Class InstancePatch

constructor

• new InstancePatch(
      parent: TransformNode,
      matrixBuffer: Float32Array,
  ): InstancePatch

  Parameters

  • parent: TransformNode
  • matrixBuffer: Float32Array

  Returns InstancePatch

Readonlyinstances

Readonlyparent

clearInstances

• clearInstances(): void

  Clears all instances from the patch. They will be disposed and will not render anymore. The copy of the given base mesh will also be disposed. The matrix buffer will be kept though, which means that calling createInstances() will reuse the same buffer.

  Returns void

createInstances

• createInstances(baseMeshes: { distance: number; mesh: Mesh }[]): void

  Creates instances of a copy of the given base mesh (or transform node in the case of HierarchyInstancePatch). The instances will be positioned according to the matrix buffer given in the constructor.

  Parameters

  • baseMeshes: { distance: number; mesh: Mesh }[]

  Returns void

  Throws

  Error if baseMesh is not a Mesh in the case of InstancePatch and ThinInstancePatch.

dispose

• dispose(): void

  Releases all held resources

  Returns void

getCurrentMesh

• getCurrentMesh(): Mesh

  Returns Mesh

getLodMeshes

• getLodMeshes(): Mesh[]

  Returns Mesh[]

getNbInstances

• getNbInstances(): number

  Returns the number of instances currently rendered.

  Returns number

handleLod

• handleLod(distance: number): void

  Parameters

  • distance: number

  Returns void

isEnabled

• isEnabled(): boolean

  Returns boolean

setEnabled

• setEnabled(enabled: boolean): void

  Parameters

  • enabled: boolean

  Returns void
