public RCHandleAC<class Bod>

CTriSetC

TriSetC()

Constructor.
empty triset

TriSetC(const IntT nvertex,const IntT nelement)

create an empty TriSetC with space allocated to put 'nvertex' verticies and 'nelement' triangles

TriSetC(FilenameC filename)

load file in .tri format (triangles only, index 0..N-1)

TriSetC(SArray1dC<Vector3dC> v,SArray1dC<TriC> e)

Construct from an array of vectors and one of tri's.

TriSetC(const PolopsC & Oth)

Construct from Polops.

TriSetC Copy() const

new physical copy
-------------------------------------------- Load Empty

void PutVertex(const IndexT iIndex,const Vector3dC v)

Put a vertex into structure.

void PutElement(const IndexT iIndex,const TriC t)

Put an element into structure.
--------------------------------------------- Access

IntT NumVertex() const

Access the number of vertices in the TriSet

IntT NumElement() const

Access the number of triangles in the TriSet

Vector3dC & Vertex(const IndexT iIndex)

Access to a particular vertex position

Vector3dC Vertex(const IndexT iIndex) const

Const access to a particular vertex position

const TriC & Element(const IntT iIndex) const

TriC& Element(const IntT index); does not guarantee pointers access i^th element

TriC & Element(const IndexT iIndex)

TriC * PElement(const IndexT iIndex)

pointer to ith element CAUTION - should return ref counter iterator... use in TriSet3to2 --------------------------------------------- Operations

void Save(FilenameC filename)

save to file 'name' in .tri format

void SaveVRML(FilenameC filename)

save vrml 2 format (geometry only)

RealT Length(const IntT i1,const IntT i2)

RealT AverageEdgeLength()

RealT MinimumEdgeLength()

void ConstrainEdgeLength(const RealT maximum_edge_length)

constrain the edge lenght of this triset to 'maximum_edge_length'

void ConstrainNormals(const Vector3dC common_normal)

constrain all element normals to be in orientation as 'common_normal' ie not >90 to common_normal

Vector3dC AverageNormal()

average element normal

Vector3dC VertexNormal(const IndexT iIndex)

return vertex normal (setup an internal array of vertex normals)

Vector3dC SurfaceNormal(RealT dAlpha,RealT dBeta,IndexT iElement)

Return an interpolated surface normal
dAlpha and dBeta are barycentric coordinates of a point on iElement. The returned vector is the interpolated normal at this point.

void Limits(Vector3dC & xmin,Vector3dC & xmax)

bounding volume in 3D

BooleanT IsSetupBound() const

returns setup status of bound

void SetupBound()

Setup boundary information for each TriC Element (call in constructor)

void Transform(RigidTransC & transform)

Rigid transform of all verticies

Vector3dC Centroid()

Centre of triset - average vertex position

void TransformAboutCentroid(RigidTransC & transform)

Rigid transform of all verticies - for rotation about centroid i) triset is translated so that centroid = origin ii) transform is applied iii) inverse of step (i) is applied

PolopsC ExportPolops() const

Export to polops.

ostream & operator<<(ostream & s,const BodyTriSetC & t)

RCAbstractC Abstract()

Create an abstract handle to this object.

BooleanT IsHandleType(const DT &) const
