4. Texture gradients
5. Atmospheric perspective
What is perspective shortening?
Away/smaller object → smaller visual angle
What is light and shadows?
Light and shadows create perception of depth

Technology is HMD (Head) or RMD (Room) with graphical processing units
What are the algorithms for generation in vision?
Geometrical modeling
What are the algorithms for rendering in vision? [3]
