Mesh Count of 3D Models

With the FineVis Data Visualization plugin installed, you can upload GLB models to the 3D City Scene and Custom 3D Scene components to add model objects.

However, after models are added, issues such as lag and application crashes may occur. In such cases, you can refer to this document to optimize models.

Mesh count refers to the number of independent meshes contained in a GLB model file. High mesh count of GLB models may impact the performance of the application using the models.

In a 3D modeling software, the mesh count roughly tracks with the number of independent objects. Generally, the more independent objects your scene contains, the more meshes will be exported to a GLB file.

However, you can reduce the mesh count by merging objects, thereby minimizing the negative impact on FineReport performance.

When designing FVS dashboards, if uploaded models contain an excessive number of meshes, model rendering may lag, thereby affecting template performance.

Note: 

You are advised to keep the mesh count of a single model or the total mesh count of all models in a 3D scene below 3,000.

Common performance issues are as follows:

1. Noticeable lag occurs when models are uploaded into a scene for editing.

2. The template functions normally when models are uploaded and used individually. However, noticeable lag occurs when the models are copied and used together.

3. Noticeable lag occurs when you use some seemingly simple models, rather than the more complex ones.

4. The following prompt is displayed in the Model Check window:

Note: 

If you encounter the issues mentioned above, you are advised to merge objects in a 3D modeling software to reduce the mesh count, and then re-upload the model to the FVS dashboard.
