meshmaker.inc - various mesh2 objects by splines.
<dl>
<dt><code>MSM(SplineArray, SplRes, Interp_type, InterpRes, FileName)</code>
<dd>Generates a mesh2 from an array of splines and optionally writes the mesh2 object as a file of the given <code>FileName</code>. 
The uv_coordinates come from the square <0,0> - <1,1>. 
The spline is evaluated from t=0 to t=1. 
For the normal calculation, it is required that all splines (also linear_spline) have one extra
point before t=0 and after t=1.

<dt><code>BuildWriteMesh2(VecArr, NormArr, UVArr, U, V, FileName)</code>
<dd>Generates and optionally writes a mesh2 object based on 3 input arrays,
the number of quads in U and V direction and a filename. 
<code>VecArr</code> : The array that contains the vertices of the triangles in the mesh. 
<code>NormArr</code> : The array with the normal vectors that go with the vertices. 
<code>UVArr</code> : The array containing the uv_vectors. 
<code>U</code> : The amount of subdivisions of the surface in the u-direction. 
<code>V</code> : The amount of subdivisions in the v-direction. 
Based on the U and V values the face_indices of the triangles in the mesh are calculated. 
<code>FileName</code> : The name of the file to which the mesh will be written.
If is an empty string (""), no file will be written. 
If the file extension is 'obj' a Wavefront objectfile will be written. 
If the extension is 'pcm' a compressed mesh file is written. 
If a file name is given, the macro will first check if it already exists. 
If that is so, it will try to parse the existing file unless it's a '*.obj', '*.pcm' or '*.arr' file as POV-Ray
can not read them directly. In this case a new mesh will be generated,
but the existing files will _not_ be over-written.

<dt><code>BuildSpline(Arr, SplType)</code>
<dd>A helper macro for MSM() 
Generates from a array <code>Arr</code> a spline of the given spline type <code>SplType</code>.

<dt><code>CheckFileName(FileName)</code>
<dd>A helper macro for MSM() 
If Return has a value of 0 the mesh will not be build,
but it will be parsed from file.

<dt><code>LInterpolate(Val, Min, Max)</code>
<dd>A helper macro for MSM() 
Linear interpolation of a vector or float between <code>Min</code> and <code>Max</code>. 
<code>Min</code> : minimal float value or vector. 
<code>Max</code> : Maximal float value or vector. 
<code>Val</code> : A float in the range 0 - 1.

<dt><code>RangeMM() = function(Val,Rmin,Rmax,Min,Max)</code>
<dd>A helper function for MSM() 
Adjusts input values in the range [<code>RMin, RMax</code>] to fit in the range [Min, Max].
<code>Val</code>: A float value in the range [Rmin, Rmax].

<dt><code>Parametric(__F1__, __F2__, __F3__, UVmin, UVmax, Iter_U, Iter_V, FileName)</code>
<dd>Generates a mesh2 object from the parametric uv functions <code>__F1__, __F2__, __F3__</code>
in the ranges between <code>UVmin</code> and <code>UVmax</code> with the iteration steps

<code>Iter_U</code> and <code>Iter_V</code> and optionally saves the mesh2 object as a file with the name <code>FileName</code>.

<dt><code>Paramcalc(UVmin, UVmax, Iter_U, Iter_V, FileName)</code>
<dd>The kernel of the macro Parametric(). See <code>Parametric()</code>.

<dt><code> Prism1(Spl, ResSpl, PSpl, PRes, FileName)</code>
<dd>Generates a mesh2 object by extruding the spline <code>Spl</code> along the y-axis with the resolution spline <code>ResSpl</code>.
In every step the spline is scaled by the 'relative' distance from the
y-axis of the second spline (PSpl). 
The uv_coordinates come from the square <0,0> - <1,1>. 
<code>Spl</code> : The spline to be extruded. 
The spline is evaluated from t=0 to t=1. For the normal calculation, 
it is required that all splines (also linear_spline) have one extra 
point before t=0 and after t=1.
<code>ResSpl</code> : The amount of triangles to be used along the spline.
<code>PSpl</code> : The spline that determines by what amount the extrusion 
is scaled in each step. The scaling is based on the relative distance from the y-axis. 
That is, at t=0 the scale is always 1, so that the start of the shape is 
identical to the spline <code>Spl</code>. 
PSpl also sets the height of the resulting shape (its y-value at t=1). 
The spline is evaluated from t=0 to t=1. For the normal calculation, 
it is required that all splines (also linear_spline) have one extra 
point before t=0 and after t=1. 
<code>FileName</code> : The name of the file to which the mesh will be written. 
If is an empty string (""), no file will be written. If a file name is given, the macro 
will first check if it already exists. If that is so, it will expect a 
mesh2 with the name "Surface" and try to parse the existing file. 

<dt><code>Lathe(Spl, ResSpl, Rot, ResRot, FileName)</code>
<dd>This macro generates a mesh2 object by rotating a two-dimensional curve about the y-axis. 
The uv_coordinates come from the square <0,0> - <1,1>. 
<code>Spl : The spline to be rotated.
The spline is evaluated from t=0 to t=1. For the normal calculation,
it is required that all splines (also linear_spline) have one extra
point before t=0 and after t=1.
<code>ResSpl</code> : The amount of triangles to be used along the spline.
<code>Rot</code> : The angle the spline has to be rotated. 
<code>ResRot</code> : The amount of triangles to be used in the circumference. 
<code>FileName</code> : The name of the file to which the mesh will be written. 
If is an empty string (""), no file will be written. 
If the file extension is 'obj' a Wavefront objectfile will be written. 
If the extension is 'pcm' a compressed mesh file is written. 
If a file name is given, the macro will first check if it already exists. 
If that is so, it will try to parse the existing file unless it's a '*.obj', 
'*.pcm' or '*.arr' file as POV-Ray can not read them directly. In this case a new 
mesh will be generated, but the existing files will _not_ be over-written. 

<dt><code>Coons(Spl1, Spl2, Spl3, Spl4, Iter_U, Iter_V, FileName)</code>
<dd>Generates a mesh2 'coons surface' defined by four splines, all attached head to tail to the previous / next one. 
The uv_coordinates come from the square <0,0> - <1,1>. 
<code>Spl1 - 4</code> : The four spline that define the surface. 
The splines are evaluated from t=0 to t=1. 
<code>Iter_U</code> : The resolution for the splines 1 and 3. 
<code>Iter_V</code> : The resolution for the splines 2 and 4. 
<code>FileName</code> : The name of the file to which the mesh will be written. 
If is an empty string (""), no file will be written. 
If the file extension is 'obj' a Wavefront objectfile will be written. 
If the extension is 'pcm' a compressed mesh file is written. 
If a file name is given, the macro will first check if it already exists. 
If that is so, it will try to parse the existing file unless it's a '*.obj', 
'*.pcm' or '*.arr' file as POV-Ray can not read them directly. In this case a new 
mesh will be generated, but the existing files will _not_ be over-written.

<dt><code>TwoVarSurf(__Fuv, Urange, Vrange, Iter_U, Iter_V, FileName)</code>
<dd>Generates a mesh2 object by extruding an uv-function.
<code>Urange</code> : The range in x direction. 
<code>Vrange</code> : The range in y direction. 
<code>Iter_U</code> : The resolution in x direction. 
<code>Iter_V</code> : The resolution in y direction. 
<code>FileName</code> : The name of the file to which the mesh will be written. 
If is an empty string (""), no file will be written. If a file name is given, the macro 
will first check if it already exists. If that is so, it will expect a 
mesh2 with the name "Surface" and try to parse the existing file.

<dt><code>SweepSpline1(Track,Shape,Waist,U,V,Filename)</code>
<dd>Generates a mesh2 object by extruding a spline <code>Shape</code> along <code>Track</code>
and optionally writes it as a file with method 1. 
<code>FileName</code> : The name of the file to which the mesh will be written.
If is an empty string (""), no file will be written. If a file name is given, the macro 
will first check if it already exists. If that is so, it will expect a 
mesh2 with the name "Surface" and try to parse the existing file.
<dt><code>SweepSpline2(Track,Shape,Waist,U,V,Filename)</code>
<dd>Generates a mesh2 object by extruding a spline <code>Shape</code> along <code>Track</code>
and optionally writes it as a file with method 2. 
<code>FileName</code> : The name of the file to which the mesh will be written.
If is an empty string (""), no file will be written. If a file name is given, the macro 
will first check if it already exists. If that is so, it will expect a 
mesh2 with the name "Surface" and try to parse the existing file.
