您可以创建空间锚这样
var anchor = SpatialAnchor.TryCreateRelativeTo(UrhoAppView.Current.ReferenceFrame.CoordinateSystem, new System.Numerics.Vector3(x, y, -z));
store.TrySave("anchorname", anchor);
注意,乌尔禾有一个左手坐标系统,同时HoloLens API,因此有一个右手坐标系统中的Z轴负。
您可以将锚映射到当前的系统是这样的:
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
}
