After having read some of the posts on the forum it appears that ray casting is broken. However, in the vain hope that it's just me making a mistake can some one give some example code on how ray casting is used?

Here's how I'm doing it:

and the values returned are all zero. I've used Newton physics for some time now and it may be slow but at least it worked!


Please excuse my stupidity, the get pick vector commands are already unit vectors (if the distance into the screen is set to 1) and are not (as I thought) global positions. I changed the code to the folowing and it now works fine.

Sorry for the useless thread.
