Class ExtendedTriangle

three-mesh-bvh's ExtendedTriangle, engine-free: a triangle with cached separating axes, plane and degeneracy. Set needsUpdate after moving a corner (the queries update it then).

Implements

Constructors

constructor

new ExtendedTriangle(
    a?: BvhVector3Like,
    b?: BvhVector3Like,
    c?: BvhVector3Like,
): ExtendedTriangle
Parameters
- Optionala: BvhVector3Like
- Optionalb: BvhVector3Like
- Optionalc: BvhVector3Like
Returns ExtendedTriangle
- Defined in query/shapes.ts:1186

Properties

`Readonly`degenerateSegment

degenerateSegment: BvhSegment = ...

isDegenerateIntoPoint

isDegenerateIntoPoint: boolean = false

isDegenerateIntoSegment

isDegenerateIntoSegment: boolean = false

`Readonly`isExtendedTriangle

isExtendedTriangle: true = ...

needsUpdate

needsUpdate: boolean = true

Set after moving a, b or c; the queries then call updateExtendedTriangle first.

`Readonly`plane

plane: BvhPlane = ...

`Readonly`points

points: readonly BvhVector3[]

[a, b, c].

`Readonly`satAxes

satAxes: readonly BvhVector3[] = ...

The face normal, then the edges a - b, b - c, c - a.

`Readonly`satBounds

satBounds: readonly SeparatingAxisBounds[] = ...

The corners' interval along each of satAxes.
