Struct bismuth::cube::Cursor

pub struct Cursor { /* fields omitted */ }

A contiguous selection of cubes in a tree.

A Cursor is essentially a bounding box with an associated width (granularity) used to isolate cubes in a tree.

Methods

impl Cursor

fn at_point(point: &UPoint3, width: LogWidth) -> Self

fn at_point_with_span(point: &UPoint3, width: LogWidth, span: &UVector3) -> Self

fn from_point_to_point(start: &UPoint3, end: &UPoint3, width: LogWidth) -> Self

fn at_cube<C>(cube: &C) -> Self where
    C: Spatial, 

fn at_cube_with_span<C>(cube: &C, span: &UVector3) -> Self where
    C: Spatial, 

fn from_cube_to_cube<S, E>(start: &S, end: &E) -> Self where
    S: Spatial,
    E: Spatial, 

fn origin(&self) -> &UPoint3

Gets the origin of the Cursor.

fn width(&self) -> LogWidth

Gets the width associated with the Cursor, which is the width of the cubes that it selects.

fn span(&self) -> &UVector3

Gets the span of the Cursor from its origin. This is based on the width of the Cursor, and each component essentially selects a number of cubes in the positive direction along that axis. A span of zero means that only one cube is selected by the Cursor.

fn extent(&self) -> UVector3

Gets the extent of the Cursor from its origin.

fn aabb(&self) -> AABB

Gets the AABB of the Cursor.
