Hello,
I wonder whether it's still necessary to have high-end GPU for WebGL mode, since only object data sent to client (as my understanding). Does the Web Server requires GPU on WebGL mode?
You are correct, a GPU is not needed on the server if your models are intended to run in WebGL streaming mode. WebGL streaming became the default mode starting in FlexSim 2020 Update 2.
A model can be toggled to use the video streaming mode. If your webserver will ever stream models in this mode, you'll want to be sure that your server meets FlexSim's graphics requirements. To use video streaming, add a streammode node with a value of 0 to your model tree in MODEL:/Tools/serverinterface/streammode.
You can read more about WebGL and video streaming modes in Webserver (flexsim.com), under the 3D View heading.
There are some limitations with WebGL streaming where some modeling assets are not rendered. Please see Phil's answer here for further explanation.
Could you provide system requirements of WebGL streaming mode?
Perhaps all list requirements without graphics?
@Steven Chen, the Webserver documentation has a System Requirements section:
Webserver - System Requirements (flexsim.com)
Basically it recommends that you start with the FlexSim Recommended Specifications, and increase them even higher depending on the complexity of the models you expect to run and the number of simultaneous instances you expect to run at any given time.
If you expect to never use video streaming mode, no GPU would be needed on your Webserver.
