Class DepthPreprocessor

Namespace
Uralstech.UXR.QuestMeshing

Script that will preprocess depth data for meshing.

public class DepthPreprocessor : DontCreateNewSingleton<DepthPreprocessor>
Inheritance
object
DepthPreprocessor

Remarks

This script by itself does very little. It is meant to be used with shaders which utilize the data exposed by this script and with other scripts from this package, like DepthMesher and CPUDepthSampler.

This directly conflicts with Meta's EnvironmentDepthManager and any other script that acquires the depth textures using XROcclusionSubsystem.TryGetFrame, potentially including Unity's AROcclusionManager. This script automatically populates the following global shader variables, to keep some compatibility with EnvironmentDepthManager:

  • _EnvironmentDepthTexture
  • _EnvironmentDepthReprojectionMatrices
  • _EnvironmentDepthZBufferParams
  • _PreprocessedEnvironmentDepthTexture

The following custom global shader variables are also defined by this script:
  • _EnvironmentDepthInverseReprojectionMatricesThe inverse of _EnvironmentDepthReprojectionMatrices, used to convert points from the current depth texture frame into world space.
  • _EnvironmentDepthProjectionMatricesProjection matrices for the current depth texture frame.
  • _EnvironmentDepthViewMatricesView matrices for the current depth texture frame.
  • _EnvironmentDepthWorldPositionsTextureTexture containing world-space positions from the XR depth texture (computed for the left eye).
  • _EnvironmentDepthWorldNormalsTextureTexture containing world-space normals from the XR depth texture (computed for the left eye).
