The rendering state consists of the following:<p> <ul> <li>Coloring attributes - defines attributes used in color selection and shading. These attributes are defined in a ColoringAttributes object.</li><p> <li>Line attributes - defines attributes used to define lines, including the pattern, width, and whether antialiasing is to be used. These attributes are defined in a LineAttributes object.</li><p> <li>Point attributes - defines attributes used to define points, including the size and whether antialiasing is to be used. These attributes are defined in a PointAttributes object.</li><p> <li>Polygon attributes - defines the attributes used to define polygons, including culling, rasterization mode (filled, lines, or points), constant offset, offset factor, and whether back back facing normals are flipped. These attributes are defined in a PolygonAttributes object.</li><p> <li>Rendering attributes - defines rendering operations, including the alpha test function and test value, the raster operation, whether vertex colors are ignored, whether invisible objects are rendered, and whether the depth buffer is enabled. These attributes are defined in a RenderingAttributes object.</li><p> <li>Transparency attributes - defines the attributes that affect transparency of the object, such as the transparency mode (blended, screen-door), blending function (used in transparency and antialiasing operations), and a blend value that defines the amount of transparency to be applied to this Appearance component object.</li><p> <li>Material - defines the appearance of an object under illumination, such as the ambient color, diffuse color, specular color, emissive color, and shininess. These attributes are defined in a Material object.</li><p> <li>Texture - defines the texture image and filtering parameters used when texture mapping is enabled. These attributes are defined in a Texture object.</li><p> <li>Texture attributes - defines the attributes that apply to texture mapping, such as the texture mode, texture transform, blend color, and perspective correction mode. These attributes are defined in a TextureAttributes object.</li><p> <li>Texture coordinate generation - defines the attributes that apply to texture coordinate generation, such as whether texture coordinate generation is enabled, coordinate format (2D or 3D coordinates), coordinate generation mode (object linear, eye linear, or spherical reflection mapping), and the R, S, and T coordinate plane equations. These attributes are defined in a TexCoordGeneration object.</li><p> <li>Texture unit state - array that defines texture state for each of <i>N</i> separate texture units. This allows multiple textures to be applied to geometry. Each TextureUnitState object contains a Texture object, TextureAttributes, and TexCoordGeneration object for one texture unit. If the length of the texture unit state array is greater than 0, then the array is used for all texture state; the individual Texture, TextureAttributes, and TexCoordGeneration objects in this Appearance object are not used and and must not be set by an application. If the length of the texture unit state array is 0, the multi-texture is disabled and the Texture, TextureAttributes, and TexCoordGeneration objects in the Appearance object are used. If the application sets the existing Texture, TextureAttributes, and TexCoordGeneration objects to non-null values, they effectively define the state for texture unit 0. If the TextureUnitState array is set to a non-null, non-empty array, the individual TextureUnitState objects define the state for texture units 0 through <i>n</i> -1. If both the old and new values are set, an exception is thrown. </li> </ul><P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../javax/media/j3d/ColoringAttributes.html" title="class in javax.media.j3d"><CODE>ColoringAttributes</CODE></A>, <A HREF="../../../javax/media/j3d/LineAttributes.html" title="class in javax.media.j3d"><CODE>LineAttributes</CODE></A>, <A HREF="../../../javax/media/j3d/PointAttributes.html" title="class in javax.media.j3d"><CODE>PointAttributes</CODE></A>, <A HREF="../../../javax/media/j3d/PolygonAttributes.html" title="class in javax.media.j3d"><CODE>PolygonAttributes</CODE></A>, <A HREF="../../../javax/media/j3d/RenderingAttributes.html" title="class in javax.media.j3d"><CODE>RenderingAttributes</CODE></A>, <A HREF="../../../javax/media/j3d/TransparencyAttributes.html" title="class in javax.media.j3d"><CODE>TransparencyAttributes</CODE></A>, <A HREF="../../../javax/media/j3d/Material.html" title="class in javax.media.j3d"><CODE>Material</CODE></A>, <A HREF="../../../javax/media/j3d/Texture.html" title="class in javax.media.j3d"><CODE>Texture</CODE></A>, <A HREF="../../../javax/media/j3d/TextureAttributes.html" title="class in javax.media.j3d"><CODE>TextureAttributes</CODE></A>, <A HREF="../../../javax/media/j3d/TexCoordGeneration.html" title="class in javax.media.j3d"><CODE>TexCoordGeneration</CODE></A>, <A HREF="../../../javax/media/j3d/TextureUnitState.html" title="class in javax.media.j3d"><CODE>TextureUnitState</CODE></A></DL><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_COLORING_ATTRIBUTES_READ">ALLOW_COLORING_ATTRIBUTES_READ</A></B></CODE><BR> Specifies that this Appearance object allows reading its coloringAttributes component information.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_COLORING_ATTRIBUTES_WRITE">ALLOW_COLORING_ATTRIBUTES_WRITE</A></B></CODE><BR> Specifies that this Appearance object allows writing its coloringAttributes component information.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_LINE_ATTRIBUTES_READ">ALLOW_LINE_ATTRIBUTES_READ</A></B></CODE><BR> Specifies that this Appearance object allows reading its line component information.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_LINE_ATTRIBUTES_WRITE">ALLOW_LINE_ATTRIBUTES_WRITE</A></B></CODE><BR> Specifies that this Appearance object allows writing its line component information.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_MATERIAL_READ">ALLOW_MATERIAL_READ</A></B></CODE><BR> Specifies that this Appearance object allows reading its material component information.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_MATERIAL_WRITE">ALLOW_MATERIAL_WRITE</A></B></CODE><BR> Specifies that this Appearance object allows writing its material component information.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_POINT_ATTRIBUTES_READ">ALLOW_POINT_ATTRIBUTES_READ</A></B></CODE><BR> Specifies that this Appearance object allows reading its point component information.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/Appearance.html#ALLOW_POINT_ATTRIBUTES_WRITE">ALLOW_POINT_ATTRIBUTES_WRITE</A></B></CODE><BR> Specifies that this Appearance object allows writing its point component⌨️ 快捷键说明
