<A NAME="setIgnoreVertexColors(boolean)"><!-- --></A><H3>
setIgnoreVertexColors</H3>
<PRE>
public void <B>setIgnoreVertexColors</B>(boolean&nbsp;ignoreVertexColors)</PRE>
<DL>
<DD>Sets a flag that indicates whether vertex colors are ignored
 for this RenderingAttributes object.  If
 <code>ignoreVertexColors</code> is false, per-vertex
 colors are used, when present in the associated Geometry
 objects, taking precedence over the ColoringAttributes color
 and the specified Material color(s).  If <code>ignoreVertexColors</code>
 is true, per-vertex colors are ignored.  In this case, if
 lighting is enabled, the Material diffuse color will be
 used as the object color.  If lighting is disabled, the
 ColoringAttributes color will be used.  The default value is false.

 the ignoring of per-vertex colors

<A NAME="setRasterOpEnable(boolean)"><!-- --></A><H3>
setRasterOpEnable</H3>
<PRE>
public void <B>setRasterOpEnable</B>(boolean&nbsp;rasterOpEnable)</PRE>
<DL>
<DD>Sets the rasterOp enable flag for this RenderingAttributes
 component object.  When set to true, this enables logical
 raster operations as specified by the setRasterOp method.
 Enabling raster operations effectively disables alpha blending,
 which is used for transparency and antialiasing.  Raster
 operations, especially XOR mode, are primarily useful when
 rendering to the front buffer in immediate mode.  Most
 applications will not wish to enable this mode.
