1 Eyes vs Cameras

1. Move the film out in front of the pinhole, so that the image is not upside down
2. Only render (compute an image for) objects further away from the camera than the film
3. Add a back clipping plane for efficiency
4. Volume between the film (front clipping plane) and the back clipping plane is the viewing frustum (shown in blue) •Make sure near/far clipping planes have enough space between them to contain the scene •Make sure objects are inside the viewing frustum •Do not set the near clipping plane at the camera aperture!

Cameras Distortion depends on Distance

• Do not put the camera too close to objects of interest!
• Significant/severe deductions for poor camera placement, fisheye, etc. (because the image will look terrible)
• Set up the scene like a real world scene!

Eye Distortion?

1. Your eye has the same distortion, or even worse because it has slightly curved “film”

2. Unlike a camera, you don’t actually see the signal received on the cones

3. Instead, your perceive an image processed by your brain

4. Your eyes constantly move around obtaining multiple images for your brain to work with

5. You have two eyes, and see in stereo, so triangulation can be used to estimate depth and undo distortion

6. If your skeptical about all this processing, remember your eye sees this:
