org.web3d.x3d.jsail.fields.X3DConcreteField
org.web3d.x3d.jsail.fields.MFColorRGBAObject
All Implemented Interfaces:
MFColorRGBA, MField, X3DField
public class MFColorRGBAObject
extends X3DConcreteField
implements MFColorRGBA
This utility class provides a concrete implementation corresponding to MFColorRGBA X3D field type.


Note that SFColorObject provides a variety of color constants.

Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). MFColorRGBA specifies zero or more SFColorRGBA 4-tuples, where each color value is an RGBA 4-tuple of floating point numbers in range [0,1]. Alpha (opacity) values = (1 - transparency). The default value of an uninitialized MFColor field is the empty list. Individual SFColorRGBA array values are optionally separated by commas in XML syntax.
