%%
%%  The standard GLU error codes are `?GLU_INVALID_ENUM',  `?GLU_INVALID_VALUE',

%% @doc Return a string describing the GLU version or GLU extensions 
%%
%% ``glu:getString'' returns a pointer to a static string describing the  GLU version or
%% the GLU extensions that are supported. 
%%
%%  The version number is one of the following forms:  
%%
%% `major_number.minor_number'`major_number.minor_number.release_number'.  
%%
%%  The version string is of the following form:  
%%
%% `version number&lt;space&gt;vendor-specific information'
%%
%%  Vendor-specific information is optional. Its format and contents depend on the implementation.
%% 
%%
%%  The standard GLU contains a basic set of features and capabilities. If a company or group
%% of companies wish to support other features, these may be included as extensions to the
%% GLU.  If  `Name'  is  `?GLU_EXTENSIONS', then ``glu:getString'' returns a space-separated

%% @doc Define a viewing transformation
%%
%% ``glu:lookAt'' creates a viewing matrix derived from an eye point, a reference point
%% indicating the center of the scene, and an `UP' vector.  
%%
%%  The matrix maps the reference point to the negative `z' axis and the eye point to
%% the origin. When a typical projection matrix is used, the center of the scene therefore
%% maps to the center of the viewport. Similarly, the direction described by the `UP'
%% vector projected onto the viewing plane is mapped to the positive `y'  axis so that
%% it points upward in the viewport. The `UP' vector must not be parallel to the line
%% of sight from the eye point to the reference point. 
%%
%%  Let  
%%
%%  F=(centerX-eyeX centerY-eyeY centerZ-eyeZ)
%%
%%  Let `UP' be the vector  (upX upY upZ).  
%%
%%  Then normalize as follows:   f=F/(||F||)
%%
%%  UP"=UP/(||UP||)
%%
%%  Finally, let   s=f×UP", and   u=s×f. 
%%
%%  M is then constructed as follows:  M=(s[0] s[1] s[2] 0 u[0] u[1] u[2] 0-f[0]-f[1]-f[2] 0 0 0 0 1)
%%
%%  and ``glu:lookAt'' is equivalent to   glMultMatrixf(M); glTranslated(-eyex, -eyey,

%% @doc Draw an arc of a disk
%%
%% ``glu:partialDisk'' renders a partial disk on the   z=0 plane. A partial disk is  similar
%% to a full disk, except that only the subset of the disk from  `Start'  through  `Start' 
%%  +  `Sweep'  is included (where 0 degrees is along the  +f2yf axis, 90 degrees along
%% the +`x' axis, 180 degrees along the -`y' axis, and  270 degrees along the -`x'
%%  axis). 
%%
%%  The partial disk has a radius of   `Outer'  and contains a concentric circular hole
%% with a radius  of  `Inner' . If  `Inner'  is 0, then no hole is generated. The partial
%% disk is subdivided around the `z' axis into slices (like pizza slices) and also about
%% the `z' axis into rings  (as specified by  `Slices'  and  `Loops' , respectively).
%% 
%%
%%  With respect to orientation, the +`z'  side of the partial disk is considered to
%%  be outside (see  {@link glu:quadricOrientation/2} ). This means that if the  orientation
%% is set to `?GLU_OUTSIDE', then any normals generated  point along the +`z' axis.
%% Otherwise, they point along the -`z'  axis. 
%%
%%  If texturing is turned on (with  {@link glu:quadricTexture/2} ), texture coordinates are
%% generated linearly such that where   r=outer, the value at (`r', 0, 0) is  (1.0,

%% @doc Set up a perspective projection matrix
%%
%% ``glu:perspective'' specifies a viewing frustum into the world coordinate system. In
%% general, the aspect ratio in ``glu:perspective'' should match the aspect ratio of the

%% as wide in `x' as it is in `y'. If the viewport is twice as wide as it is tall,
%% it displays the image without distortion. 
%%
%%  The matrix generated by ``glu:perspective'' is multipled by the current matrix, just
%% as if  {@link gl:multMatrixd/1}  were called with the generated matrix. To load the perspective
%% matrix onto the current matrix stack instead, precede the call to ``glu:perspective''

%% @doc Define a picking region
%%
%% ``glu:pickMatrix'' creates a projection matrix that can be used to restrict drawing
%% to a small region of the viewport. This is typically useful to determine what objects
%% are being drawn near the cursor. Use ``glu:pickMatrix'' to restrict drawing to a small
%% region around the cursor. Then, enter selection mode (with  {@link gl:renderMode/1} ) and
%% rerender the scene. All primitives that would have been drawn near the cursor are identified
%% and stored in the selection buffer. 
%%
%%  The matrix created by ``glu:pickMatrix'' is multiplied by the current matrix just as
%% if  {@link gl:multMatrixd/1}  is called with the generated matrix. To effectively use the
%% generated pick matrix for picking, first call  {@link gl:loadIdentity/0}  to load an identity
%% matrix onto the perspective matrix stack. Then call ``glu:pickMatrix'', and, finally,
%% call a command (such as  {@link glu:perspective/4} ) to multiply the perspective matrix by
%% the pick matrix. 
%%
%%  When using ``glu:pickMatrix'' to pick NURBS, be careful to turn off the NURBS  property
%% `?GLU_AUTO_LOAD_MATRIX'. If `?GLU_AUTO_LOAD_MATRIX' is not turned off, then
%% any NURBS surface rendered is subdivided differently with the pick matrix than the way
%% it was subdivided without the pick matrix.
