cylinder(Quad::i(),
Base :: f(),
Top :: f(),
Height :: f(),
Slices :: i(),
Stacks :: i()) ->

glu:cylinder/6 draws a cylinder oriented along the z axis. The base of the cylinder is placed at z
= 0 and the top at z=height. Like a sphere, a cylinder is subdivided around the z axis into slices
and along the z axis into stacks.

memory it uses. Once glu:deleteQuadric/1 has been called, Quad cannot be used again.

disk(Quad::i(),
Inner :: f(),
Outer :: f(),
Slices :: i(),
Loops :: i()) ->
ok
glu:disk/5 renders a disk on the z = 0 plane. The 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
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).
External documentation.
errorString(Error::enum())->string()glu:errorString/1 produces an error string from a GL or GLU error code. The string is in ISO Latin
1 format. For example, glu:errorString/1(?GLU_OUT_OF_MEMORY) returns the string outofmemory.

getString(Name::enum())->string()glu:getString/1 returns a pointer to a static string describing the GLU version or the GLU
extensions that are supported.

ok
Types:
EyeX = EyeY = EyeZ = CenterX = CenterY = CenterZ = UpX = UpY = UpZ = f()
glu:lookAt/9 creates a viewing matrix derived from an eye point, a reference point indicating the
center of the scene, and an UP vector.
External documentation.
newQuadric()->i()glu:newQuadric/0 creates and returns a pointer to a new quadrics object. This object must be
referred to when calling quadrics rendering and control functions. A return value of 0 means that
there is not enough memory to allocate the object.
External documentation.
ortho2D(Left::f(),Right::f(),Bottom::f(),Top::f())->
ok
glu:ortho2D/4 sets up a two-dimensional orthographic viewing region. This is equivalent to calling
gl:ortho/6 with near=-1 and far=1.

partialDisk(Quad,Inner,Outer,Slices,Loops,Start,Sweep)->ok
Types:
Quad = i()
Inner = Outer = f()
Slices = Loops = i()
Start = Sweep = f()
glu:partialDisk/7 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).
External documentation.
perspective(Fovy::f(),Aspect::f(),ZNear::f(),ZFar::f())->
ok
glu:perspective/4 specifies a viewing frustum into the world coordinate system. In general, the
aspect ratio in glu:perspective/4 should match the aspect ratio of the associated viewport. For
example, aspect=2.0 means the viewer's angle of view is twice 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.

pickMatrix(X::f(),
Y :: f(),
DelX :: f(),
DelY :: f(),
Viewport :: {i(), i(), i(), i()}) ->
ok
glu:pickMatrix/5 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/5 to restrict drawing to a small region around the cursor. Then,
enter selection mode (with 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.

{i(), WinX :: f(), WinY :: f(), WinZ :: f()}
Types:
ObjX = ObjY = ObjZ = f()
Model = Proj = matrix()
View = {i(), i(), i(), i()}
glu:project/6 transforms the specified object coordinates into window coordinates using Model,
Proj, and View. The result is stored in WinX, WinY, and WinZ. A return value of ?GLU_TRUE
indicates success, a return value of ?GLU_FALSE indicates failure.

Quad. The Orientation values are as follows:
External documentation.
quadricTexture(Quad::i(),Texture::0|1)->okglu:quadricTexture/2 specifies if texture coordinates should be generated for quadrics rendered
with Quad. If the value of Texture is ?GLU_TRUE, then texture coordinates are generated, and if
Texture is ?GLU_FALSE, they are not. The initial value is ?GLU_FALSE.

sphere(Quad::i(),Radius::f(),Slices::i(),Stacks::i())->

glu:sphere/4 draws a sphere of the given radius centered around the origin. The sphere is

longitude and latitude).

VertexPos = binary()
Triangulates a polygon, the polygon is specified by a Normal and Vs a list of vertex positions.
The function returns a list of indices of the vertices and a binary (64bit native float)
containing an array of vertex positions, it starts with the vertices in Vs and may contain newly
created vertices in the end.
