colorRange, fitTolerance, hardCornerDetect, hardCornerMaxLength, imageFile, inputMesh, inputMeshUVSet, maxColorDiff, maxPointsAdded, meshQuality, minSegmentSize, outAlpha, outColor, outColorB, outColorData, outColorG, outColorR, outSegFace, output, pointsOnBoundary, quantize, quantizeLevels, segGroupIds, segmentCount, shaderScript, simplifyBoundary, simplifyThreshold, smoothBoundary, smoothFactor, spatialRadius, surfaceOffset

Long name (short name)	Type	Default	Flags
colorRange (crng)	float	4.5
The range of colors we admit into a feature.
fitTolerance (ft)	float	0.007
Attempts to fit lines to the gathered pixel data. This tolerance value indicates how closely lines much match. This value corresponds to the pixel size. The tolerance is pixelSize * fitTolerance
hardCornerDetect (hcd)	bool	1
Attempts to detect sharp corners in segments before simplification and smoothing. It finds hard corners by walking around a segment boundary and finding a group of points whose slope does not change and length is equal to hardCornerMaxLength/100.0 * MAX(imgWidth,imgHeight).
hardCornerMaxLength (hcml)	float	10.0
Used when hardCornerDetect is enabled.
imageFile (if)	string	NULL
Image file to extract geometry from.
segGroupIds (sgi)	integer	-1
Used to map segments to shaders. We need input component ids to properly assign the shaders.
inputMesh (im)	mesh	NULL
Used to drive the tessellation. Since the objective is to place the converted geometry onto the surface. We need to tessellate the geometry so that when we lift the surface to 3d it will be exactly on it without intersections.
inputMeshUVSet (iuv)	string	NULL
Specifies the UVset to use when an input mesh is specified.
maxColorDiff (mcd)	float	0.125
The maximum color difference between two pixels. This value is used to determine if a new pixel should be added to a segment.
maxPointsAdded (mpa)	integer	0
The mesh generator can insert points to acheive a higher quality tessellation (i.e. a tessellation without skinny triangles). This attribute controls how many points are allowed to be added. This attribute can also be used to control the number of triangles.
meshQuality (mq)	double	0.1
Determines the quality of the mesh produced. Zero is the poorest quality and one represents the highest quality.
minSegmentSize (msz)	float	0.005
The minimum segment size expressed as a percentage of a total image size.
surfaceOffset (so)	float	0.01
If a constraint mesh is defined, then this will offset the wrapped surface by using the surface normals of the constraint mesh.
outColorData (ocd)	compound	n/a
Output attribute for color information.
outColor (oc) float3 Colors from the segmented mesh outColorR (ocr) float 0.0 Output color R component outColorG (ocg) float 0.0 Output color G component outColorB (ocb) float 0.0 Output color B component
outAlpha (oa) float 0.0 Output alpha component
outSegFace (ofm)	intArray	empty
Maps the segments to the faces of the generated mesh. Index i corresponds to segment i in aOutColor.
output (out)	mesh	NULL
Output mesh data.
segmentCount (sc)	integer	0
Output attribute indicates the number of segments found.
pointsOnBoundary (pob)	bool	0
The mesh generating can insert points to acheive a higher quality tessellation. This flag allows the point inserter to add points on segment boundaries.
quantize (qut)	bool	0
Forces a quantization of the image before segmentation. This helps find segments in gradient shaded areas. If this attribute is set to true then quantizeLevels is used to determine the number of levels the image should quantized into.
quantizeLevels (qutl)	unsigned char	10
If 'quantize' is set to true then quantizeLevels attribute is used to determine the number of levels of quantization.
shaderScript (shs)	string	NULL
Script to be called when shader assignment needs to be done.
simplifyBoundary (smpl)	bool	1
Tries to remove points along segment boundary that have similar slope. That is, if the slope of line xy is equivalent to the slope of the line to line xz then y can be removed.
simplifyThreshold (smpt)	double	0
Used when simplifyBoundary is enabled.
smoothBoundary (smbd)	bool	1
Toggles the smoothing of the mesh boundary. Smoothing is done by averaging the points together.
smoothFactor (smf)	float	0.5
If smoothBoundary is toggled then the value in smooth factor is used to determine how much the boundary of each segment is smoothed. A value of 0.5 would half the number of points along a mesh segment.
spatialRadius (spr)	integer	7
The search radius used to detect features in the image.
