mesh looks incorrect (threejs r68)

I'm using threejs (R68) on the model online view project which converts some uploaded models to threejs files. We found some models look incorrect as below.

mesh incorrect

Some models can be viewed at http://www.threedbook.com/detail/23981

Especially when move the models(rotate or pan), the mesh color and shade look changing all the time. Strange thing is that model will look normal if it's zoomed in enough size. Would anyone point me which causes the rendering problem? or any issue when I convert the models to threejs file?

Thanks a lot!

The modelling of the object is incorrect. You have overlapping polygons over the same area and very close to each other. When rendering, that would cause the appearance to change (specially if you are zoomed out since you dont have enough rendering resolution); ie. many polygons are squashed on top of each other and the renderer doesn't know which one to render first. When you zoom in, everything is ok because now you have the resolution.
