您可以像这样创建空间锚点
var anchor = SpatialAnchor.TryCreateRelativeTo(UrhoAppView.Current.ReferenceFrame.CoordinateSystem, new System.Numerics.Vector3(x, y, -z));
store.TrySave("anchorname", anchor);
请注意,Urho 有一个左手坐标系,而 HoloLens API 有一个右手坐标系,因此是负 z。
您可以像这样将锚点映射到当前系统:
var matrix = store["anchorname"].CoordinateSystem.TryGetTransformTo(UrhoAppView.Current.ReferenceFrame.CoordinateSystem);
if (matrix.HasValue)
{
System.Numerics.Vector3 scale;
System.Numerics.Quaternion rotation;
System.Numerics.Vector3 translation;
System.Numerics.Matrix4x4.Decompose(matrix.Value, out scale, out rotation, out translation);
var q = new Quaternion(rotation.X, rotation.Y, rotation.Z, rotation.W);
var v = new Vector3(translation.X, translation.Y, -translation.Z);// -Z Right-handed to left-handed
}
