Class GpuLbvhBatch

constructor

• new GpuLbvhBatch(
      device: GPUDevice,
      label: string,
      pipelines: Record<LbvhKernel, GPUComputePipeline>,
      sortPipelines: RadixSortPipelines,
      geometries: readonly GpuMeshGeometry[],
      options: Required<GpuBuildOptions>,
  ): GpuLbvhBatch

  Parameters

  • device: GPUDevice
  • label: string
  • pipelines: Record<LbvhKernel, GPUComputePipeline>
  • sortPipelines: RadixSortPipelines
  • geometries: readonly GpuMeshGeometry[]
  • options: Required<GpuBuildOptions>

  Returns GpuLbvhBatch

ReadonlynodeFormat

ReadonlytriangleLeaves

destroy

• destroy(): void

  Frees the scratch, the inputs and the uniforms. Trees handed out by finish are not touched.

  Returns void

encode

• encode(
      encoder: GPUCommandEncoder,
      timestampWrites?: GPUComputePassTimestampWrites,
      stageTimestamps?: (
          stage:
              | "sort"
              | "triangles"
              | "boxes"
              | "morton"
              | "clear"
              | "climb"
              | "mark"
              | "rank"
              | "emit",
      ) => GPUComputePassTimestampWrites,
  ): void

  Records every mesh's build into encoder: copies of any GPU-buffer inputs, then one compute pass. timestampWrites (optional) times the pass.

  For a breakdown, stageTimestamps instead puts each step in a pass of its own and times it with the writes it returns. The extra passes cost a little time themselves, so use it to compare steps, not to time the build.

  Parameters

  • encoder: GPUCommandEncoder
  • OptionaltimestampWrites: GPUComputePassTimestampWrites
  • OptionalstageTimestamps: (
        stage:
            | "sort"
            | "triangles"
            | "boxes"
            | "morton"
            | "clear"
            | "climb"
            | "mark"
            | "rank"
            | "emit",
    ) => GPUComputePassTimestampWrites

  Returns void

finish

• finish(): Promise<GpuTreeBuffers>

  Reads every mesh's stats back (one copy and one map), checks them, and returns the trees. Call after submitting an encode. Frees the batch's scratch; the trees stay until the caller destroys them.

  Returns Promise<GpuTreeBuffers>
