I provide a scene to show my customer’s products. for example, customer A and customer B. And they provide product and a simple description for the product. customerA provide: product1 model with some description to the product1 model; product2 model with some description to the product2 model; …

Ok I guess you could use something like this :slight_smile: https://playground.babylonjs.com/#P89ASS This is based of our gizmo which can already be stable in size on screen. Let me know if that can work.

Hi 99999, If you genuinely want the sphere to be a piece of in-scene geometry at a constant screen-space size, you can scale it frame-by-frame based on how far it is in front of the camera. The Gizmos do something similar to this, though I’m not sure that logic is quite correct; that logic appears …

Thanks! Your suggestion is very helpful！ When I use the sphere as Gizmo, it can’t adapt to position when mousewheel。 so I dynamic scale the sphere’s size. And I edit one sphere( the bottom one) in the scene, and the code: https://playground.babylonjs.com/#S3FFNK#3 and some of the code is from …

Just a random thought - you could use two cameras, one with the scalable meshes, that is attached to the canvas for user input, and the other fixed, that just renders stuff. I guess the issue with this approach is that you can’t control the render order of the meshes (it will be fixed for the camer…

I think it’s similar with the Gizmo。When mousewheel，the sphere is fixed， but the product is scaled， it looks like the distance is changed from the sphere to the product。

[image] It is what I want to achieve, and can I achive this without too complicated method in babylon.js？

Would the default Babylon Gui Features not be ok for this ? https://www.babylonjs-playground.com/#XCPP9Y#3194 https://doc.babylonjs.com/how_to/gui#tracking-positions

[image] [image] Yes, I had tried to use the tracking gui method, but there is a problem： I want to hide the corresponding circular button(marked red in the picture) when the emphasized part in the model( I think is the right arm in the picture) is turned behind the screen， but I do not know how t…

ohhhh I see, and it has been a recurring ask as I can see this week. Let s see how we could easily do it playing with scaling depending on the distance from the camera.

Yes, perfect, this is exactly what I want. Thanks very much!
