object3D.setShadingMode(Object3D.SHADING_FAKED_FLAT) doesn't change anything, shouldn't it?

How do I get shadows of my single light on other triangles?

I have some objects of triangles with a plain grey color texture, one ambient and one point light. I would expect to see the triangles in one static color, but it seems there is a lot of smoothing or whatever going on. Can I switch this off an how?
thanks

I think relative to absolute coordinates somehow were to small. I scaled everything by 1000, then moved everything so that the first point is origin. Now I see it   

I read somewhere about points being collapsed, can't remember where and there must be a minimum?

There seem to be minimum dimensions. A Primitives.getSphere is not shown when the "scale" is smaller than 0.5? I didn't see something like this mentioned anywhere.
Btw. in the doc it is not told what the "scale" parameter means.
Or are there minimum camera distances etc?

For days I am now trying to show small objects (scale 0.05 range) and I don't get to see them ...
Can the world be scaled altogether or something like that? Or do I have to scale all my objects?


... ok ... now I adjusted Config.nearPlane  AND(!) set Config.glIgnoreNearPlane to false, so I see something. But apparently many points collapse, so where do I set this? Can I?


EDIT 2: My coordinates are about in a range of 50.000 to 50.010, is something like this possible or do I have to move everything to center it around the 50?
