/** * 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 callable on the machine running the * program and available on the current display. * * A GLU function is callable if it is a GLU core- or extension-function * that is supported by the underlying GLU implementation. The function is * available if the OpenGL implementation on the display meets the * requirements of the GLU function being called (because GLU functions utilize * OpenGL functions). * * Whether or not a GLU function is callable 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 available 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 call 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 available 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> * * NOTE: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.

The legal callbacks are as follows: * * GLU_TESS_BEGIN * <UL> * The begin callback is invoked like {@link javax.media.opengl.GL#glBegin * glBegin} to indicate the start of a (triangle) primitive.

This reference is * identical to the opaque reference provided when * {@link #gluTessBeginPolygon gluTessBeginPolygon} * was called. The method prototype for this callback is: * </UL> * * <PRE> * void beginData(int type, Object polygonData);</PRE> * * GLU_TESS_EDGE_FLAG * <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 GL_TRUE, then each vertex * that follows begins an edge that lies on the polygon boundary, that is, * an edge that separates an interior region from an exterior one. If the * boundaryEdge is GL_FALSE, then each vertex that follows begins an * edge that lies in the polygon interior. The edge flag callback (if * defined) is invoked before the first vertex callback. * * Since triangle fans and triangle strips do not support edge flags, the * begin callback is not called with GL_TRIANGLE_FAN or * GL_TRIANGLE_STRIP 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 * triangles. The method prototype for this callback is: * </UL> * * <PRE> * void edgeFlag(boolean boundaryEdge);</PRE> * * GLU_TESS_EDGE_FLAG_DATA * <UL> * The same as the GLU_TESS_EDGE_FLAG callback except that it takes * an additional reference argument. This reference is identical to the * opaque reference provided when * {@link #gluTessBeginPolygon gluTessBeginPolygon} * was called. The method prototype for this callback is: * </UL> * * <PRE> * void edgeFlagData(boolean boundaryEdge, Object polygonData);</PRE> * * GLU_TESS_VERTEX * <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 prototype for this callback is: * </UL> * * <PRE> * void vertexData(Object vertexData, Object polygonData);</PRE> * * GLU_TESS_END * <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> * * GLU_TESS_END_DATA * <UL> * The same as the GLU_TESS_END callback except that it takes an * additional reference argument.

The method prototype for this callback is: * </UL> * * <PRE> * void endData(Object polygonData);</PRE> * * GLU_TESS_COMBINE * <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> * * <PRE> * void combine(double[] coords, Object[] data, * float[] weight, Object[] outData);</PRE> * * <UL> * The vertex is defined as a linear combination of up to four existing * vertices, stored in data. The coefficients of the linear * combination are given by weight; these weights always add up to 1. * All vertex pointers are valid even when some of the weights are 0. * coords gives the location of the new vertex. * * The user must allocate another vertex, interpolate parameters using * data and weight, and return the new vertex pointer * in outData. This handle is supplied during rendering callbacks. * The user is responsible for freeing the memory some time after * {@link #gluTessEndPolygon gluTessEndPolygon} is * called. * * For example, if the polygon lies in an arbitrary plane in 3-space, and a * color is associated with each vertex, the GLU_TESS_COMBINE * callback might look like this: * </UL> * <PRE> * void myCombine(double[] coords, Object[] data, * float[] weight, Object[] outData) * { * MyVertex newVertex = new MyVertex(); * * newVertex.x = coords[0]; * newVertex.y = coords[1]; * newVertex.z = coords[2]; * newVertex.r = weight[0]*data[0].r + * weight[1]*data[1].r + * weight[2]*data[2].r + * weight[3]*data[3].r; * newVertex.g = weight[0]*data[0].g + * weight[1]*data[1].g + * weight[2]*data[2].g + * weight[3]*data[3].g; * newVertex.b = weight[0]*data[0].b + * weight[1]*data[1].b + * weight[2]*data[2].b + * weight[3]*data[3].b; * newVertex.a = weight[0]*data[0].a + * weight[1]*data[1].a + * weight[2]*data[2].a + * weight[3]*data[3].a; * outData = newVertex; * }</PRE> * * <UL> * If the tessellation detects an intersection, then the * GLU_TESS_COMBINE or GLU_TESS_COMBINE_DATA callback (see * below) must be defined, and it must write a non-null reference into * outData.

This reference is identical to the opaque * reference provided when * {@link #gluTessBeginPolygon gluTessBeginPolygon} * was called. The method prototype for this callback is: * </UL> * * <PRE> * void combineData(double[] coords, Object[] data, float[] weight, Object[] outData, Object polygonData);</PRE> * * GLU_TESS_ERROR * <UL> * The error callback is called when an error is encountered. The one * argument is of type int; it indicates the specific error that occurred * and will be set to one of GLU_TESS_MISSING_BEGIN_POLYGON, * GLU_TESS_MISSING_END_POLYGON, * GLU_TESS_MISSING_BEGIN_CONTOUR, * GLU_TESS_MISSING_END_CONTOUR, GLU_TESS_COORD_TOO_LARGE, * GLU_TESS_NEED_COMBINE_CALLBACK or GLU_OUT_OF_MEMORY. * Character strings describing these errors can be retrieved with the * {@link #gluErrorString gluErrorString} call. The * method prototype for this callback is: * </UL> * * <PRE> * void error(int errnum);</PRE> * * <UL> * The GLU library will recover from the first four errors by inserting the * missing call(s). GLU_TESS_COORD_TOO_LARGE indicates that some * vertex coordinate exceeded the predefined constant * GLU_TESS_MAX_COORD in absolute value, and that the value has been * clamped. (Coordinate values must be small enough so that two can be * multiplied together without overflow.) * GLU_TESS_NEED_COMBINE_CALLBACK indicates that the tessellation * detected an intersection between two edges in the input data, and the * GLU_TESS_COMBINE or GLU_TESS_COMBINE_DATA callback was not * provided.
