Thousands of tiles' tilt model browsing speeds up, saying goodbye to the embarrassment of jumping out one by one

0. Source of problem

stay Context Capture Or the tilt model data produced by Dajiang Zhitu is large , There are thousands of root nodes . The loading process not only takes up a lot of computer memory , And the loading speed is slow .

Look at the effect （3000 Sample data for multiple nodes ）

Before lightweight merge ：

  After lightweight merging ：

 1. Principle analysis ：

During data loading , You need to traverse every root node to load , Too much data will cause slow loading . therefore , In the new earth “ hold-all ” There is “ Merge the root node ” This function , This function is mainly used to extract and analyze the current loaded data node layer by layer to get a new root node , Until there is only one root node .

2. The operation process ：

Open the New Earth software , Click on hold-all --> Merge the root node

 

Select the tilted model data folder where you want to merge the root node , The automatic generation is named MergeRoot Folders and MergedRootNode Of .lfp file , The path where the file is saved and the folder where the merged data is selected are under the same level directory , And cannot be modified , Generally, other parameters can be kept as default .

  Be careful ： Generated after merging MergeRoot The location of the folder and the original data should remain unchanged , No data can be deleted . The original lightweight of the tilt model is only the consolidation and analysis of nodes based on the source data , Improve indexing efficiency , Do not modify the source data itself .

 3. View generation results

In the same category , Generative MergeRoot The folder and MergedRootNode.lfp file

  After merging the root nodes , Open the newly generated lfp Data can be loaded in seconds .
