EnvBall uses an image or series of images of a highly reflective
chrome ball in an environment (real world or computer-generated) to
re-create that environment. This is possible because the reflections
in the chrome ball provide a nearly 360 degree view of the environment.
To create an image of a chrome ball, first place a highly reflective chrome ball (sphere) in the
environment (real world or computer generated) that you want to re-create. Place the ball at the
exact location (in the original environment) where you want your model to appear (in the
re-created environment), and take note of the ball's distance from any floor/walls/ceiling or
Photograph (or render) the ball using a telephoto lens, and take note of the camera's elevation
(the angle between the camera's view and the environment's ground plane), and the camera's
inclination (the angle between the camera's view and the environment's YZ plane).
The photo essentially contains a compressed sample of the entire environment, except for the
area directly behind the ball. The highest resolution is in the direction of the camera, so the
image provides the best data compression for that point of view.
