Feature Description

This feature allows you to remove a green screen or a blue screen from your volumetric video using the Vlahos formula.

How to Use

1. To use this feature in Export or Rendering you must enable the feature’s main toggle.
   
2. The Vlahos formula provides two optional values, and we added a third for further thresholding because pointclouds don’t support transparency.
3. The first value A1 represents the how much should the algorithm take green/blue screen into account, where higher values mean higher importance for the screen removal.
   
4. The second value A2 represents the balance between green and blue colors, where if this value is 0 then it will look for purely green colors, and if this value is 1 then it will look for purely blue colors.
   
5. Finally there is the Threshold value. After applying the Vlahos formula, we get transparency values between 0 and 1. So with this threshold value we set at what level of transparency do we want to keep our points within the pointcloud.
