# canvas graphic output doesn't work [closed]

at the moment i'm developing a 3D-Vector-Coordinates-to-2D-Canvas-Calculation.
the code is ready, the canvas too, but something doesn't work right...
You can find my code at www.philip-maerz.de/game/enginetest/engine.js

I've posted my question already on computerbase.de, but there nobody could help me...

Greetings P.M.

• Hey PM, welcome to the site. Unfortunately these types of questions are not a good fit for the site. Essentially this is "Here's my code, where's my problem?". You'll need to narrow down the problem to a small section of code, try to solve it and it you can't tell us what the problem is, how you tried to solve it, and why it didn't work. See the FAQ about what types of questions to ask here. – MichaelHouse Oct 13 '12 at 15:44
• Well, that IS my problem. I tried to figure out where the problem is, but no one saw anything and the browser keeps saying: "script isn't answering"... I debugged it with firebug, until there was no more fault, but this failure continues... – Philip März Oct 13 '12 at 20:32
