/**
* The TexCoordGeneration object contains all parameters needed for
* automatic texture coordinate generation. It is included as part
* of an Appearance component object.
* <p>
* Texture coordinates determine which texel in the texture map is
* assigned to a given vertex. Texture coordinates are interpolated
* between vertices, similarly to how colors are interpolated between
* two vertices of lines and polygons.
* <p>
* Texture coordinates consist of two, three or four coordinates.
* These coordinates
* are referred to as the <i>S</i>, <i>T</i>, <i>R</i>, and <i>Q</i>
* coordinates.
* 2D textures use the <i>S</i> and <i>T</i> coordinates. 3D textures
* use the <i>S</i>, <i>T</i> and <i>R</i> coordinates. The <i>Q</i>
* coordinate, similar to the <i>w</i> coordinate of the <i>(x, y, z, w)</i>
* object coordinates, is used to create homogeneous coordinates.
* <p>
* Rather than the programmer having to explicitly assign texture
* coordinates, Java 3D can automatically generate the texture
* coordinates to achieve texture mapping onto contours.
* The TexCoordGeneration attributes specify the functions for automatically
* generating texture coordinates. The texture attributes that can be
* defined are:
* <p><ul>
* <li>Texture format - defines whether the generated texture
* coordinates are 2D, 3D, or 4D:<p>
* <ul>
* <li>TEXTURE_COORDINATE_2 - generates 2D texture coordinates
* (S and T).<p>
* <li>TEXTURE_COORDINATE_3 - generates 3D texture coordinates
* (S, T, and R).<p>
* <li>TEXTURE_COORDINATE_4 - generates 4D texture coordinates
* (S, T, R, and Q).<p>
* </ul>
* <li>Texture generation mode - defines how the texture coordinates
* are generated:<p>
* <ul>
* <li>OBJECT_LINEAR - texture coordinates are generated as a linear
* function in object coordinates. The function used is:<p>
* <ul>
* <code>g = p<sub>1</sub>x<sub>o</sub> + p<sub>2</sub>y<sub>o</sub> + p<sub>3</sub>z<sub>o</sub> + p<sub>4</sub>w<sub>o</sub></code>
* <p>
* where<br>
* <ul><code>g</code> is the value computed for the coordinate.<br>
* <code>p<sub>1</sub></code>, <code>p<sub>2</sub></code>,
* <code>p<sub>3</sub></code>, and <code>p<sub>4</sub></code>
* are the plane equation coefficients (described below).<br>
* x<sub>o</sub>, y<sub>o</sub>, z<sub>o</sub>, and w<sub>o</sub> are
* the object coordinates of the vertex.<p>
* </ul></ul>
* <li>EYE_LINEAR - texture coordinates are generated as a linear
* function in eye coordinates. The function used is:<p>
* <ul>
* <code>g = p<sub>1</sub>'x<sub>e</sub> + p<sub>2</sub>'y<sub>e</sub> + p<sub>3</sub>'z<sub>e</sub> + p<sub>4</sub>'w<sub>e</sub></code>
* <p>
* where<br>
* <ul><code>x<sub>e</sub></code>, <code>y<sub>e</sub></code>,
* <code>z<sub>e</sub></code>, and w<sub>e</sub></code> are the eye
* coordinates of the vertex.<br>
* <code>p<sub>1</sub>'</code>, <code>p<sub>2</sub>'</code>,
* <code>p<sub>3</sub>'</code>, and <code>p<sub>4</sub>'</code>
* are the plane equation coefficients transformed into eye
* coordinates.<p>
* </ul></ul>
*
* <li>SPHERE_MAP - texture coordinates are generated using
* spherical reflection mapping in eye coordinates. Used to simulate
* the reflected image of a spherical environment onto a polygon.<p>
*
* <li>NORMAL_MAP - texture coordinates are generated to match
* vertices' normals in eye coordinates. This is only available if
* TextureCubeMap is available.
* </li><p>
*
* <li>REFLECTION_MAP - texture coordinates are generated to match
* vertices' reflection vectors in eye coordinates. This is only available
* if TextureCubeMap is available.
* </li><p>
* </ul>
* <li>Plane equation coefficients - defines the coefficients for the
* plane equations used to generate the coordinates in the
* OBJECT_LINEAR and EYE_LINEAR texture generation modes.
* The coefficients define a reference plane in either object coordinates
* or in eye coordinates, depending on the texture generation mode.
* <p>
* The equation coefficients are set by the <code>setPlaneS</code>,
* <code>setPlaneT</code>, <code>setPlaneR</code>, and <code>setPlaneQ</code>
* methods for each of the S, T, R, and Q coordinate functions, respectively.
* By default the equation coefficients are set as follows:<p>
* <ul>
* plane S = (1.0, 0.0, 0.0, 0.0)<br>
* plane T = (0.0, 1.0, 0.0, 0.0)<br>
* plane R = (0.0, 0.0, 0.0, 0.0)<br>
* plane Q = (0.0, 0.0, 0.0, 0.0)<p>
* </ul></ul>
* Texture coordinate generation is enabled or disabled by the
* <code>setEnable</code> method. When enabled, the specified
* texture coordinate is computed according to the generating function
* associated with the coordinate. When disabled, subsequent vertices
* take the specified texture coordinate from the current set of
* texture coordinates.<p>
