// Calculator fills in only rotation of the joints leaving visibility undefined.

// Input:
// TENSOR - std::vector<Tensor> with kFloat32 values
// Vector of tensors to be converted to joints. Only the first tensor will
// be used. Number of values is expected to be multiple of six.
//
// Output:
// JOINTS - JointList
// List of joints with rotations extracted from given tensor and undefined
// visibility.

// Example:
// node {
// calculator: "TensorToJointsCalculator"
// input_stream: "TENSOR:tensor"
// output_stream: "JOINTS:joints"
// options: {
// [mediapipe.TensorToJointsCalculatorOptions.ext] {
