LiveGraphics3D Example:
A Flock of Birds

Eleven Birds above an African Lake

This example demonstrates the usage of bitmap backgrounds. In this case the background is defined to be "spherical", i.e. rotations are not limited and the bitmap is rotated with the object. However this imposes several restrictions on the bitmap.

Restrictions on Bitmap Backgrounds

This is the JPEG image used as background. In the case of cylindrical backgrounds the left edge has to fit smoothly to the right edge.

However there is a second restriction for spherical backgrounds: There have to be uniformly colored regions at the top and the bottom of the picture.
