Function documentation

TGLFaceSet(const TBuffer3D& buffer)

 constructor

void SetFromMesh(const RootCsg::TBaseMesh* m)

 Should only be done on an empty faceset object

void EnforceTriangles()

 Use GLU tesselator to replace all polygons with N > 3 with triangles.
 After this call polygon descriptions are changed.
 New vertices are not expected -- exception is thrown if this is
 requested by the triangulator. Support for adding of new vertices can be
 provided.

void DirectDraw(TGLRnrCtx& rnrCtx) const

 Debug tracing

Int_t CheckPoints(const Int_t* source, Int_t* dest) const

 CheckPoints

Bool_t Eq(const Double_t* p1, const Double_t* p2)

 test equality

void CalculateNormals()

 CalculateNormals

Bool_t GetEnforceTriangles()

 Get current state of static flag EnforceTriangles.

void SetEnforceTriangles(Bool_t e)

 Set state of static flag EnforceTriangles.
 When this is set, all tesselations will be automatically converted into
 triangle-only meshes.
 This is needed to export TGeo shapes and CSG meshes to external
 triangle-mesh libraries that can not handle arbitrary polygons.

std::vector<Double_t>& GetVertices()

{ return fVertices; }

std::vector<Double_t>& GetNormals()

{ return fNormals; }

std::vector<Int_t>& GetPolyDesc()

{ return fPolyDesc; }

UInt_t GetNbPols()

{ return fNbPols; }

void GLDrawPolys() const
