If you add objects to your planning afterwards, simply click on Force sync to transfer them to the virtual reality. It is the same procedure to remove objects.

To show changes of your planning immediately at every stage, simply click on Synchronize VR in realtime in the settings menu.

3.3 Settings

Figure 21: “Settings” Dialog of the Plugin ‘VR-Viewer’

3.3.1 General

You will see object changes like color adjustments in your VR headset immediately after they are finished, if you activate Synchronize VR in realtime. If you move the object inside the virtual environment, this setting will be deactivated automatically to prevent problems with the pCon.planner PRO.

By choosing Attach Powerwall to active viewport you start from the same position within the Powerwall as you do by looking at the desktop.

If you have a Powerwall and you choose Powerwall default start, then both Powerwall and Headset will be acti- vated on starting the plugin.

3.3.2 Appearance

The following options are available:

1. Ambient Occlusion active: The shading method enables realistic shading in the room with a short ren- dering time. It is set by default. 2. Shadows active: The pre-set light source (artificial sunlight) offers natural-looking shadows from objects. It is also set by default. 3. Grid active: If enabled, the grid (on level 0) will be shown within the VR scene.

You can change these settings while another person is looking at the planning in virtual reality. Add or remove the functions by simply clicking Show in VR.

3.3.3 Camera

Instead of using the world coordinate system {WKS} you are now able to choose an individual starting point inside your planning. Set a Start Camera, select it at the dialog Settings and apply it. This position is valid for the glasses as well as for the Powerwall. As soon as you change the name of a camera in pCon.planner, the change instantly appears also in VR.

If more than one camera is included in your planning, simply change your position by selecting another camera in the Settings dialog of the pCon.planner. The user of the VR headset switches to another camera with the controller by choosing Next Camera in the menu {Navigation}. The world coordinate system cannot be chosen with the controller.

4.4.1 Calibrating the Powerwall

The prerequisite for the use of the interactive Virtual Reality wall is the correct positioning of the HTC VIVE base stations that should be found to the left and right of the Powerwall. In addition, ensure that the room calibration from the SteamVR is also valid.

Figure 39: Example of the Arrangement for an Efficient Use of the Powerwall

Figure 40: ‘Room Setup’ Menu

Click on Calibrate Powerwall and confirm the question by choosing ‘Yes’, if you would like to really calibrate the Powerwall.

Figure 41: Query for Calibration of the Powerwall

The alignment process starts immediately. Please do the following:

1. Turn on the controller, if it is not already active. 2. With the controller, tap the corners of the screen in the following order: “Top left – bottom left – right” and press the control button to set the individual control points 3. Once you have set the individual points, the Powerwall will open on a second monitor of your choice. The controller should be visible on the monitor. Using this you directly move with Hover-Mode (see chapter 4.2).

Figure 42: Display of the Planning as Well as a Section That Will be Displayed to the Viewer on the Powerwall

When calibrating the Powerwall, the following settings can be selected:

1. Mode: In addition to Mono (2D), Side-by-side and Top-down are available. 2. Viewport: Depending on your position in front of the Powerwall, you can set two important parameters. 1. Height: For the optimum view of your planning, the viewing height will be measured from the bottom edge of the Powerwall. Since the height of the viewers will vary, an average value should be used. 2. Distance: This parameter determines the distances between you, or the viewer, and the screen. A distance of 1 to 1.5 meters is ideal.

Now you and all other users will be able to open and explore your planning in virtual environment, through the headset or on a separate monitor.
