Member Function Documentation

gsSolid< T >::gsSolidHalfFaceHandle addFace

(

std::vector< gsSolidHeVertexHandle >

V

)

add one face as a trimmed surface, the order of the vertices in V must be either CCW or CW when viewing from infinity for all faces

gsSolid< T >::gsSolidHalfFaceHandle addFace	(	std::vector< std::vector< gsSolidHeVertexHandle > >	loopV,
		gsTrimSurface< T > *	tsurf
	)

Add a half face to the solid.

Parameters

loopV	a vector of vectors of vertices of one loop, the first vector is the outer loop
tsurf	a (pointer to) trimmed surface

std::vector< typename gsSolid< T >::gsSolidHalfEdgeHandle > impedingEdges

(

gsSolidHalfEdgeHandle

he

)

const

Check if the solid is separatable along a given edge he by collecting all "impeding edges" which connect the two faces incident to he.

void insertNewVertex

(

gsSolidHalfEdgeHandle

he

)

Insert a new vertex to an edge of the volume.

Parameters

he	the half-edge into which to insert the vertex

Note

This insertion only affects the volume containing the HE.

gsSolid< T >::gsSolidHalfFaceHandle splitFace	(	gsSolidHalfFaceHandle	f,
		gsSolidHeVertexHandle	startVertex,
		gsSolidHeVertexHandle	endVertex,
		gsBSpline< T > *	domainSpline
	)

Split a face f along a given spline. Returns the new face created as a result. The new face will have the edges from startVertex to endVertex and the reverse of domainSpline. The original face f will retain the edges from endVertex to startVertex and gain domainSpline (forwards).
