Additional features
Aligning VR and anchor coordinate systems using a VR controller
-
Make sure the VIVE Wave SDK is updated to version 4.4.0 before using the coordinate alignment APIs.
-
Test the APIs before operating your VR simulator to make sure the coordinate systems work as expected.
-
Define the offset of the VR and anchor coordinate systems.
The offset must be defined before the VR and anchor coordinate systems can be aligned. Use the string key ClearRecenterXform to define the offset:
Controller
string key = "ClearRecenterXform"; Interop.WVR_SetParameters (WVR_DeviceType.WVR_DeviceType_HMD, Marshal.StringToHGlobalAnsi(key)); Interop.WVR_SetParameters (WVR_DeviceType.WVR_DeviceType_Controller_Right, Marshal.StringToHGlobalAnsi(key)); Interop.WVR_SetParameters (WVR_DeviceType.WVR_DeviceType_Controller_Left, Marshal.StringToHGlobalAnsi(key));
Wrist tracker
string key = "ClearRecenterXform"; Interop.WVR_SetParameters(WVR_DeviceType.WVR_DeviceType_HMD, Marshal.StringToHGlobalAnsi(key)); key = "ClearRecenterXformTR"; Interop.WVR_SetParameters(WVR_DeviceType.WVR_DeviceType_HMD, Marshal.StringToHGlobalAnsi(key));
-
Calculate the values for the string key used to align the VR and anchor coordinate systems.
The string key PLAYER01InCarOrg is used to align the VR and anchor coordinate systems. Calculate the values for this string key by using the following equation by using the following equation, where T is a meter and q is the quantum angle.
In the following illustration, the anchor coordinate system is offset from the VR coordinate system, following the right-hand rule.
For this setup, the string key PLAYER01InCarOrg would be defined as follows:
PLAYER01InCarOrg = -0.4,0.9,-0.4,0.0,0.0,0.0,1.0
-
Modify the values of string key
PLAYER01InCarOrg as needed and insert it in the following API.
AIO
string key = "PLAYER01InCarOrg=-0.4,0.9,-0.4,0.0,0.0,0.0,1.0"; uint RETURN_SIZE = 256; IntPtr value = Marshal.AllocHGlobal(new IntPtr(RETURN_SIZE)); Interop.WVR_GetParameters(WVR_DeviceType.WVR_DeviceType_HMD, Marshal.StringToHGlobalAnsi(key), value, RETURN_SIZE);
PC VR
string key = "PLAYER01InCarOrg="; string setting = "-0.4,0.9,-0.4,0.0,0.0,0.0,1.0"; key += setting; string result = SendRequestMessage(DeviceType.HMD, key); if (string.Compare(result, "InitMAErr") == 0) { // write your error handling code here }
