Detailed Description

This class holds a polyized geometry for which people can query. This is an alternative representation. This caches the point positions in the SIM_Geometry's space, so are independent of SIM_Geometry's transform.

Member Function Documentation

UT_Vector3 SIM_TriangulatedGeometry::getBaryCenter

(

int

primNum

)

const

Returns the barycenter of the triangle. It is estimated from point density (if any)

virtual bool SIM_TriangulatedGeometry::getIsAlternateRepresentationSubclass

(

)

const [protected, virtual]

Overrides to properly implement this class as a SIM_Data. This object is meant to be updated from the object's geometry at each frame, so we only implement skeleton save, and load methods.

Reimplemented from SIM_Data.

virtual int64 SIM_TriangulatedGeometry::getMemorySizeSubclass

(

)

const [protected, virtual]

Override this function to return an accurate representation of the amount of memory used by this piece of data. The size of subdata should not be included in this calculation.

Reimplemented from SIM_Data.

int SIM_TriangulatedGeometry::getPointCount

(

)

const

Returns the total number of points.

float SIM_TriangulatedGeometry::getPointDensity	(	int	primId,
		int	vtNum
	)			const

Gets the point density, given primitive ID and vertex number.

float SIM_TriangulatedGeometry::getPointDensity

(

int

ptId

)

const

Returns the baryCenter of a given primitive Gets the point density, given point ID

int SIM_TriangulatedGeometry::getPointId	(	int	primId,
		int	vtNum
	)			const

Gets the corresponding point id given a vertex number and a primitive id

UT_Vector4 SIM_TriangulatedGeometry::getPointPos	(	int	primId,
		int	vtNum
	)			const

Gets the position of a point in SIM_Geometry space, given primitive ID and vertex number

UT_Vector4 SIM_TriangulatedGeometry::getPointPos

(

int

ptId

)

const

Gets the position of a point in SIM_Geometry space, given point ID.

int SIM_TriangulatedGeometry::getPrimitiveCount

(

)

const

Gets the number of primitives.

int SIM_TriangulatedGeometry::getVertexCount

(

int

primNum = 0

)

const

Gets the number of vertices of a given primitive.

void SIM_TriangulatedGeometry::init

(

)

const

initializes alternate geometry for lite functions

virtual void SIM_TriangulatedGeometry::initAlternateRepresentationSubclass

(

const SIM_Data &

)

[protected, virtual]

Override this function if getIsAlternateRepresentationSubclass() is overridden to return true. This function is used to initialize the alternate representation based on the data to which it was just attached.

Reimplemented from SIM_Data.
