XRDepthInformation: normDepthBufferFromNormView property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The read-only normDepthBufferFromNormView property of the XRDepthInformation interface contains the 3D geometric transform that needs to be applied when indexing into the depth buffer.
Value
An XRRigidTransform that needs to be applied when indexing into the depth buffer. The transformation that the matrix represents changes the coordinate system from normalized view coordinates to normalized depth-buffer coordinates that can then be scaled by depth buffer's width and height to obtain the absolute depth buffer coordinates.
Examples
Use XRFrame.getDepthInformation() (CPU) or XRWebGLBinding.getDepthInformation() (WebGL) to obtain depth information. The returned objects will contain the normDepthBufferFromNormView of the depth buffer, which you can use for further calculations.
const normDepthFromNormViewMatrix =
depthData.normDepthBufferFromNormView.matrix;
const normViewFromNormDepth =
depthData.normDepthBufferFromNormView.inverse.matrix;
