虛擬現實是什麼？戴上頭置式顯示器，你會看到
立體化的3D場景，轉動頭部環顧周圍，然後使用手持
控制器或傳感器四下走動，你可以感受全方位的沉浸
式體驗。除此之外，Unity還是一個功能強大的遊戲
引擎，可以用於構建VR應用，為你的遊戲帶來煥然一
新的交互性。
喬納森·林諾維斯編著的《Unity虛擬現實項目(
影印版)(英文版)》將教授使用Unity進行虛擬現實開
發的方方面面。你將學會如何使用Unity開發特定設
備（如Oculus Rift和Google Cardboard）上的VR應
用，如何同虛擬世界打交道。本書借助生動有趣的項
目向你展示如何構建各種VR體驗。除此之外，你將通
過Unity編輯器和C#來深入學習Unity 3D遊戲引擎。
在本書最後，你將有能力使用Unity設計出內容
豐富的交互式虛擬現實體驗。
