示例1: sqrt
int mitk::PointSetDataInteractor::GetPointIndexByPosition(Point3D position, unsigned int time, float accuracy)
{
// iterate over point set and check if it contains a point close enough to the pointer to be selected
PointSet* points = dynamic_cast<PointSet*>(GetDataNode()->GetData());
int index = -1;
if (points == NULL)
{
return index;
}
if (points->GetPointSet(time) == nullptr)
return -1;
PointSet::PointsContainer* pointsContainer = points->GetPointSet(time)->GetPoints();
float minDistance = m_SelectionAccuracy;
if (accuracy != -1 )
minDistance = accuracy;
for (PointSet::PointsIterator it = pointsContainer->Begin(); it != pointsContainer->End(); it++)
{
float distance = sqrt(position.SquaredEuclideanDistanceTo(points->GetPoint(it->Index(), time)));
if (distance < minDistance) // if several points fall within the margin, choose the one with minimal distance to position
{
index = it->Index();
}
}
return index;
