blender 灯光和渲染基础(第四章).doc

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 important 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 to 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 use—an outdoor scene, an indoor scene, and a hybrid scene that incorporates elements that are found both inside as well as outside. All these files can be downloaded from /lighting-and-rendering/. 在我们开始前，需要一个场景文件。这里为我们提供了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/lighting-and-rendering/. The 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 product 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 /lighting-and- rendering/ and select exterior.blend. 要下载本教程的文件，请访问 /lighting-and- rendering/ and select exterior.blend. Blender render settings In computer graphics, a two-dimensional 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 settings Blender provides us, we can set frame rat
