Struct ControlPointGrid 

pub struct ControlPointGrid { /* private fields */ }

The control point grid, [u][v].

A distinct type rather than a bare Vec<Vec<EntityId>> so the u/v convention is stated once and the rectangularity check cannot be skipped.

Implementations

impl ControlPointGrid

pub fn u_count(&self) -> usize

Number of control points along u; the outer list length.

pub fn v_count(&self) -> usize

Number of control points along v; the inner list length.

pub fn get(&self, u_index: usize, v_index: usize) -> Option<EntityId>

The control point at (u_index, v_index).

pub fn rows(&self) -> &[Vec<EntityId>]

The rows, each a constant-u run of control points.
