1. A VR Introduction

The WOW! effect The “Huh” effect Why develop for Google Cardboard? Insights on the VR market My forecast for the next years Tooling and workflows

Unity (5.1) 3D Authoring - Blender Makehuman About workflows Hardware

What can VR bring that flat worlds cannot?

Ambiance Immersion Presence and attachment

The Cardboard platform

Reality versus virtual reality The mobile platform The mobile VR adopters Hardware Restrictions / Limitations

2. Alien Apartment

How did I come to develop Alien Apartment? Let’s build on this knowledge and craft a world!

Setting things up Managing axis Kicking in stereo view Updating player azimuth Movement detection principle (triggering events with your head) Theory Implementation Usage Last considerations Making user interfaces and interactions without actual interfaces

Basics Running an example

Can I make a user interface out of it?

Creating ambiance

Skyboxes and the Lighting window Calling for emotions and memory Audio Music What have we done here?

Miscellaneous tips and tricks

Light-mapping Performance Clipping planes Batching Meshes merge Occlusion baking Playing with the brain Quality settings Physically-based Shader Fading Keystore Version control Awake(), Start(),... Generic coroutine management Building Exit on back key press Screen time-out Shaders Unlit with alpha Self-lit shader Glass shader Textured glass shader

Summary

3. Glitcher VR

Introduction to Glitcher VR

Prior experience and motivation

The challenges of VR development Glitcher VR Architecture Deconstructed

Camera Subsystem Problems that need to be addressed by the camera subsystem Starting and stopping cameras Sending frames to the GPU for fast processing

Creating a drawing surface

Saving photos, capturing filtered frames, and video Automatically detecting and managing cameras with a camera manager

Input subsystem

Problems that need to be addressed by the input subsystem Detecting and handling input devices Speech as an input multiplexer Rendering and Filter System Design goals Basic filters Building complex filters from a base filter Rendering additional assets Filter manager

Notification System

Design goals Building a text renderer Building a basic notification

Scheduling notifications with a notification scheduler

Helper utilities and other features

Torch/Flashlight

Setting up face detection

Converting face bounding boxes to GLSL coordinates Sending face information to the filters

Tips and Potential Improvements

Improvements to input Avoid filler content Testing with ordinary users Testing on various hardware Memory management and using profiling tools

Summary

4. Lanterns and a Village for Cardboard

Common VR rendering techniques used in both apps

Adapting a scene for VR Creating our own renderer Using renderer from the Cardboard SDK for Android

Rendering a scene in the Lanterns VR app

Fixed draw order optimization Fog and light shader Water reflection Night sky shader

Rendering and optimizations tricks in the Village VR app

Single draw-call smoke effects Point sprites for fireflies and snow Sorting objects by distance Frustum Culling Characters movement Reusing textures and atlasing Lightmaps packing Lightmap palettes Final Village Shaders Vegetation shaders Sky textures compression

Summary

5. Google Cardboard - VR for the Masses

The Google Cardboard project Getting started with Cardboard

Previous Astronaut games The story of WAA! VR

Getting started on WAA!

Unity3D pro Testing device Nexus5 Cardboard kits Asset development in Maxon Cinema4D R16 Asset export: FBX or C4DtoUnity?

The Google Cardboard Unity3D SDK

Moving from .js to c\

Interaction concepts

The magnetic trigger Raycast collision testing

UI, menus, and scene setup

Skybox and “space” environment “Title” screen Main “Universe” menu In-game HUD

Firing and hitting in VR space

Adding “Asteroids” as targets Firing rockets VR 3D effect and the “zone” Avoiding VR sickness

Special effects, polishing, and testing

Everything looks better with particles Trail renderer Adding powerups Tweaking the gameplay parameters Adding the character’s body
