**课程名称：Blender写实渲染：将3D模型添加到图像中** **课程概述：** 本课程将教授您如何将3D模型无缝地融入真实照片，以达到逼真的效果。您将学习的关键步骤包括： 1. **相机匹配：** 利用fSpy工具精确匹配Blender相机与实拍照片的相机透视，确保3D模型与真实场景的比例和角度一致。 2. **场景构建：** 在Blender的3D空间中添加3D模型和作为基础的平面对象。 3. **光影互动：** 学习如何让3D模型在平面对象上投射出逼真的阴影，并在必要时添加反射效果，使模型看起来真实地“存在”于图像表面。 4. **渲染与合成：** 学习使用节点编辑器在合成窗口中进行后期处理，包括渲染层和集合的使用，最终将合成的图像渲染输出。 **您将掌握的技能：** * 使用fSpy精确匹配相机透视 * 在图像表面形成逼真的阴影 * 在图像表面形成逼真的反射 * 熟练运用Blender的节点编辑器进行合成 * 掌握渲染层和集合的使用 * 输出高质量的渲染图像 **课程目标受众：** 本课程适合已有一些Blender使用经验的3D艺术家。如果您是初学者但学习动力十足，同样非常适合本课程。课程中使用的Blender和fSpy软件均为免费软件。 **课程亮点：** 课程包含两个实践练习，帮助您巩固所学技能： * **练习一：** 将一个3D时钟模型添加到墙面图像中，并使其在墙上投射阴影。 * **练习二：** 将三个3D咖啡杯模型放置在玻璃桌面上，并使其同时产生阴影和反射。这部分将重点讲解如何使用不同的渲染层以及在合成窗口中利用节点编辑器进行叠加。 **课程价值：** 完成本课程后，您将能够将任何3D模型灵活地添加到各种图像的表面，为您的作品增添真实感。这项技能在许多领域都有广泛应用，例如，您可以用它来为虚拟样板房添加逼真的3D家具模型，极大地提升空间展示效果。
Learn to add a 3D model to an image! The first step is to get the perspective of the camera in Blender to match the perspective of the actual camera on which the photo was taken. After that, the 3D model and a plane object will be added to the 3D space. The next step is to make the 3D model form a shadow and, if necessary, a reflection on the surface of the plane object so that they appear to be on top of a surface that is in the image. This makes the end result as realistic as possible. Lastly, an image of the view is rendered.Skills you will learn:using fSpy to define the right perspective for the cameraforming a shadow on a surface in an imageforming a reflection on a surface in an imageusing the node editor in the Compositor windowusing rendering layers and collectionsrendering the view into an imageThis course is meant for 3D artists who already have some experience with Blender, but if you are a motivated beginner, this course is great for you as well. The programs used in the course, ie Blender and fSpy, are free.The course includes two exercises that will get you familiar with the process. In the first exercise, a 3D model of a clock will be added to a wall in an image so that the clock forms a shadow on its surface. In the second exercise, 3D models of three coffee mugs will be added on top of a glass table in an image so that they will form both a shadow and a reflection on it. To do this they must be rendered in separate rendering layers and after that those layers will be added on top of each other using the node editor in the Compositor window.After the course, you can use the skill you have learned to add any 3D models on the surfaces of different kinds of images. This skill is often used, for example, when you want to fill an image of an empty apartment with realistic 3D models of furniture.
