示例1: end
void end( const TWallVertexVector& vb, TIntVector& polygon, TIntVector& ib )
{
assert( polygonCount );
if( polygonCount == 1 ) {
// trivial case, just output input polygon
polygon.resize( 0 );
polygon.reserve( vertices.size() );
int idx0 = *vertices.begin();
int idx = idx0;
do {
polygon.push_back( idx );
const TIntVector& vnext = vertexNexts[idx];
assert( vnext.size() == 1 );
idx = vnext[0];
} while( idx != idx0 );
triangulator::process( vb, polygon, ib );
} else {
// mark vertex types
markVertexTypes();
// trace and triangulate the polygon(s)
traceBorder( vb, polygon, ib );
}
}示例2: if
void markVertexTypes()
{
TIntSet::const_iterator vit, vitEnd = vertices.end();
// first pass: mark all interior and single-border vertices
for( vit = vertices.begin(); vit != vitEnd; ++vit ) {
int idx = *vit;
if( vertexUseCount[idx] == 1 ) {
vertexTypes[idx] = VTYPE_SINGLE;
borderVertices.insert( idx );
} else if( isVertexInterior(idx) )
vertexTypes[idx] = VTYPE_INTERIOR;
}
// now, the unmarked vertices are all shared and on border
for( vit = vertices.begin(); vit != vitEnd; ++vit ) {
int idx = *vit;
if( vertexTypes[idx] == VTYPE_NONE ) {
vertexTypes[idx] = VTYPE_MULTI;
borderVertices.insert( idx );
}
}
}示例3:
int getBorderIndex()
{
if( borderVertices.empty() )
return -1;
return *borderVertices.begin();
}
