I want to make a project in iOS, which will show 3D images of objects ( like in my app 3D image of bike or car, so everyone can see bike from all sides and directions).
So I am making It in XCode, in XCode I need .dae file for 3D images, So how can I use sketchup framework in xocde and make those 3D models in XCode.
The SketchUp SDK contains an interface for reading and writing .skp files in external applications, as well as for writing binary importers/exporters for the SketchUp application itself. Since the SDK’s source is not completely open, it is only available for the x86 architecture (32bit and 64bit).
I fear you won’t be able to make use of it if you want to deploy your app on a mobile device with ARM architecture. If you are just looking for a Collada file reader/writer (and don’t need the .skp format), you can certainly find many alternatives.
