onProcessCpu()

onProcessCpu: ({ framework, frameStartResult, processGpuResult })

Description

onProcessCpu() is called to read results of GPU processing and return usable data. Called with { frameStartResult, processGpuResult }. Data returned by modules in onProcessGpu will be present as processGpu.modulename where the name is given by module.name = "modulename".

Parameter	Description
framework	The framework bindings for this module for dispatching events.
frameStartResult	The data that was provided at the beginning of a frame.
processGpuResult	Data returned by all installed modules during onProcessGpu.

Returns

Any data that you wish to provide to onUpdate should be returned. It will be provided to that method as processCpuResult.modulename

Example

XR8.addCameraPipelineModule({
  name: 'mycamerapipelinemodule',
  onProcessCpu: ({ frameStartResult, processGpuResult }) => {
    const GLctx = frameStartResult.GLctx
    const { cameraTexture } = frameStartResult
    const { camerapixelarray, mycamerapipelinemodule } = processGpuResult

    // Do something interesting with mycamerapipelinemodule.gpuDataA and mycamerapipelinemodule.gpuDataB
    ...

    // These fields will be provided to onUpdate
    return {cpuDataA, cpuDataB}
  },
