Properties

meshId

meshId: string

ID of the SceneMesh the triangle belongs to.

objectId

objectId: string

ID of the SceneObject the triangle belongs to.

tHit

tHit: number

Parametric distance along the input ray, in dir-multiples. The hit point equals origin + dir * tHit (modulo the same floating-point round-off as any other ray test).

triangleIndex

triangleIndex: number

Index of the hit triangle (offset into geometry.indices divided by 3).

worldPos

worldPos: Vec3Float

World-space hit point.
