Fit() [1/3]

static ON_Brep* CRhinoFitPatch::Fit ( ON_SimpleArray< const ON_Geometry * > &  input_geometry, const ON_Surface *  pSrf, double  tolerance  )

static

Input geometry for all Fit functions can consist of any combination of ON_Curves, ON_BrepTrims, ON_Points, ON_PointClouds or ON_Meshes Curves and trims are sampled to get points Trims are sampled for points and normals Simple version of fit Uses a specified starting surface Sample points from the input are pulled to the starting surface to get uv locations on the surface to try to fit to the point locations.

This version of fit exposes all of the controls that the rhino patch command uses. input_geometry: Combination of ON_Curves, ON_BrepTrims, ON_Points, ON_PointClouds or ON_Meshes pSrf: Starting surface or NULL to use a plane fit through the input points u_spans, v_spans: Number of surface spans used when a plane is fit through points to start bTrim: If true, try to find an outer loop from among the input curves and trim the result to that loop bTangency: If true, try to find brep trims in the outer loop of curves and try to fit to the normal direction of the trim's surface at those locations. point_spacing: Basic distance between points sampled from input curves. flexibility: Determines the behavior of the surface in areas where its not otherwise controlled by the input. Lower numbers make the surface behave more like a stiff material, higher, more like a stiff material That is, each span is made to more closely match the spans adjacent to it if there is no input geometry mapping to that area of the surface when the flexibility value is low. The scale is logrithmic. Numbers around 0.001 or 0.1 make the patch pretty stiff and numbers around 10 or 100 make the surface flexible. surface_pull: Tends to keep the result surface where it was before the fit in areas where there is on influence from the input geometry fix_edges[]: Flags to keep the edges of a starting (untrimmed) surface in place while fitting the interior of the surface. Order of flags is left, bottom, right, top tolerance: Tolerance used by input analysis functions for loop finding, trimming, etc.

Fit() [3/3]

static ON_Brep* CRhinoFitPatch::Fit ( ON_SimpleArray< const ON_Geometry * > &  input_geometry, int  u_spans, int  v_spans, double  tolerance  )

static

Simple version of fit Uses a plane with u x v spans Makes a plane by fitting to the points from the input geometry to use as the starting surface. The surface has the specified u and v span count.
