I’m having issue on reprojecting the vertices following this Support tiling georeferenced 3D models into 3D Tiles - #3 by omar
this is the python function(using pyproj) that I use for re-projection from epsg 6677 to epsg 4978(which is ecef on wgs84).
def _convert_proj2ecef(self, proj_xyz): crs_proj = CRS.from_epsg(self.epsg) crs_4978 = CRS.from_epsg(4978) transformer = Transformer.from_crs(crs_proj, crs_4978) return transformer.transform(proj_xyz, proj_xyz, proj_xyz)
However, the model will be tilted like this, which should be overlaid to point cloud.
Any idea what is wrong?
