Struct PolytopeShape 

pub struct PolytopeShape { /* private fields */ }

PLYT — a convex hull, version 3+. Domino’s dmPolytope.

The chunk stores fixed-size headers and variable-size payloads in two blocks; both halves are folded into this one struct, and the header’s counts are recomputed from the vectors on write. The header’s four pointer fields are filled in by the client at load time and are zero in every file, so they are not kept.

Implementations

impl PolytopeShape

pub fn new() -> Self

Panics

Panics if the native allocation fails.

pub fn vertices(&self) -> &[Vector3f]

Hull corners. Zero-copy view of the underlying std::vector.

pub fn vertices_mut(&mut self) -> &mut [Vector3f]

Zero-copy mutable view. Resize first — the borrow forbids it after.

pub fn set_vertices(&mut self, values: &[Vector3f])

pub fn resize_vertices(&mut self, count: usize)

pub fn face_planes(&self) -> &[Vector4f]

Outward plane of each face, xyz normal and w offset. Zero-copy view of the underlying std::vector.

pub fn face_planes_mut(&mut self) -> &mut [Vector4f]

Zero-copy mutable view. Resize first — the borrow forbids it after.

pub fn set_face_planes(&mut self, values: &[Vector4f])

pub fn resize_face_planes(&mut self, count: usize)

pub fn face_first_edges(&self) -> &[u8]

One entry per face: any half-edge bounding it, as the entry point for walking the face through PolytopeHalfEdge::nextEdge. Zero-copy view of the underlying std::vector.

pub fn face_first_edges_mut(&mut self) -> &mut [u8]

Zero-copy mutable view. Resize first — the borrow forbids it after.

pub fn set_face_first_edges(&mut self, values: &[u8])

pub fn resize_face_first_edges(&mut self, count: usize)

pub fn edges_len(&self) -> usize

pub fn edges(&self, index: usize) -> Option<Ref<'_, PolytopeHalfEdge>>

Borrows element index in place. None when out of range.

pub fn edges_mut( &mut self, index: usize, ) -> Option<RefMut<'_, PolytopeHalfEdge>>

pub fn edges_iter( &self, ) -> impl ExactSizeIterator<Item = Ref<'_, PolytopeHalfEdge>>

Iterate the elements, borrowing each in turn.

pub fn resize_edges(&mut self, count: usize)

pub fn centroid(&self) -> Vector3f

Volume-weighted, not the vertex average.

pub fn set_centroid(&mut self, value: Vector3f)

pub fn volume(&self) -> f32

Hull volume.

pub fn set_volume(&mut self, value: f32)

pub fn surface_area(&self) -> f32

Hull surface area.

pub fn set_surface_area(&mut self, value: f32)

pub fn padding_04(&self) -> u32

The four-byte gaps each count leaves in front of its 64-bit pointer, and the one that trails the header. Uninitialised in the files — some carry fragments of unrelated strings — so they are kept verbatim for writing.

pub fn set_padding_04(&mut self, value: u32)

pub fn padding_14(&self) -> u32

pub fn set_padding_14(&mut self, value: u32)

pub fn padding_2c(&self) -> u32

pub fn set_padding_2c(&mut self, value: u32)

pub fn padding_4c(&self) -> u32

pub fn set_padding_4c(&mut self, value: u32)

Trait Implementations

impl Debug for PolytopeShape

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PolytopeShape

fn default() -> Self

Returns the “default value” for a type.

impl Drop for PolytopeShape

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
