I’m comming from the http://www.openstreetmap.org community, that creates a free wiki worldmap and offers even it’s datas under a CreativeCommons license. Currently we have a growing number of buildings and of course already some tools doing simple 3D presentations out of it.
But of course we want more details and so we thinking about a spin-off project that implements a 3D model reposity.
Even if I used Blender3D for years I have not much experience in 3D file formats and we have currently the problem on deciding which format to use. Google Sketchup uses Collada and so why we should reinvent the wheel?
Honestly, to me COLLADA looks pretty complex and I’m not sure if it fits for our usecase:
-allow every user it’s fav. editing tool
-make georeference easy, idealy embedded in the file
-be flexible to let other projects use our resources, too (e.g. for flightsims,…)
-let model any kind of buildings (houses, bridges, towers, …)
-let model even Points of interests (fountains, wind generators, power poles,…)
What might be useful in later steps:
-flexible align/position relative to other things (e.g. traffic light looks along a road)
-generalisation (common objects e.g. a common bus stop for New York)
-state depended (day,night, details basing upon attributes)
So what does professionals say, is it the right task for COLLADA?
