<div class="paragraph"><p>jMonkeyEngine 3 has a wide range of support for Virtual Reality (VR). The known supported systems are:</p></div>
<div class="paragraph"><p>HTC Vive and systems supporting SteamVR/OpenVR</p></div>
<div class="paragraph"><p>Native Oculus Rift support (and through SteamVR)</p></div>
<div class="paragraph"><p>Razer HDK and systems supporting OSVR</p></div>
<div class="paragraph"><p>Google Cardboard / GoogleVR</p></div>
<div class="paragraph"><p>Two implementations exist for OpenVR. A community maintained JNA based binding and LWJGL&#8217;s JNI based.</p></div>
<div class="paragraph"><p>To use the JNA based bindings, put:</p></div>
<div class="literalblock"><div class="content"><pre>settings.put(VRConstants.SETTING_VRAPI, VRConstants.SETTING_VRAPI_OPENVR_VALUE);</pre></div></div>
<div class="paragraph"><p>in your settings. To use LWJGL, instead put:</p></div>
<div class="literalblock"><div class="content"><pre>settings.put(VRConstants.SETTING_VRAPI, VRConstants.SETTING_VRAPI_OPENVR_LWJGL_VALUE);</pre></div></div>
<div class="paragraph"><p>Note that the LWJGL bindings require LWJGL3 (jme3-lwjgl3) to be used.</p></div></div></div>
