A 3D scan/sonar-like post-processing effect. Essentially a visualization of a spherical signed distance field (SDF) rendered using the scene's depth and colour buffers. Multiple scans are supported without image-effects, and one that works with image effects (other post-processing effects). If you're using URP, you get the best of both worlds and can have multiple scans with post-processing.

Note: For single-pulse scans, please switch to the 'urp' branch, which has an experimental system for just that.

• Built-in pipeline URP.
• Tested with Unity 2019.4 (LTS).
• Can be edited using Amplify Shader Editor.

You'll find everything under Mirza Beig/Post-Processing Scan/...

1. Attach CustomPostProcessing to your camera, and assign one of the included Post-Processing Scan materials (or make your own).

2. Attach PostProcessingScanOrigin to any object whose position you want to track as the scan origin. Assign the scan material.

Use Unity's Post-Processing Stack v2 and simply add the effect.

Instead of attaching a script to the camera, add CustomRenderPassFeature to your URP pipeline asset renderer and assign the material there.
