I'm taking an augmented reality course and the topic of the final project is free for us to decide but it had to be approved by the professor. however the tools we use are entirely up to us.
My project had the following requirements:

Use facial recognition to place sunglasses on the users face

The user needs to be able to switch between sunglasses models via gesture or marker

My professor recommended me Lens Studio for this. However I failed to find a tutorial that teaches the tools without using the premade templates and I'm starting to feel like it isn't the right tool. And I'm reaching to this platform hoping to find someone that has either, a better tool for this or a more in depth tutorial for lens studio. I'm even willing to make it directly with Python + opencv if I find the right guide for the job. Thanks a lot for your time
