Hi All,
I am new to babylon js and I was looking into creating something like highlight the pointed mess by mouse event something similar to three.js webgl - post processing - Outline Pass (threejs.org)
Any tips, how to would really get me started.
Thank you in advance.
Hello and welcome to the Babylon community! 
We have a lot of tools that make that pretty easy, like Rendering Edges | Babylon.js Documentation (babylonjs.com), and Highlighting Meshes | Babylon.js Documentation (babylonjs.com) 
Thank you very much , I will take a look into those
Hi @carolhmj
I tried edge rendering, but for sphere is does not work correctly
does it support only some geometry types?

Thank in advance

Hi @carolhmj
I have done something similar to the three js here: SamplePlaygroudUP_Selection | Babylon.js Playground (babylonjs.com)

Can you please take a look and suggest some ways?
Thank you very much, you have been supporting a lot to understand how the babylon js works
