I saw that Clipdrop used three.js to implement Relight effect on their app. I want to implement that lighting effect as well, is it possible to do it using only three.js? (if i already have an image depth map).

P.S. but I don’t want to use image 3D model like in three.js example for pointlights only image depth map as described on Clipdrop [blog](https://clipdrop.co/blog/relight-technicalities)

You could try just applying the depth map to a PlaneGeometry with MeshStandardMaterial, as a [.displacementMap](https://threejs.org/docs/index.html?q=meshsta#api/en/materials/MeshStandardMaterial.displacementMap) 🤔

Yep, displacing vertices in a dense mesh would be enough. Jaume Sanchez did this for demonstrating android depth capture some time ago [GitHub - spite/android-lens-blur-depth-extractor](https://github.com/spite/android-lens-blur-depth-extractor)
