Member Function Documentation

◆ all_points_at_value()

template<int DC, int DB>

void geometry::d_uniform_point_locator< DC, DB >::all_points_at_value	(	const sec_vd_value_type *	xvalue,
		size_type	xvalue_ub,
		block< chart_point_3d > &	xresult
	)

virtual

Finds all chart points at which coordinates() has value xvalue and appends them to xresult. Note that charts overlap at their boundaries and hence if xvalue lies on a boundary it is contained in more than one chart.

Precondition

xvalue != 0

xvalue_ub >= this->dc()

this->db() <= 3

Issue:: does clipping make sense here? We've already expanded the domain slightly in update_domain(), why do we need to clip as well?

Postcondition

xresult.ct() >= old_xresult_ct

for(int i = ( old_xresult_ct ); i < ( xresult.ct() ); ++ i ) xresult[i].is_valid()

Implements geometry::point_locator.

		block< branch_point_pair > &	xresult
	)

virtual

Finds one chart point in each branch at which coordinates() has value xvalue and appends them to xresult. Note that uniform sections can't really have branches, so this is just a synonym for point_at_value.
