incorrect geometry with scenejs-pycollada json files

[Benjamin Drucker]

I'm having trouble with scenejs-pycollada.  This is the plane rendered from the JavaScript data here https://github.com/xeolabs/scenejs/tree/V2.0.0/src/examples/seymour-plane:

Here is the json output of the latest scenejs-pycollada using the dae.zip from the same location as above.

I used the version of scenejs-pycollada at https://github.com/rehno-lindeque/scenejs-pycollada.git.  At first I couldn't get this tool to run.  I made the following change:

index b391505..cd11a89 100644

--- a/translator.py

+++ b/translator.py

@@ -492,10 +492,10 @@ def translate_camera(camera):

What is going wrong, you think?

I see similar odd triangles with several other collada files I pulled and converted from the Sketchup warehouse.  This model is not unique.
