Detailed Description

structure representing a facet mesh, a representation for triangular polygon data using corresponding arrays of data. Note the several more routines in PublicUtilities.h for managing facet meshes. Be careful about maintaining the polygon equation and edge lists.

Member Function Documentation

void FacetMesh::Append ( const FacetMesh & mesh )

void FacetMesh::BuildEdgeList ( )

builds the list of edges for the mesh if the list is already up to date, nothing is done.

void FacetMesh::CalcBBox ( TBBox3D & bBox ) [inline]

computes the bounding box of the mesh

void FacetMesh::CalcPolygonEqnList ( ) [inline]

calculate the list of plane equations

void FacetMesh::Create ( FacetMesh ** outMesh ) [inline, static]

uint32 FacetMesh::FacetsNbr ( ) const [inline]

TFacetMeshRenderFlags FacetMesh::GetRenderFlags ( ) [inline]

boolean FacetMesh::IsEdgeListInvalid ( ) const [inline]

you must call this routine any time the facets change, the edge generators rely on this to generate the edge lists

boolean FacetMesh::IsPolygonEqnListInvalid ( ) const [inline]

you must call this routine any time the facets change, the plane generators rely on this to generate the polygon equations

void FacetMesh::MarkEdgeListInvalid ( ) [inline]

void FacetMesh::MarkPolygonEqnListInvalid ( ) [inline]

void FacetMesh::ReorderFacetsByUVSpaceID ( uint32 uvSpaceCount )

void FacetMesh::SetFacetsCount ( const uint32 numFacets ) [inline]

void FacetMesh::SetRenderFlags ( TFacetMeshRenderFlags renderFlags ) [inline]

void FacetMesh::SetVerticesCount ( const uint32 numVertices ) [inline]

Member Data Documentation

TEdgeList FacetMesh::fEdgeList

TMCArray<Triangle> FacetMesh::fFacets

facets containing 3 indexes to the points in fVertices

TMCArray<TVector3> FacetMesh::fNormals

normals at the vertices

TMCArray<TMCColorRGBA8> FacetMesh::fPolygonBackColors

TMCArray<TMCColorRGBA8> FacetMesh::fPolygonColors

TMCArray<TVector4> FacetMesh::fPolygonEqns

these are the plane equations for the polygons (a combo of unit normal and plane coeff) we use the plane eqn of the form for compute the plane coeff A x + B y + C z + D = 0
