Compared to brigl, buildinginstructions.js currently lacks a nice semi-realistic renderer. I know Nicola has spent a lot of time making the one in brigl where rounded parts look almost as if there are no transitions between polygons. It is on my list to come up with a nice one for buildinginstructions.js, but currently I can only offer the flat shader which looks similar to how LEGO makes instructions.
