유니티 공식 튜토리얼에 있는 퀴즈 중 VR콘텐츠를 만들 때 필요하다고 생각되는 기본 개념들을 모아보았습니다.
If you are targeting a mobile VR headset (as opposed to a tethered headset), which scriptable render pipeline (SRP) is most appropriate?
The Universal Render Pipeline (URP)
When a VR Device claims to support “6 Degrees of Freedom” (6 DOF), what is “6” referring to?
The 6 degrees of freedom are: Move along x axis, Move along y axis, Move along z axis, Rotate about x axis, Rotate about y axis, Rotate about z axis
Which of the following can be done through the Package Manager window?
Add the XR Interaction Toolkit package, which enables you to more easily develop for VR. Add the XR Plugin Management package, which allows you to deploy to different VR devices.
You have an empty Unity scene with only a Directional Light and a Main Camera in it. What would happen if you added an XR Rig object to that scene?
A new object is added called an XR Rig and the Main Camera is made a child object of the XR Rig object.
Listed below are four types of locomotion that are possible in VR. Which two of these are least likely to induce simulator sickness?
Teleport movement - the user clicks and is instantly transported to a new locationPhysical (Room-scale) movement - the user physically moves in the real world in order to move in VR.
You want to make a ball that the user can grab and throw around the scene. The ball should bounce off of the walls and floor. Which components and properties would the ball probably have?
A Physics Material assigned to the collider. “Use Gravity” enabled in the Rigidbody component. An XR Grab Interactable component with “Kinematic” movement type.
You made a socket interactor for a phone charging dock in VR. However, the phone object is not snapping to the socket. What could possibly explain why this is happening?
The collider does not have “Is Trigger” enabled.
Which of the following is true about mobile vs tethered headsets?
A tethered headset gets its processing power from a gaming console or computer. Some mobile headsets can be plugged in and operate as tethered headsets.
If you set the Spatial Blend property of an Audio Source to be fully “3D”, which two of the following things will happen?
Sound volume will be louder in the user’s ear that is closest to the audio source. Sound volume will increase as the user gets closer to the Audio Source.
In addition to the Spatial Blend property in an Audio Source component, there are additional Audio Spatializer plugins that you can import and enable through the Project Settings. What do these spatializer plugins aim to do?
Apply subtle effects to the volume, quality, and timing of the audio between your left and right ears to make it sound even more like real-world audio.
You have just added a Direct Interactor component to one of your controller objects, expecting to be able to pick up objects directly with your hand. However, when you try to press the grip button near an object, it doesn’t work. Which of the following explanations might be causing this issue?
You forgot to check the “Is Trigger” check box on the Sphere Collider component. The Interaction Layer Mask property is set to “Nothing” The object you’re trying to grab does not have a collider on it.
What does the word “haptics” refer to?
The use of tactile or touch sensations.
Which of the following statements about VR User Interface best practices is true?
Most user interfaces should use the World Space render mode.
Which of the following are true about lighting modes?
Objects must be set to static for lightmapping. Mixed Lighting allows for real-time shadows. To see the effect of Light Probes, you have to bake your lighting.
Which of the following are true about graphic quality optimization in Unity?
Mip maps should be used for high-resolution textures that might be seen from far away. Anisotropic filtering should be used to improve the quality of textures seen at an angle.
