calculateCastAnchor

• calculateCastAnchor(thumbKnuckle, middleKnuckle): vec3

• Calculates anchor for the raycast, used for calculating both wrist and shoulder targeting Can toggle whether or not smoothing should be used for the raycast anchor in the Script UI.

  Parameters

  • thumbKnuckle: vec3
  • middleKnuckle: vec3

  Returns vec3

ProtectedcalculateInteractionLocus

• calculateInteractionLocus(thumbKnuckle, indexKnuckle): vec3

• Calculates the interaction locus, where the ray cursor base is placed.

  Parameters

  • thumbKnuckle: vec3
  • indexKnuckle: vec3

  Returns vec3

ProtectedfilterHandZAverage

• filterHandZAverage(cameraToWorld): {
      filteredZAverage: number;
      zAverage: number;
  }

• Calculates the measured and filtered average Z value of stab hand landmarks

  Parameters

  • cameraToWorld: mat4

  Returns {
      filteredZAverage: number;
      zAverage: number;
  }

  • filteredZAverage: number

  • zAverage: number

ProtectedgetCorrectedHandLandmarkPosition

• getCorrectedHandLandmarkPosition(cameraToWorld, avgZ, filteredAvgZ, worldPos): vec3

• Calculates corrected hand landmark positions using the measured and smoothed average Z values of stub

  Parameters

  • cameraToWorld: mat4
  • avgZ: number
  • filteredAvgZ: number
  • worldPos: vec3

  Returns vec3

AbstractgetRay

• getRay(): RaycastInfo

• Update locus, direction, and camera position (or null if required hand landmarks are not tracked).

  Returns RaycastInfo

ProtectedgetRayAlgorithmData

• getRayAlgorithmData(): RayAlgorithmData

• Gets the corrected landmark positions and the device center to world transformation

  Returns RayAlgorithmData

ProtectedgetWrist

• getWrist(): vec3

• Filters the palm landmark if pre-filtering is selected & returns its position in world space This is used to help mitigate the increased jitter for Matador wrist landmarks

  Returns vec3

reset

• reset(): void

• Can be used to reset inner states Should be called when the hand is not tracked or targeting is blocked

  Returns void
