BVHParams

Parameters for configuring the BVH (Bounding Volume Hierarchy).

Properties

accurateCulling?

optional accurateCulling: boolean

Enables accurate frustum culling by checking intersections without applying margin to the bounding box.

Default

true

getBBoxFromBSphere?

optional getBBoxFromBSphere: boolean

Defined in: core/InstancedMeshBVH.ts:28

Uses the geometry bounding sphere to compute instance bounding boxes. Otherwise it’s calculated by applying the object’s matrix to all 8 bounding box points. This is faster but less precise. Useful for moving objects. Only works if the geometry’s bounding sphere is centered at the origin.

Default

false

margin?

optional margin: number

Defined in: core/InstancedMeshBVH.ts:20

Margin applied to accommodate animated or moving objects. Improves BVH update performance but slows down frustum culling and raycasting. For static objects, set to 0 to optimize culling and raycasting efficiency.
