Sketching is one of the most natural ways for representing any object pictorially. It is however, challenging to convert sketches to 3D content that is suitable for various applications like movies, games and computer aided design. With the advent of more accessible Virtual Reality (VR) and Augmented Reality (AR) technologies, sketching can potentially become a more powerful yet easy‐to‐use modality for content creation. In this state‐of‐the‐art report, we aim to present a comprehensive overview of techniques related to sketch based content creation, both on the desktop and in VR/AR. We discuss various basic concepts related to static and dynamic content creation using sketches. We provide a structured review of various aspects of content creation including model generation, coloring and texturing, and finally animation. We try to motivate the advantages that VR/AR based sketching techniques and systems can offer into making sketch based content creation a more accessible and powerful mode of expression. We also discuss and highlight various unsolved challenges that current sketch based techniques face with the goal of encouraging future research in the domain.

基于草图的内容创建调查：从桌面到虚拟和增强现实

素描是用图形表示任何对象的最自然的方式之一。然而，将草图转换为适用于电影、游戏和计算机辅助设计等各种应用程序的 3D 内容具有挑战性。随着更易于访问的虚拟现实 (VR) 和增强现实 (AR) 技术的出现，素描有可能成为一种更强大但更易于使用的内容创建方式。在这份最先进的报告中，我们旨在全面概述与基于草图的内容创建相关的技术，包括桌面和 VR/AR。我们讨论与使用草图创建静态和动态内容相关的各种基本概念。我们对内容创建的各个方面进行结构化审查，包括模型生成、着色和纹理，最后是动画。我们试图激发基于 VR/AR 的草图技术和系统可以提供的优势，使基于草图的内容创建成为一种更易于访问和强大的表达模式。我们还讨论并强调了当前基于草图的技术面临的各种未解决的挑战，目的是鼓励该领域的未来研究。
