Member Function Documentation

void GU_Flatten::addActivePinGroup

(

const char *

name

)

Create a vertex group of all pins used during the flattening, both initial and user-specified.

void GU_Flatten::addDistortionAttribute

(

)

Creates a vertex attribute for angular distortion and computes the distortion for all islands. It also creates the input vertex equivalence classes (myInputVertexClasses).

void GU_Flatten::addIslandAttribute

(

bool

add

)

Creates a primitive attribute for island number.

void GU_Flatten::addOriginalPinGroup

(

const char *

name

)

Create a vertex group of all original pins.

void GU_Flatten::addPin	(	int	prim,
		int	vert,
		fpreal	u,
		fpreal	v
	)

Add one pinned point.

void GU_Flatten::addPointIdAttribute

(

)

void GU_Flatten::addSeamsGroup

(

const char *

name

)

bool GU_Flatten::flattenAndPack

(

)

Updates UVs in myTGdp and packs all islands into unit square. Once finished, myTGdp will hold UVs as created after flattening with the initially assigned pins. Returns true if interrupted and false otherwise

int GU_Flatten::getNumIslands ( )

const std::string GU_Flatten::getWarningMessage ( )

inline

Definition at line 114 of file GU_Flatten.h.

int GU_Flatten::reflattenWithPins

(

)

Re-flattens islands affected by changes in current pins. Returns 1 if was interrupted and 0 otherwise

void GU_Flatten::updateExtraSeamsGroup

(

const GA_EdgeGroup *

exgp

)

Change the extra cuts edge group.

void GU_Flatten::updatePrimitiveGroup

(

const GA_PrimitiveGroup *

prims

)

Change the primitive group.
