sample method

void sample(double time, Pose pose)

Writes every channel's value at time (seconds, clamped to the keys) into pose. Nodes the clip doesn't move are left as they are.

Implementation

void sample(double time, Pose pose) {
  final value = _scratch;
  for (final channel in data.channels) {
    if (channel.node >= pose.nodeCount) continue;
    final sampler = data.samplers[channel.sampler];
    _sampleInto(channel.sampler, sampler, time, value);
    final n = channel.node;
    switch (channel.path) {
      case AnimationPath.translation:
        pose.translations[n * 3] = value[0];
        pose.translations[n * 3 + 1] = value[1];
        pose.translations[n * 3 + 2] = value[2];
      case AnimationPath.rotation:
        pose.rotations[n * 4] = value[0];
        pose.rotations[n * 4 + 1] = value[1];
        pose.rotations[n * 4 + 2] = value[2];
        pose.rotations[n * 4 + 3] = value[3];
      case AnimationPath.scale:
        pose.scales[n * 3] = value[0];
        pose.scales[n * 3 + 1] = value[1];
        pose.scales[n * 3 + 2] = value[2];
      case AnimationPath.weights:
        break;
    }
  }
}
