Class ColoringAttributes


public class ColoringAttributes extends NodeComponent
The ColoringAttributes object defines attributes used in color selection and shading model.

Color

The setColor methods set the current intrinsic red, green, and blue color values of this ColoringAttributes component object. This color is only used for unlit geometry. If lighting is enabled, the material colors are used in the lighting equation to produce the final color. When vertex colors are present in unlit geometry, those vertex colors are used in place of this ColoringAttributes color, unless the vertex colors are ignored.

There are two variations on the setColor methods, one that takes a Color3f and one that takes three floats. No alpha value is allowed (it's automatically set to 1.0). The float values range between 0.0 and 1.0, with 1.0 being full intensity of the color. A color value of (1.0, 1.0, 1.0) is white.

Shading Model

The setShadeModel method sets the shade model for this ColoringAttributes component object. The shade model may be one of the following:

  • FASTEST - use the fastest available method for shading. This shading mode maps to whatever shading model the Java 3D implementor defines as the "fastest," which may be hardware-dependent.
  • NICEST - use the nicest (highest quality) available method for shading. This shading mode maps to whatever shading model the Java 3D implementor defines as the "nicest," shading model, which may be hardware-dependent.
  • SHADE_FLAT - use the flat shading model. This shading model does not interpolate color across the primitive. The primitive is drawn with a single color and the color of one vertex of the primitive is duplicated across all the vertices of the primitive.
  • SHADE_GOURAUD - use the Gouraud (smooth) shading model. This shading model smoothly interpolates the color at each vertex across the primitive. The primitive is drawn with many different colors and the color at each vertex is treated individually. For lines, the colors along the line segment are interpolated between the vertex colors. This is the default shade model if no other is specified.

  • Method Details

    • setColor

      public void setColor(javax.vecmath.Color3f color)
      Sets the intrinsic color of this ColoringAttributes component object. This color is only used for unlit geometry; if lighting is enabled, then the material colors are used in the lighting equation to produce the final color. When vertex colors are present in unlit geometry, those vertex colors are used in place of this ColoringAttributes color unless the vertex colors are ignored.
      Parameters:
      color - the color that is used when lighting is disabled or when material is null
      Throws:
      CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph
      See Also:
    • setColor

      public void setColor(float r, float g, float b)
      Sets the intrinsic color of this ColoringAttributes component object. This color is only used for unlit geometry; if lighting is enabled, then the material colors are used in the lighting equation to produce the final color. When vertex colors are present in unlit geometry, those vertex colors are used in place of this ColoringAttributes color unless the vertex colors are ignored.
      Parameters:
      r - the red component of the color
      g - the green component of the color
      b - the blue component of the color
