RGBA color nodes are only used to specify multiple colours with alpha for a single geometric shape, such as colours for the faces or vertices of an IndexedFaceSet. A Material node is used to specify the overall material parameters of lit geometry. If both a Material node and a ColorRGBA node are specified for a geometric shape, the colours shall replace the diffuse and transparency components of the material.

RGB or RGBA textures take precedence over colours; specifying both an RGB or RGBA texture and a Color node for geometric shape will result in the Color node being ignored. Details on lighting equations can be found in the Lighting model section of the X3D specification.

ColorRGBA

Specification Link: ColorRGBA

ColorRGBA : X3DColorNode { 
  MFColorRGBA [in,out] color    [NULL] [0,1]
  SFNode      [in,out] metadata NULL   [X3DMetadataObject]
}

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 is no check that the values of the color field are acceptable.

Schema 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

  • The Schema attempts to check that the values of the color field are within the range [0,1]. It does this successfully for values in decimal format but can fail for values in exponent format.

Schematron validation

TBD
