Yes I did change that and nobody noticed until now!!!

I don't remember why I made the change exactly (it was several months ago--during intensive Manta development which was happening at SGI ) -- might have had to do with precision in the Double Eagle model which has a lot of long range views--just a guess.

This was about the time of the first Newport News demo.

May have had something to do with shadows since this was the introduction of the headlight.

(btw e-4 to e-3 is a "little" change ;-) )

You changed the T_EPSILON value from 1.e-4 to 1.e-3 without even mentioning it in the commit message:

"Big change: Added computeLight method to Light. Added HeadLight class. Parallelized kdtree load, is now around 3 minutes, down from 10. Only triangle parse is parallel, io takes a while still."

What was the reason?
