Performance Optimization for Large WebGL Scenes in Creo 11.0

[RC_13238661]

Hi Support Team,

I’m currently using Creo WebGL 11.0 and working with large scenes containing thousands of .ol files. Is there any way to optimize the performance of WebGL scene rendering in this context?

Even though not all nodes are rendered at once, I’d appreciate any recommendations on what aspects can be optimized to improve performance.

Hi @RC_13238661 

Thank you for your question! 

I’d like to recommend to bring more details and context to your initial inquiry. For example:

• What specific performance issues are you experiencing (e.g., slow loading, lag during interaction, memory usage)?
• What browser and hardware setup are you using to run Creo WebGL 11.0?
• Are there specific parts of the scene that are more critical to render in high detail than others?

Please add screenshot(s) to better understand what you are trying to do in your process. 

Please refer to this guideline to make your questions more likely to receive a quick and useful answer.

Q: What specific performance issues are you encountering (e.g., slow loading, lag during interaction, memory usage)?
A: Experiencing slow loading times and frequent out-of-memory errors.

Q: What browser and hardware configuration are you using to run Creo WebGL 11.0?
A: Using the latest version of Microsoft Edge on a system with 64 GB of RAM.

Q: Are there particular parts of the scene that require higher rendering detail than others?
A: The performance bottleneck occurs when attempting to load a large number of .ol files, totaling around 5–6 GB. This significantly increases loading time. Are there any recommended optimization strategies for handling such large datasets?

Hi 

We are looking in incorporating Browser's support for 64 bit WebGL capabilities. There are improvements planned for Creo View WebGL Viewer 12.0 as well Windchill 13.1.1.0 release. You will head about this soon. This will allow you to visualize size large assemblies

In regard with loading performance, there are multiple solutions you can look forward to incorporate - 

- Caching OL file : Creo View Web GL Viewer provides capability to cache OL file, so you dont need to download same data multiple times. 

- Reduce content of OL file - you can use tools like pvsoptimize to reduce size & content of input PVZ based on downstream application. If you are using windchill, then consider using capabilities like multi-fidelity. 

Hope this answers your query.
