OCC.IntPolyh module¶

This package provides algorithms to computestarting points for the surface surfaceintersection packages. Those starting points areused if the two surfaces are bi-parametricsurfaces (bezier, nurbs, algorithm surfaces …)This package provides methodsto compute meshes on the two surfaces. The meshes canbe refined if necessary. It is the major improvementto the Intf package which gives the same kind ofressources.to intersect the two meshesto give approximated starting-points. Those points areorganised in lines, when the points belong to a samesection line, or returned as isolated points when theycan neither define a new line nor be linked to anexistant line.A starting-point contains 3d information, parametricionformation and quality criterion. (i.e. X,Y,Z, U1,V1,U2,V2, Incidence). Incidence is a real wich gives anestimated angle between the two surfaces near theintersection point.
