Preparing for BVH

Step One : Hit a Box Square


Silly Error # 0: Not checking all necessary boundaries:

I forget what caused the speckled/noisy consistency. I think I was making normal t values negative, which later caused me to disregard them...

Success:

The slight distortion is correct because the eye is at (0,5,2). +Z is up.

Step Two: Hit a Box

Silly Error # 1: Checking wrong Axes-

Silly Error # 2: Adding negative signs to t value for the...fun of it.

Finally successful:

I chose to shade according to axis. Faces with a normal parallel to X got red, Y got green, and Z got blue.

I was worried that I was missing the sides, so I changed the eye position to (3,5,2). This verified I was getting all sides.
