Struct CsgLeaves 

pub struct CsgLeaves {
    pub leaves: Vec<GeomLeaf>,
    pub expr: CsgExpr,
    pub paths: Vec<LeafPath>,
}

Flattened analytic model of one tree: primitive leaves + boolean structure.

Fields

leaves: Vec<GeomLeaf>

expr: CsgExpr

paths: Vec<LeafPath>

Branch-path of each leaf (parallel to leaves), relative to the walk root passed to CsgLeaves::from_dynamic.

Implementations

impl CsgLeaves

pub fn from_dynamic( obj: &DynamicObject, world: DAffine3, aabb_hint: Option<&dyn Fn(&DynamicObject) -> Option<(DVec3, DVec3)>>, ) -> CsgLeaves

Flatten obj into leaves + boolean structure. world is the transform above the walk root; aabb_hint supplies proxy bounds for unsupported subtrees (see AabbHint).

pub fn from_dynamic_unfeatured( obj: &DynamicObject, world: DAffine3, aabb_hint: Option<&dyn Fn(&DynamicObject) -> Option<(DVec3, DVec3)>>, ) -> CsgLeaves

Like Self::from_dynamic, but edge-feature masks are omitted: the solid is the tree as if no chamfer/fillet were applied, with leaf paths keeping the same shape (a feature’s child region stays [0]). Feature lowering resolves its edges against this view so a sibling feature’s cut cannot trim a stored edge short — masks then span the full edge and overlap at shared corners instead of leaving a sliver of the original sharp edge standing (mixed chamfer/fillet corners).

pub fn is_empty(&self) -> bool

The empty solid.

pub fn spans(&self, ro: DVec3, rd: DVec3) -> Vec<HitSpan>

All solid stretches of the ray through the final solid, sorted by t. rd need not be normalized — t stays in ro + t·rd units.

pub fn first_hit(&self, ro: DVec3, rd: DVec3, t_min: f64) -> Option<HitBoundary>

First surface crossing with t > t_min (typically 0.0).

pub fn contains(&self, p: DVec3) -> bool

Whether the final solid contains p (closed: boundary counts as inside).

pub fn boundary_normal( &self, boundary: &HitBoundary, ro: DVec3, rd: DVec3, ) -> DVec3

Outward normal of the final solid at a boundary returned by Self::spans/Self::first_hit (unit length, world space).
