circumferenceRadius: 

The radius of the circumference of the bowl (circumference is the
rim of the bowl). This value should be greater than or equal to
slopeRadius.

slopeRadius: 

The radius of the upward slope of the bowl. Setting
slopeRadius to be equal to circumferenceRadius
will produce a perfectly spherical bowl surface. slopeRadius
should not be greater than circumferenceRadius.

slicesCircumference: 

How many slices to chop the quarter circumference of the bowl into.
The total number of triangular surfaces making up this bowl will be
2 * slicesCircumference * slicesSlope.

slicesSlope: 

How many slices to chop the vertical slope of the bowl into.
The total number of triangular surfaces making up this bowl will be
2 * slicesCircumference * slicesSlope.

crossSection: 

The width and height of the square cross section of the rim of the bowl.
This value should be greater than slopeRadius.

offsetTopInsteadOfBottom: 

Alters the pattern of the mesh by flipping the evenodd rule in which vertices get
rotated by half a slice along the circumference. This is useful
when joining other offset objects to the circumference of the bowl, such as offset
cylinders or funnels.

extrudeTopNSlices: 

If this is greater than zero and if extrudeRadiusFactor is greater than one,
the topmost extrudeTopNSlices vertices of the bowl will be pushed back so that
the top of the bowl
is no longer vertical. It "relaxes" the top of the bowl to have a less steep slope.

extrudeRadiusFactor: 

Used together with extrudeTopNSlices. This value should be greater than one
and extrudeTopNSlices should be greater than zero to make the top of the bowl
less steep. It is possible to use values slightly less than one here to generate an
"oversteep" top, but if used improperly, poor results will be generated, or [possibly]
nothing will be generated at all.
A value of 1.0 corresponds to a normal bowl with perfectly vertical top.
Otherwise, the top vertices are generated based on a radius of
slopeRadius * extrudeRadiusFactor. You can use
this tool for calculating
extrudeRadiusFactor.

adjustForOverlappingPipeCuts: 

In the case where pipe brushes are joined at the seam of this
bowl, set this flag whenever the pipe brushes are generated with
adjustForOverlappingPipeCuts also.

adjustForOverlappingBowlCuts: 

When cutting overlapping bowl brushes at the top (z = 0), set this flag
so that the resulting cut brushes lie on integer coordinates.

invertSlopeVertices: 

The original vertices that make up the slope of the bowl are
flipped after all of the adjust and/or extrude flags are
applied; the vertex at the rim of the bowl becomes the
vertex at the bottom and viceversa. So, for example,
if we are extruding vertices and using this flag together,
the bottom of the bowl will no longer be horizontal.

generateOnlySeam: 

Generates only the seam brushes.

adjustSeamForJoining: 

Perturb the vertices of the seam brushes so that other structures such
as pipes can be joined perfectly to this quarter bowl.
