1、翻译Outdoor Lighting: Setting Up Our Scene室外光源：Lighting techniques are highly dependent on the location of the scene at hand. The approaches to lighting an outdoor scene are radically different from the techniques used to light an indoor scene. Knowing these differences and when to use each is importa
2、nt when aiming for a believable result. We will take a look at:灯光技术高度取决于在场景的位置。室外灯光和室内灯光的处理技术是完全不同的。知道这些不同是很重要的对于我们创建一个真实可信的渲染结果。接下来我们将看看以下内容： Establishing a workflow确定工作流程 Things to consider when lighting a scene照亮一个场景应该考虑的事情 Adding and editing lights in Blender在 Blender 添加或编辑灯光 How to use layers t
3、o increase the quality of our render怎么使用层来提高我们的渲染质量 What habits are good when lighting and why那些习惯是好的和为什么是好的Getting the right flies 获取文件Before we get started, we need a scene to work with. There are three scenes provided for our usean outdoor scene, an indoor scene, and a hybrid scene that incorpora
4、tes elements that are found both inside as well as outside. All these files can be downloaded from http:/ 3 个场景文件-一个室外场景，一个室内场景，和一个包含室内和室外的混合场景。所有的文件可以从这里下载http:/ file we are going to use for this scene is called exterior.blend. This scene contains a tricycle, which we will light as if it were a pro
5、duct being promoted for a company.我们将要使用的场景文件叫 exterior.blend。这个场景包含一个三轮车，我们将假设它是一个公司的宣传产品来设置照明布局。To download the files for this tutorial, visit http:/ rendering/ and select exterior.blend.要下载本教程的文件，请访问 http:/ rendering/ and select exterior.blend.Blender render settingsIn computer graphics, a two-di
6、mensional image is created from three-dimensional data through a computational process known as rendering. Its important to understand how to customize Blenders internal renderer settings to produce a final result thats optimized for our project, be it a single image or a full-length film. With the
7、settings Blender provides us, we can set frame rates for animation, image quality, image resolution, and many other essential parts needed to produce that optimized final result. Because we are going to use the same render settings for all projects in this book, we are going to take a look at how to
8、 set those values now.在电脑图形中由 3D 图像通过计算得到 2D 图像的过程叫渲染。它是很重要的对于我们理解如何设置 Blender 内部渲染器来优化我们的项目产生最终的渲染结果，一个单一的图像或完整的影片。在 Blender 里，我们能够设置动画帧速率，图像质量，图像分辨率，和其它优化我们的产品最终结果必不可少的设置。因为我们将在本书中所有项目使用一样的设置，让我们看看怎么设置这些值。The Scene menu 场景菜单We can access these render settings through the Scene menu. Here, we can a
9、djust a myriad of settings. For the sake of these projects, we are only going to be concerned with:我们可以通过场景菜单访问这些渲染设置，在这里有大量的参数设置，但我们对于我们的这些项目，我们仅仅需要考虑的是： Which window Blender will render our image inBlender 将在那个窗口渲染图像 How render layers are set up (we will discuss this in more detail later on)怎么设置渲染
10、层（我们将稍后讨论更多的细节） Image dimensions图像大小 Output location and file type输出路径和文件类型Render settings 渲染设置The first settings we see when we look at the Scene menu are the Render settings. Here, we can tell Blender to render the current frame or an animation using the render buttons.首先让我们来看看场景菜单的 Render 设置。在这里我
11、们可以通过使用按钮告诉 Blender 渲染当前帧或一个动画。We can also choose what type of window we want Blender to render our image in using the Display options.我们可以在 Display 选项选择 Blender 渲染一个图像时，使用哪一种窗口类型。The fist option (and the one chosen by default) is Full Screen. This renders our image in a window that overlaps the thr
12、ee-dimensional window in our scene. To restore the three-dimensional view, select the Back to Previous button at the top of the window.第一个选项是全屏（默认） 。渲染图像时将覆盖我们的 3d 窗口。要返回到 3D 窗口视图，选择顶部的 Back to Previous 按钮.The next option is the Image Editor that Blender uses both for rendering as well as UV editing
13、, which we will cover later. This is especially useful when using the Compositor, allowing us to see our result alongside our composite node setup. By default, Blender replaces the three-dimensional window with the Image Editor.接下来的是 Image Editor,可以用为渲染窗口还可以用 UV 编辑，我们稍后将讲到。这个选项在我们合成时候非常有用，允许你边查看渲染结果
14、边编辑节点。默认的渲染图像将覆盖住 3D 视图窗口。The last option is the option that Blender has used, by default, since day oneNew Window. This means that Blender will render the image in a newly created window, separate from the rest of the programs interface.最后一个选项是 New Window。它在 Blender 渲染图像时将创建一个独立于软件界面的新窗口。For the sa
15、ke of these projects, were going to keep this setting at the default settingFull Screen.对于这些项目，我们将保持默认的设置- Full Screen。Dimensions settings 大小设置These are some of the most important settings that we can set when dealing with optimizing our project output. We can set the image size, frame rate, frame range, and aspect ratio of our render. Luckily for us, Blender provides us with preset render settings, common in the film industry:这里对于项目有一些重要的设置。我们可以设置图像尺寸，帧速率,和我们渲染的方向率。幸运的是，Blender 为我们提供了电影工业常用的渲染设置： HDTV 1080P HDTV 720P TV NTSC TV PAL TV PAL 16:9Because we want to
