How does it work?
Ok, can someone answer this with the patience and small words they'd use to explain it to a 6 year old?
Does it render the scene then calculate the view angles? Or does it do it from scratch for each eye? Or does it do some other sorta weird voodoo magic?
Cheers,
Ace.

- I'm not sure I understand what you are asking.
- Most 3d games render a single image from a single viewpoint.
As you move around the arena, your viewpoint changes direction, and position.
You are effectively moving a camera around the arena.
In a stereovision game, the game is rendered twice, once for each eye.
Before rendering, the cameras position is moved a little to the left, and the left view is rendered.
Then the cameras position is moved a little to the right, and the right view is rendered.
The 2 camera positions are simulating the position of your 2 eyes.
The small difference between the 2 camera positions creates the magic.
Both the left, and right images are displayed at the same time in the head mounted display.
Your brain does the rest.
