An essential part of exploring your 3D files is the ability to easily and intuitively navigate. At IrisVR, we've designed a navigation system that accommodates any 3D file and gives the user the ability to almost instantly travel to any place they'd like.
The HTC Vive is great for creating a full room virtual reality experience. You can walk, bend down and turn around in VR all in real-time.
With the Oculus Rift, if you haven’t purchased the additional sensors for room-scale VR, you can still get an immersive experience from your desk. Don't forget to look around with your actual head and interact with the virtual world using the Oculus Touch.
Teleportation is the foundation of our navigation system. Whenever pointed, the Navigation Wand will display a cursor that has two states. 1) Enabled and 2) Disabled (displays “X”).
The cursor becomes disabled when it is pointed at something it cannot teleport on to or when it detects clashing with the player.
By pressing the HTC Vive’s back trigger button or Oculus Rift’s action button while your cursor is enabled, you will teleport to the cursor's location. For the most precision, look at a point on the ground or floor where you would like your feet to land.
With the HTC Vive, you are free to move your whole body just like you would naturally. The base stations track your height and movement to create a smooth experience within virtual reality.
For the Oculus Rift, IrisVR has designed Prospect to not allow the user to turn smoothly or strafe. If you'd like to perform these motions we recommend using the HTC Vive. Instead, our Oculus navigation system rotates the player in increments of 30 degrees by tapping left and right on your controller (right thumbstick) or keyboard ("A" and "D").
With the HTC Vive walking is accomplished by actually taking short physical steps while in your designated tracking area. For the best experience, we recommend using these short physical steps in conjunction with the teleport feature of the navigation wand designed for longer distances, i.e. moving down a hallway.
The player can walk forward and back to cover smaller areas or ascend and descend stairs using the Oculus Rift. Caution: any motion while standing or seated in real life may cause vestibular discomfort. To walk, use the left controller joystick or tap "W" or "S" on the keyboard.
It is currently not possible to “fly” over your imported model while in VR if using the HTC Vive. If flying is a particular feature you are interested in, check out the Oculus Rift.
With the Rift, you can ascend or descend during your walkthrough by using the up and down arrow keys or squeezing the back triggers on a gamepad. Flying is an excellent way to get a bird's eye view of a project or move between floors without relying on the stairs.
Scale Model Mode
You can also jump to any position within a model via scale model mode by navigating to the "home" icon on the toolbar.
Pressing the menu button will toggle on tooltips for your motion controllers while you’re in VR with Prospect. Press the menu button once more to turn the tooltips off.
Entering a Building, Door or Solid Object
After teleporting into your selected area you will often want to enter the model through a door or window. For example, with the HTC Vive, if you are on the outside of a door, extend the arm holding the navigation wand through the door until you can no longer see the remote in your hand. Then click the trigger of the navigation wand to be teleported inside that space.
With the Oculus Rift, you can only travel through elements by enabling Ghost Mode. To do this: tap Y on the gamepad or the Right Arrow key on a keyboard. When Ghost Mode is enabled there will be a black vignette around the periphery of your view.
Real World Boundaries
As you move around within virtual reality with the HTC Vive, a blue grid will appear if you are approaching the edges of tracking space (established during SteamVR setup). Make sure to calibrate this setup each time you adjust your room layout for safety.
