static

void GU_SubDivPatch::catclark

(

UT_Array< GU_SubDivPatch * > &

patches

)

Catmull-clark subdivision

Perform subdivision on this patch, creating a new set of subpatches. The caller attains ownership of the patches.

void GU_SubDivPatch::catclarkPatches ( GU_SubDivPatch *  face = 0 )

protected

Creates subpatches within this patch. If a face is supplied, we'll only construct subpatches on the boundary with the face.

void GU_SubDivPatch::clearFlag ( uint8  f )

inline

Definition at line 361 of file GU_SubDivPatch.h.

GU_SubDivPatch* GU_SubDivPatch::copy

(

)

const

Make an independent copy of this patch with new vertices and edges.

void GU_SubDivPatch::decRefCount

(

)

void GU_SubDivPatch::decRefCountInternal ( )

void GU_SubDivPatch::dumpGeo

(

)

const

Dump geometry for the patch as a draw file.

static void GU_SubDivPatch::freePatch ( GU_SubDivPatch *  patch )

static

bool GU_SubDivPatch::getBezier	(	UT_Array< GU_SubDivVertex * > &	vtx,
		UT_Array< float * > &	vtxdata
	)		const

If we're a bezier, returns the bezier hull. The correct vertex attribute associations are returned in the vtxdata array. If we're not a bezier, false is returned.

GU_SubDivVertex* GU_SubDivPatch::getChild ( )

inline

Return the face centroid.

Return the next vertex after vtx.

int GU_SubDivPatch::getValence ( ) const

Return the number of edges and vertices bordering this patch.

inline

Definition at line 341 of file GU_SubDivPatch.h.

void GU_SubDivPatch::getVertices

(

UT_Array< GU_SubDivVertex * > &

vtx

)

const

Get internal and external vertices bordering this patch.

bool GU_SubDivPatch::isLive ( ) const

inline

Definition at line 351 of file GU_SubDivPatch.h.

void GU_SubDivPatch::makeLive

(

)

Live patches are allowed to be externally referenced and keep additional references to the surrounding ring of patches so that all the data required for subdivision is available.

void GU_SubDivPatch::reverse

(

)

Reverse the vertex order for this patch. We'll keep a flag to determine whether it is flipped relative to the original geometry.
