Projecting Real World Coordinates to Screen Coordinates

Real world doesn't really comes with coordinate grid imposed on it, so we need to impose one. For the sake of convince lets say that our camera is at the origin of the world (0,0,0). The camera projects the world onto a screen.

Real World Coordinates & Screen Pixel Coordinates

• [] two angles (y-z and x-z)

Point of View

• [] Distance of the screen to the camera determines how much real world coordinates are packed into a single screen coordinate (pixels)
