* gluTessProperty is used to control properites stored in a
* tessellation object. These properties affect the way that the polygons are
* interpreted and rendered. The legal value for which are as
* follows:* * GLU_TESS_WINDING_RULE *
* * 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.
* * 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.
* * 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 * to define the interior. The other three rules are useful for polygon CSG * operations. *
* * Feature merging is completely optional; the tolerance is only a hint. * The implementation is free to merge in some cases and not in others, or * to never merge features at all. The initial tolerance is 0.
* * The current implementation merges vertices only if they are exactly * coincident, regardless of the current tolerance. A vertex is spliced * into an edge only if the implementation is unable to distinguish which * side of the edge the vertex lies on. Two edges are merged only when both * endpoints are identical. *
* * If the supplied normal is (0.0, 0.0, 0.0)(the initial value), the normal * is determined as follows. The direction of the normal, up to its sign, is * found by fitting a plane to the vertices, without regard to how the * vertices are connected. It is expected that the input data lies * approximately in the plane; otherwise, projection perpendicular to one of * the three coordinate axes may substantially change the geometry. The sign * of the normal is chosen so that the sum of the signed areas of all input * contours is nonnegative (where a CCW contour has positive area).

* * These callbacks are used by the tessellation object to describe how a * polygon specified by the user is broken into triangles. Note that there are * two versions of each callback: one with user-specified polygon data and one * without. If both versions of a particular callback are specified, then the * callback with user-specified polygon data will be used.

* * GLU_TESS_BEGIN *
* void begin(int type);
* * GLU_TESS_BEGIN_DATA *
* void beginData(int type, Object polygonData);* * GLU_TESS_EDGE_FLAG *
* * 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: *
* void edgeFlag(boolean boundaryEdge);* * GLU_TESS_EDGE_FLAG_DATA *
* void edgeFlagData(boolean boundaryEdge, Object polygonData);* * GLU_TESS_VERTEX *
* void vertex(Object vertexData);* * GLU_TESS_VERTEX_DATA *

* * 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: *
