topCircumferenceRadius:
The radius of the circumference at the top of the volcano. You
probably want to make this value significantly greater than zero.
slopeRadius:
The radius of the upward slope of the volcano.
slicesCircumference:
How many slices to chop the quarter circumference of the volcano into.
The total number of triangular surfaces making up this volcano will be
2 * slicesCircumference * slicesSlope .
slicesSlope:
How many slices to chop the vertical slope of the volcano into.
The total number of triangular surfaces making up this volcano will be
2 * slicesCircumference * slicesSlope .
crossSection:
The distance from the top of the volcano to the bottom of the
brushes extending downwards from the volcano.
offsetTopInsteadOfBottom:
Alters the pattern of the mesh by flipping the even-odd 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 volcano, 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 volcano will be pushed back so that
the top of the volcano
is no longer vertical. It "relaxes" the top of the volcano 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 volcano
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 volcano 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
volcano, set this flag whenever the pipe brushes are generated with
adjustForOverlappingPipeCuts also.
adjustForOverlappingBowlCuts:
Use this when joining other structures that have this flag set.
invertSlopeVertices:
The original vertices that make up the slope of the volcano are
flipped after all of the adjust and/or extrude flags are
applied; the vertex at the rim of the volcano becomes the
vertex at the bottom and vice-versa. So, for example,
if we are extruding vertices and using this flag together,
the bottom of the volcano 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 volcano.
