Examples of javax.media.j3d.TransparencyAttributes

javax.media.j3d.TransparencyAttributes
The TransparencyAttributes object defines all attributes affecting transparency of the object. The transparency attributes are:
- Transparency mode - defines how transparency is applied to this Appearance component object:
- Transparency value - the amount of transparency to be applied to this Appearance component object. The transparency values are in the range [0.0, 1.0], with 0.0 being fully opaque and 1.0 being fully transparent.
- Blend function - used in blended transparency and antialiasing operations. The source function specifies the factor that is multiplied by the source color. This value is added to the product of the destination factor and the destination color. The default source blend function is BLEND_SRC_ALPHA. The source blend function is one of the following:
