Polygon primitives include triangles, triangle strips, triangle fans, and quads. The polygon attributes that can be defined are:</li> <p><ul> <li>Rasterization mode - defines how the polygon is drawn: as points, outlines, or filled.<p> <ul> <li>POLYGON_POINT - the polygon is rendered as points drawn at the vertices.</li><p> <li>POLYGON_LINE - the polygon is rendered as lines drawn between consecutive vertices.</li><p> <li>POLYGON_FILL - the polygon is rendered by filling the interior between the vertices. The default mode.</li> <p></ul> <li>Face culling - defines which polygons are culled (discarded) before they are converted to screen coordinates.<p> <ul> <li>CULL_NONE - disables face culling.</li> <li>CULL_BACK - culls all back-facing polygons. The default.</li> <li>CULL_FRONT - culls all front-facing polygons.</li> <p></ul> <li>Back-face normal flip - specifies whether vertex normals of back-facing polygons are flipped (negated) prior to lighting. The setting is either true, meaning to flip back-facing normals, or false. The default is false.</li> <p> <li>Offset - the depth values of all pixels generated by polygon rasterization can be offset by a value that is computed for that polygon. Two values are used to specify the offset:</li><p> <ul> <li>Offset bias - the constant polygon offset that is added to the final device coordinate Z value of polygon primitives.</li> <p> <li>Offset factor - the factor to be multiplied by the slope of the polygon and then added to the final, device coordinate Z value of the polygon primitives.</li><p> </ul> These values can be either positive or negative. The default for both of these values is 0.0.<p> </ul><P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../javax/media/j3d/Appearance.html" title="class in
