 # BA_PointCloud
-PointCloud-BachelorThesis
+Forked from : https://github.com/bloc-in-bloc/BA_PointCloud
 
 Project files for my bachelor thesis on rendering large point clouds in Unity.
 
+This project is meant to be used to contribute to this repository and keep a version of BA_PointCloud in case of deletion/archiving.
+
+We want to contribute on the PotreeV2 format :
+- Be able to use a remote url
+- Be able to use different encoding of PotreeConverter 2.0 (mainly Brotli)
+
+# Remote URL
+
+We would like to use the PotreeV2 format for remote url, mainly because we might have to handle several Go of data.
+
+## Remote/local URL handling with v1/v2 version
+
+For this we had to transform the URL given to the Cloud loader :
+
+Potree1 : 
+Clouds/Lion -> Clouds/Lion/cloud.js
+https://remoteurl.com/Lion -> https://remoteurl.com/Lion/cloud.js
+
+Potree2 : 
+Clouds/Lion2 -> Clouds/Lion2/metadata.json
+https://remoteurl.com/Lion2 -> https://remoteurl.com/Lion2/metadata.json
+
+We did this so codebase can handle in a easier way the remote/local and v1/v2 cases.
+
+## Range request
+
+We have to do range request to get the part of the remote file we want, so we're using range request as Potree is doing.
