Model statistics

[BorisKourt]

I wasn't able to find if there is any internal implementation for this.

Is there a way to get some basic statistics for the model, like draw calls, polygon count, and number of materials?

I have been using the frontend version of: https://github.com/donmccurdy/glTF-Transform but it is overkill for this, and doesn't have some statistics like draw calls.

Hi @BorisKourt, thanks for reaching out. You can use our editor. https://modelviewer.dev/editor/

Once you select or load a model, click on the info button under Validation Report. We use KhronosGroup/glTF-Validator to give such statistics.

Thanks! I was hoping to be able to do it programmatically. Since I have model-viewer embedded in my application. I will try to dig through your implementation of KhronosGroup/glTF-Validator wasn't able to get it to work myself.

Is the editor in this repo as well?

yes, it's the space-opera package. I believe this file should help you: https://github.com/google/model-viewer/blob/master/packages/space-opera/src/components/model_viewer_snippet/components/validation_utils.ts
