Background • Attributes

Description

The backdrop is a light and dark gray checkered pattern using a single image specified for all URL attributes. There are six spheres positioned at the "center" of each of the patterns.

VRIGNETTE Notes

Background can make simple and complex backdrops depending on what image or texture is specified. If you omit the images, and use only sky and ground attributes, the backdrop will filled with those colors.

Example

Rotate the vrignette to view the geometry.
