A background node that uses six static images to compose the backdrop. The common fields of the Background node are described in 24.2 Concepts section of the X3D Specification. For the backUrl, bottomUrl, frontUrl, leftUrl, rightUrl, topUrl fields, browsers shall support the JPEG and PNG image file formats, and in addition, may support any other image format (EXAMPLE  CGM) that can be rendered into a 2D image. Support for the GIF format is recommended (including transparency).

DTD Validation

Children

Children must appear as follows:

  1. A single, optional IS.
  2. A single, optional node derived from X3DMetadataObject for the metadata field.

Attributes

  • There are no limits on the acceptable range of values for the groundAngle field.
  • There is no check that the groundAngle values are nondecreasing.
  • There are no limits on the acceptable range of values for the groundColor field.
  • There is no check that the number of groundColor values is one more than the number of groundAngle values.
  • There are no limits on the acceptable range of values for the skyAngle field.
  • There is no check that the skyAngle values are nondecreasing.
  • There are no limits on the acceptable range of values for the skyColor field.
  • There is no check that the number of skyColor values is one more than the number of skyAngle values.
  • There are no limits on the acceptable range of values for the transparency field.
