Tracking values are reported relative to this origin. The only difference between the Room Scale and Seated mode is the assumed tracking origin. NOTE See Viewpoints for how to create this viewpoint.įor more of a detailed explanation on the coordinate systems, see the next section, Camera. If you need to start the VR experience at a certain point in your scene, such as 1 meter in front of an object, do the following:Ĭreate a viewpoint (Scene > Camera Editor, right-click and select Create > Viewpoint) on the floor of the scene, where you want to stand in VR. See example file OpenVRExample.vpb and How to Start the VR Experience at a Certain Point in a Scene Use a Python script to add behavior to controllers and trackers, for example, to react to button clicks or movement of the tracked device. When a Vive tracker is detected, a simple static geometric representation is rendered at its tracked pose. When a Vive controller is detected, a hand is rendered at its tracked pose. This value can be overwritten in VRED by selecting Visualization > Stereo > Stereo Settings > Eye Separation. Use the hardware slider on the Vive headset to set the distance between your eyes. If SteamVR is not running yet, wait a moment, as it will start automatically. Once installed, click the VR button, at the top of the screen, to install SteamVR. If you haven't installed it, go to and click Install Steam. IMPORTANT You must install the SteamVR software. For an explanation of the coordinate systems, see the Activating OpenVR HMD section below.
