute> <season_attribute>Summer</season_attribute> <texture>Terrain/USA-green-grass.rgb</texture> <area_attribute>Europe</area_attribute> <season_attribute>Summer</season_attribute> <texture>Terrain/Europe-green-grass.rgb</texture> </material> <!-- *********** --> <material> <name>GrassCoverWinter</name> <area_attribute>USA</area_attribute> <season_attribute>Winter<season_attribute> <texture>Terrain/USA-brown-grass.rgb</texture> <area_attribute>Europe</area_attribute> <season_attribute>Winter</season_attribute> <texture>Terrain/Europe-snowy-grass.rgb</texture> </material> <!-- *********** --> <material> <name>CityCover</name> <area_attribute>USA</area_attribute> <texture>Terrain/USA-city.rgb</texture> <area_attribute>Europe</area_attribute> <texture>Terrain/18th-century-city.rgb</texture> </material> ---------------------------------------------------------------- Then we have a database of points that store the locations of cities or countries or continents with attached info. The points have info like : MaterialAreaType=European MidSummer = date x MidWinter = date y ---------------------------------------------------------------- Then when flying over Paris flightgear finds the closest point in the "points" database. - It finds that it's Europe (or France or Paris) - It's winter So it looks in materials.xml for GrassCoverWinter and an attribute that says it's Europe and pulls out Europe-snowy-grass.rgb The same applies for the "European 18th century city" texture. If no matching area is found then it falls back to standard textures. Having a "points" database means we can start on the macro scale like define a single point for Europe and then later on we can scale it down to countries, provinces and cities. Ok this is just a rough idea what do ya guys think? Paul P.S. Oops that took a few more lines to explain than I anticipated. :P _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
