Module 5 Overview模块 5 概述
Overview 概述
In the previous modules, you have learned how to convert your ideas into sketches and 3d models. The next question you might have is how to create a 3d model from a physical object. Maybe you want to create a replacement part, or sculpted a part in clay and want to modify that digitally or just create a bust of your friends. In this module we will cover different technologies for turning objects into 3d models. The devices we will demonstrate are the next engine 3d scanner, Microsoft Kinect, structure sensor, as well as any camera you have (including your phone).
在之前的模块中，你已经学会了如何将你的想法转化为草图和 3D 模型。你可能接下来会问如何从实物创建 3D 模型。也许你想制作一个替换部件，或者用粘土雕刻一个部件并想对其进行数字化修改，或者只是制作你朋友的头像。在本模块中，我们将介绍将物体转化为 3D 模型的不同技术。我们将演示的设备包括 Next Engine 3D 扫描仪、Microsoft Kinect、结构传感器，以及你拥有的任何相机（包括你的手机）。
