Struct LocalManifold 

pub struct LocalManifold {
    pub normal: Vec3,
    pub triangle_normal: Vec3,
    pub points: [LocalManifoldPoint; 32],
    pub point_count: i32,
    pub triangle_index: i32,
    pub i1: i32,
    pub i2: i32,

    pub feature: TriangleFeature,
    pub triangle_flags: i32,
}

A local manifold with no dynamic information. Used by collide functions.

Unlike C (which holds a b3LocalManifoldPoint* into an external buffer), this embeds a fixed MAX_POINTS_PER_TRIANGLE point array so mesh narrow-phase can gather up to 32 clip points before cluster reduction. Convex callers still pass capacity == MAX_MANIFOLD_POINTS. (b3LocalManifold)

Fields

normal: Vec3

Local normal in frame A.

triangle_normal: Vec3

The triangle normal.

points: [LocalManifoldPoint; 32]

The manifold points.

point_count: i32

The number of manifold points. Only bounded by the buffer capacity.

triangle_index: i32

The index of the triangle.

i1: i32

Vertex 1 index.

i2: i32

Vertex 2 index.

i3: i32

Vertex 3 index.

squared_distance: f32

The squared distance of a sphere from a triangle. For ghost collision reduction.

feature: TriangleFeature

The triangle feature involved.

triangle_flags: i32

b3MeshEdgeFlags.
