At the moment I need to convert all my IFC files into Collada format to visualise them in Three.js. Is there any IFC Loader in three.js? I could not find anything. Is there any plan to develop an IFCLoader in the near future?
How difficult it would be to write that?
May be a late answer for this question. Have you seen the BIMserver plugin to get a three.js export of your IFC file? Check it out from here
