Element¶
-
class
LRSplines.Element(u_min: float, v_min: float, u_max: float, v_max: float, level: int = 0)[source]¶ -
add_supported_b_spline(b_spline)[source]¶ Adds a B-spline to the list of supported B-splines.
Parameters: b_spline – B-spline to add
-
area¶ Returns the area of the element.
Returns: area of the element
-
contains(u: float, v: float) → bool[source]¶ Returns True if this element contains the point (u, v)
Parameters: - u – u_component
- v – v_component
Returns:
-
evaluate_basis(u, v)[source]¶ Evaluates all the supported B-splines at the point u, v :param u: :param v: :return:
-
fetch_neighbours()[source]¶ Returns a list of neighbouring elements based on supported B-splines.
Returns:
-
get_supported_b_spline(i: int)[source]¶ Returns the i-th supported B-spline.
Parameters: i – index of supported B-spline Returns: b-spline i
-
has_supported_b_spline(b_spline) → bool[source]¶ Returns True if given b_spline is among the list of supported b-splines.
Parameters: b_spline – B-spline to check Returns: True or False
-
intersects(other: LRSplines.element.Element) → bool[source]¶ Returns true if this element intersects the other element with positive area.
Parameters: other – the element to check intersection with. Returns: true or false
-
is_overloaded() → bool[source]¶ Returns true if the number of supported B-splines on this element is greater than (d1 + 1)*(d2 + 1).
Returns: true if overloaded, false otherwise
-
midpoint¶ Returns the midpoint of the element.
Returns: midpoint of the element
-
remove_supported_b_spline(b_spline)[source]¶ Removes a B-spline from the list of supported B-splines.
Parameters: b_spline – B-spline to remove
