XRDepthInformation
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only insecure contexts (HTTPS), in some or allsupporting browsers.
Experimental:This is anexperimental technology
Check theBrowser compatibility table carefully before using this in production.
TheXRDepthInformation interface contains information about the distance from the user's device to the real-world geometry in the user's environment.
This interface is the parent of:
XRCPUDepthInformationDepth information from the CPU (returned by
XRFrame.getDepthInformation()).XRWebGLDepthInformationDepth information from WebGL (returned by
XRWebGLBinding.getDepthInformation()).
You will usually interact with these child interfaces. However,XRDepthInformation provides some useful properties that are inherited:
Instance properties
XRDepthInformation.heightRead onlyExperimentalContains the height of the depth buffer (number of rows).
XRDepthInformation.normDepthBufferFromNormViewRead onlyExperimentalAn
XRRigidTransformthat 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'swidthandheightto obtain the absolute depth-buffer coordinates.XRDepthInformation.rawValueToMetersRead onlyExperimentalContains the scale factor by which the raw depth values must be multiplied in order to get the depths in meters.
XRDepthInformation.widthRead onlyExperimentalContains the width of the depth buffer (number of columns).
Instance methods
None.
