Struct plane_split::BspSplitter

pub struct BspSplitter<A: Copy> { /* private fields */ }

Binary Space Partitioning splitter, uses a BSP tree.

Implementations

impl<A: Copy> BspSplitter<A>

pub fn new() -> Self

Create a new BSP splitter.

impl<A> BspSplitter<A>where
    A: Copy + Debug + Default,

pub fn reset(&mut self)

Put the splitter back in it initial state.

Call this at the beginning of every frame when reusing the splitter.

pub fn add(&mut self, poly: Polygon<A>)

Add a polygon to the plane splitter.

This is where most of the expensive computation happens.

pub fn sort(&mut self, view: Vector3D<f64>) -> &[Polygon<A>]

Sort the added and split polygons against the view vector.

Call this towards the end of the frame after having added all polygons.

pub fn solve(
    &mut self,
    input: &[Polygon<A>],
    view: Vector3D<f64>
) -> &[Polygon<A>]where
    A: Copy,

Process a set of polygons at once.

pub fn order(&self, node: NodeIdx, base: &Polygon<A>, out: &mut Vec<Polygon<A>>)

Build the draw order of this sub-tree into an out vector, so that the contained planes are sorted back to front according to the view vector defined as the base plane front direction.
