Product Brief
Opt Loader converts the geometry and material data in GLzip format, open format 3D models and GIS models exported by Opt plugin into proprietary high-performance lightweight mesh models by simplifying and optimising them with professional algorithms. In three.js, cesium and other 3D rendering libraries runtime to achieve high-performance loading and rendering (than open-source performance can be increased by more than 10 times).
Advantages
High loading and rendering performance
One-to-one correspondence between model geometry and part/component attribute data.
Free distribution and application
Convenient for secondary development

FAQ
Frequently asked questions are in the form of lists (with questions and answers, support for fuzzy keyword searches), and can be maintained in the background;
The current list of questions and answers are as follows:
1. Q: What are the precautions when compressing Osgb model into zip file?
A: Please put the complete data of Osgb model into the same folder and compress the folder into zip format, which requires the folder name to be in English or mixed alphanumeric, and the folder name to be the same as the zip file name.
Note: The complete data of tilt photography includes Data directory (contains the osgb data of hierarchy) and xml file (osgb configuration file), different tools may have other files at the same level of Data directory when generating, packing at the same time will not affect the data integrity.
Some Osgb models are composed of Block** folders, when compressed into zip format, first create a Data folder, put these Block** folders into the Data folder, then create a parent folder, put Data and .xml files into it, and compress it into zip file format.
2. Q: Are there any precautions or rules when compressing models in other formats into zip files?
A: For models in other formats that need to be compressed into zip files, when compressing, please place the model files and related files together in a folder and compress them into zip format, with the same name of the main model file, the folder name, and the name of the zip file. For example, the shp format shown below:
3. Q. How to deal with the missing parts (as shown in the figure below) after converting the Revit model to other formats?
(original model)
(converted model)
A: The possible reason is that there is an error in instantiating some components in revit, please turn off the instantiation option in the parameter setting panel page of Opt Plugin for revit, re-export the glzip file and upload it to Opt Converter for conversion.
