Struct ClashSession 

pub struct ClashSession { /* private fields */ }

A clash session: stores per-element geometry, element AABBs, and caches the per-element triangle BVHs that the narrow phase needs.

Implementations

impl ClashSession

pub fn new() -> Self

pub fn ingest( &mut self, positions: &[f32], pos_ranges: &[u32], indices: &[u32], idx_ranges: &[u32], aabbs: &[f32], )

Ingest N elements from flat arenas.

• positions: concatenated per-element vertex coords (x, y, z, ...).
• pos_ranges: 2 per element = [float_offset, float_len].
• indices: concatenated per-element LOCAL (0-based within that element’s vertices) triangle indices.
• idx_ranges: 2 per element = [idx_offset, idx_len].
• aabbs: 6 per element = [minx, miny, minz, maxx, maxy, maxz].

Vertex/AABB coords are f32-sourced; they are stored and computed in f64.

pub fn run_rule( &self, group_a: &[u32], group_b: &[u32], mode: u8, tolerance: f64, clearance: f64, report_touch: bool, ) -> RuleResult

Run one rule.

group_a / group_b are GLOBAL element indices. An empty group_b requests a self-clash within group_a (pairs with i < j by position in group_a). mode: 0 = hard, 1 = clearance. Records carry GLOBAL element indices.

Trait Implementations

impl Default for ClashSession

fn default() -> Self

Returns the “default value” for a type.
