LWJGL 3.3.3 · org.lwjgl.openxr.XrHandTrackingMeshFB

A container of mesh data.

Description

All arrays are application-allocated, and all may be NULL if any of jointCapacityInput, vertexCapacityInput, or indexCapacityInput is 0.

The data in a fully-populated XrHandTrackingMeshFB is immutable during the lifetime of the corresponding XrInstance, and is intended to be retrieved once then used in combination with data changing per-frame retrieved from LocateHandJointsEXT.
