Forum Post: How to compute right transform matrix using coodinate from xml file from ContextCapture

Hi, I know CC could ouput the product to 3dTiles format for CesiumJS, and what I am doing is developing a tool which could convert osgb files produced by CC to 3dTiles. The problem is that the tileset converted from my tool could not overlay exactly with that produced by CC, seems there remains an rotation (as the image shows, the wall will get crossed ). So most likely the"Transform" of the tileset.json I computed is wrong, the way of mine is fristly transform the position of the coordinate from matadata.xml to WGS84 (EPSG Code:4326), and then use the position to compute ENU matrix *** I treat as the transform matrix. Is that all right? anything I have missed up?
