PS : to reduce aliasing (visible on some parts of your helicopter), one 
simple effective technique (in addition to parameters like +a0.0 +am2 
+r3 ...) is to render the picture on a larger size, and then rescale 
with some image manipulation tool. Usually, render time is not a problem 
with this kind of picture, so it is possible to render very large images.

>> Hello everyone!
>>
>> I've created another Lego colouring page based on the Police 
>> Helicopter set 645.
>>
>> This image was created using a combination of MLCAD, LdrDat2Dxf (by 
>> Rolf Redford), PoseRay, POV-Ray 3.6 and the PovEdge macro (by Thibaut 
>> Jonckheere).
>>
>> I created the black and white image by setting all the objects to 
>> white, and then used the "outdoor radiosity" option from PoseRay. I 
>> had to add a couple of extra light sources to saturate the image with 
>> light. I had some problems trying to maintain the transparency of the 
>> windscreen, but happy with it for now (I'm not sure how the PovEdge 
>> macro copes with transparent objects - perhaps I need to do some more 
>> experiments).
>>
>> Does anyone have any other tricks for creating these kind of images 
>> (i.e. rendering shape outlines of 3d objects)?
>>
>> You can download printable PDF's and other 3D model formats, including
