i try to convert txt format point cloud(e.g format: x y z r g b) to 3D Tiles (.pnts),it successed,but in Cesium,when I want to zoom out, it disappered. and next problem is ,what is the format of xyz?when i convert ,the position is wrong ,totally strange. i use WGS84Plane coordinate system，like 2552604.4 187598.9 0.0 6 18 24 2552604.4 187599.9 0.0 56 25 188 2552604.4 187600.9 0.0 232 77 222 2552604.4 187601.9 0.0 78 60 161 2552604.4 187602.9 0.0 180 215 55 2552604.4 187603.9 0.0 141 171 189 2552604.4 187604.9 0.0 142 216 27 this position is in China

Hi @whuxxie, what command did you use to convert your pointcloud?

i use py3dtiles convert point.xyz --out /tmp/destination

hi @whuxxie, what CRS your point.xyz is in? If you don't know, you can give the first 10 or so points.

Short story, you need to use --srs_in <your_crs> and --srs_out 4978
