Release 0.3.4

Features

• Added improved render path that reads generated depth maps directly in the pixel shader. This can improve performance significantly and scales better with larger depth maps.
• Added support for supplying a reversed alpha channel using the XR_EXT_composition_layer_inverted_alpha extension. This enables Unreal Engine 5.6 to support alpha blended passthrough without custom postprocess materials.

• Added option to use both the application alpha and chroma key masking at the same time.
• Added slider to scale up the depth map relative to the disparity map.
• Added depth contour filtering. This is designed to combat gradient artifacts when sampling low resolution depth maps.
• Added more debug visualization modes and parameters to the menu.
• Added maximum confidence adjustment for disparity filtering.

Bug fixes

• Improved rendering in many ways.
• Added double buffering for settings menu.
• Fixed depth testing being disabled when writing deferred depth map, leading to occluded areas being drawn over foreground.
• Fixed depth folding being applied into areas with high confidence instead of areas with low confidence.
• Many misc. fixes.

Misc

• Updated OpenXR SDK to 1.1.48.
• Set the stereo mode to 3D projection on first launch if compatible headset is detected.
