36 pieces and almost there. [1]
A little test with the explosion view model, not yet animated.[2]

Still some modeling to do then fine tuning scaling, positioning, colours and coding.
It will be busy days.

Already or just 3.6mb.

By using the bump map technique from animation and game modeling you can simulate the thread without getting a huge file size. This is how the pieces look in the browser.

On exporting from Sketchup Sucks:

I export them as .dae (collada) but the mesh is a mess.

- usually the models consist of countless, unnamed groups ( I don't like to work with cluttered drawings ) - double vertices ( these you can remove easy with Blender ) - unconsistent normals directions ( these you can't always recalculate automaticly with Blender ) - holes in the mesh

Sometimes I use them as a reference to redraw them in Blender.

I'm working on assets for the webGL interactive models wich is more of a game approuch to modeling so I'm focussing on that. Sinds it is a architectural project we should have the assets also in a Open Source CAD format if we want people to start using them to design houses with BIM. I think.

In FreeCAD you can then export in .ifc wich is a open BIM format that people than can use in other applications if they choose. If a whole house is exported in .ifc it can then be converted into xbim that can be watched in a browser, also offline, wich is low treshhold for everybody.

A brief explanation of webgl.

Programming in native webGL is a bit devious.
By using javascript libraries it makes things a lot simpler.
-three.js [3] /
-babylon.js [4]
-sceneJS [5]
-etc...

Why three.js?
Qgis [6] (Open Source geographic information system) and Blender [7] (Open Source 3D modeling suite) have a three.js exporter plugin [8] [9].
Three.js has loaders for other 3D formats so you can make something in other OS 3D software and load them too.
It's combinable with other javascript libraries like:
-dat.gui.js [10] (GUI for changing variables in JavaScript)
-physijs [11] (Physics plugin for Three.js)
-etc...
It's Open Source and free (MIT license).

Working on 3D webGL framework for OBI http://3dcontent.be/ecohome/ecohome.html -I still have to decouple the camera control from the explosion view slider. But how do you do it when using the htmlmixer.js???
