- * Returns true if the specified GLU core- or extension-function can be
- * successfully used through this GLU instance. By "successfully" we mean
- * that the function is both <i>callable</i> on the machine running the
- * program and <i>available</i> on the current display.<P>
- *
- * A GLU function is <i>callable</i> if it is a GLU core- or extension-function
- * that is supported by the underlying GLU implementation. The function is
- * <i>available</i> if the OpenGL implementation on the display meets the
- * requirements of the GLU function being called (because GLU functions utilize
- * OpenGL functions). <P>
- *
- * Whether or not a GLU function is <i>callable</i> is determined as follows:
- * <ul>
- *   <li>If the function is a GLU core function (i.e., not an
- *   extension), <code>gluGetString(GLU_VERSION)</code> is used to determine the
- *   version number of the underlying GLU implementation on the host.
- *   then the function name is cross-referenced with that specification to
- *   see if it is part of that version's specification.
- *
- *   <li> If the function is a GLU extension, the function name is
- *   cross-referenced with the list returned by
- *   <code>gluGetString(GLU_EXTENSIONS)</code> to see if the function is one of
- *   the extensions that is supported by the underlying GLU implementation.
- * </ul>
- *
- * Whether or not a GLU function is <i>available</i> is determined as follows:
- * <ul>
- *   <li>If the function is a GLU core function then the function is first
- *   cross-referenced with the GLU specifications to find the minimum GLU
- *   version required to <i>call</i> that GLU function. Then the following table
- *   is consulted to determine the minimum GL version required for that version
- *   of GLU:
- *   <ul>
- *   <li> GLU 1.0 requires OpenGL 1.0
- *   <li> GLU 1.1 requires OpenGL 1.0
- *   <li> GLU 1.2 requires OpenGL 1.1
- *   <li> GLU 1.3 requires OpenGL 1.2
- *   </ul>
- *   Finally, <code>glGetString(GL_VERSION)</code> is used to determine the
- *   highest OpenGL version that both host and display support, and from that it
- *   is possible to determine if the GL facilities required by the GLU function
- *   are <i>available</i> on the display.
- *
- *   <li> If the function is a GLU extension, the function name is
- *   cross-referenced with the list returned by
- *   <code>gluGetString(GLU_EXTENSIONS)</code> to see if the function is one of
- *   the extensions that is supported by the underlying GLU implementation.
- * </ul>
- *
- * <b>NOTE:</b>The availability of a function may change at runtime in
- * response to changes in the display environment. For example, when a window
- * is dragged from one display to another on a multi-display system, or when
- * the properties of the display device are modified (e.g., changing the color
- * depth of the display). Any application that is concerned with handling
- * these situations correctly should confirm availability after a display
- * change before calling a questionable OpenGL function. To detect a change in
- * the display device, please see {@link
- * GLEventListener#displayChanged(GLAutoDrawable,boolean,boolean)}.
- *
- * @param gluFunctionName the name of the OpenGL function (e.g., use
- * "gluNurbsCallbackDataEXT" to check if the <code>

- *
- *   To understand how the winding rule works, consider that the input
- *   contours partition the plane into regions.  The winding rule determines
- *   which of these regions are inside the polygon.<P>
- *
- *   For a single contour C, the winding number of a point x is simply the
- *   signed number of revolutions we make around x as we travel once around C
- *   (where CCW is positive).  When there are several contours, the individual
- *   winding numbers are summed.  This procedure associates a signed integer
- *   value with each point x in the plane.  Note that the winding number is
- *   the same for all points in a single region.<P>
- *
- *   The winding rule classifies a region as "inside" if its winding number
- *   belongs to the chosen category (odd, nonzero, positive, negative, or
- *   absolute value of at least two).  The previous GLU tessellator (prior to
- *   GLU 1.2) used the "odd" rule.  The "nonzero" rule is another common way

- *   oriented CW. The <b>GLU_TESS_BEGIN</b> and <b>GLU_TESS_BEGIN_DATA</b>
- *   callbacks use the type GL_LINE_LOOP for each contour.
- * </UL>
- * <BR><b>GLU_TESS_TOLERANCE</b>
- * <UL>
- *   Specifies a tolerance for merging features to reduce the size of the
- *   output. For example, two vertices that are very close to each other
- *   might be replaced by a single vertex.  The tolerance is multiplied by the
- *   largest coordinate magnitude of any input vertex; this specifies the
- *   maximum distance that any feature can move as the result of a single
- *   merge operation.  If a single feature takes part in several merge
- *   operations, the toal distance moved could be larger.<P>
- *
- *   Feature merging is completely optional; the tolerance is only a hint.

- * These callbacks are used by the tessellation object to describe how a

- *
- * <b>GLU_TESS_BEGIN</b>
- * <UL>
- *   The begin callback is invoked like {@link javax.media.opengl.GL#glBegin
- *   glBegin} to indicate the start of a (triangle) primitive. The method
- *   takes a single argument of type int. If the
- *   <b>GLU_TESS_BOUNDARY_ONLY</b> property is set to <b>GL_FALSE</b>, then
- *   the argument is set to either <b>GL_TRIANGLE_FAN</b>,
- *   <b>GL_TRIANGLE_STRIP</b>, or <b>GL_TRIANGLES</b>. If the

- *
- * <PRE>
- *         void begin(int type);</PRE><P>
- *
- * <b>GLU_TESS_BEGIN_DATA</b>
- * <UL>
- *   The same as the <b>GLU_TESS_BEGIN</b> callback except
- *   that it takes an additional reference argument. This reference is
- *   identical to the opaque reference provided when

- *   was called. The method prototype for this callback is:
- * </UL>
- *
- * <PRE>
- *         void beginData(int type, Object polygonData);</PRE>
- *
- * <b>GLU_TESS_EDGE_FLAG</b>
- * <UL>
- *   The edge flag callback is similar to
- *   {@link javax.media.opengl.GL#glEdgeFlag glEdgeFlag}. The method takes
- *   a single boolean boundaryEdge that indicates which edges lie on the
- *   polygon boundary. If the boundaryEdge is <b>GL_TRUE</b>, then each vertex

- *   boundaryEdge is <b>GL_FALSE</b>, then each vertex that follows begins an
- *   edge that lies in the polygon interior. The edge flag callback (if

- *
- *   Since triangle fans and triangle strips do not support edge flags, the
- *   begin callback is not called with <b>GL_TRIANGLE_FAN</b> or
- *   <b>GL_TRIANGLE_STRIP</b> if a non-null edge flag callback is provided.
- *   (If the callback is initialized to null, there is no impact on
- *   performance). Instead, the fans and strips are converted to independent

- *
- * <b>GLU_TESS_EDGE_FLAG_DATA</b>

- *   The same as the <b>GLU_TESS_EDGE_FLAG</b> callback except that it takes
- *   an additional reference argument. This reference is identical to the

- *         void edgeFlagData(boolean boundaryEdge, Object polygonData);</PRE>
- *
- * <b>GLU_TESS_VERTEX</b>
- * <UL>
- *   The vertex callback is invoked between the begin and end callbacks. It is
- *   similar to {@link javax.media.opengl.GL#glVertex3f glVertex3f}, and it
- *   defines the vertices of the triangles created by the tessellation
- *   process. The method takes a reference as its only argument. This

- *         void vertexData(Object vertexData, Object polygonData);</PRE>
- *
- * <b>GLU_TESS_END</b>
- * <UL>
- *   The end callback serves the same purpose as
- *   {@link javax.media.opengl.GL#glEnd glEnd}. It indicates the end of a
- *   primitive and it takes no arguments. The method prototype for this
- *   callback is:
- * </UL>
- *
- * <PRE>
- *         void end();</PRE>
- *
- * <b>GLU_TESS_END_DATA</b>

- *   {@link #gluTessBeginPolygon gluTessBeginPolygon}
- *   was called. The method prototype for this callback is:
- * </UL>
- *
- * <PRE>
- *         void endData(Object polygonData);</PRE>
- *
- * <b>GLU_TESS_COMBINE</b>
- * <UL>
- *   The combine callback is called to create a new vertex when the
- *   tessellation detects an intersection, or wishes to merge features. The
- *   method takes four arguments: an array of three elements each of type
- *   double, an array of four references, an array of four elements each of
- *   type float, and a reference to a reference. The prototype is:
- * </UL>
- *

- *                      float[] weight, Object[] outData);</PRE>
- *
- * <UL>
- *   The vertex is defined as a linear combination of up to four existing
- *   vertices, stored in <i>data</i>. The coefficients of the linear
- *   combination are given by <i>weight</i>; these weights always add up to 1.
- *   All vertex pointers are valid even when some of the weights are 0.
- *   <i>coords</i> gives the location of the new vertex.<P>
- *
- *   The user must allocate another vertex, interpolate parameters using
- *   <i>data</i> and <i>weight</i>, and return the new vertex pointer
- *   in <i>outData</i>. This handle is supplied during rendering callbacks.
- *   The user is responsible for freeing the memory some time after
- *   {@link #gluTessEndPolygon gluTessEndPolygon} is
- *   called.<P>
- *
- *   For example, if the polygon lies in an arbitrary plane in 3-space, and a
- *   color is associated with each vertex, the <b>GLU_TESS_COMBINE</b>
- *   callback might look like this:
- * </UL>
