SFColorRGBA
,X3DField
This utility class provides a concrete implementation corresponding to SFColorRGBA X3D field type.
Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the
Note that SFColor 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). SFColorRGBA specifies one RGBA (red-green-blue-alpha) color 4-tuple, 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 SFColorRGBA field is (0 0 0 0). Warning: comma characters within singleton values do not pass strict XML validation.
