cornell works, but...

[fogleman]

I use "go run examples/gopher.go"

It's looking for relative path "examples/gopher.obj", not "gopher.obj"

Hi,

When trying the examples, the cornell box works fine:

...t/pt/examples% ./cornell
Building k-d tree (8 shapes)... OK

[Iteration 1 of 10]
512 x 512 pixels, 1 x 16 = 16 samples, 4 bounces, 2 cores
44 / 512 ( 8%) [=== ] 0:00:02 1.0M ^C%

However, the cube fails:

...t/pt/examples% ./cube

So does the gopher:

This is on 64-bit Arch Linux, kernel 3.18.6, go 1.4.1.

Wonderful project, btw!
