Houdini ——10Welcome to houdini (欢迎进入houdini)Use Edit > Open help browser at startup to control whether this page appears when Houdini starts up.编辑菜单> Open help browser at startup （启动帮助浏览器）是否被勾选决定了帮助浏览器是否会随houdini 的启动而运行User interface intro(用户界面介绍)A quick introduction to Houdini and its user interface.快速介绍houdini 软件及其用户界面 Holding down Spaceactivates the View tool.按住空格键激活相机工具While you hold down the space bar, the mouse buttons control the view, and hotkeys change to view-specific functions. 当你按住空格键的同时，鼠标按键就可以对视图进行操作，快捷键变成了具体的视图操作功能You can select the View tool in the toolbox (to the left of the 3D view) for continuous viewing without having to hold down Space 你也可以在3D 视图的左侧工具盒中选择相机工具去继续视图操作。

如果是在工具栏中选择了相机工具那么在操作视图时是不需要再按住空格键了.Viewing the scene 观察视图Space is the “view key” in Houdini. 在houdini 当中空格键相当于查看键Move the mouse over the 3D view. 在3D 视图中移动鼠标空格键+鼠标中键 平移视图空格键+鼠标左键 旋转视图空格键+鼠标右键 /滚轮 缩放视图按住空格键同时点鼠标。

或Use the viewport menus to set options related to the 3D view. Move the mouse over a viewport and press Space+B to switch between single and multi-viewport layouts.通过设置选项将视图菜单与3D 视图联系起来。

将鼠标移动到视图窗口上然后按 空格键+b 键 可进行单视图与多视图的切换Press D in the viewer to bring up a window of display options.在当前视图中按d 键会弹出-显示选项的窗口（再次按d 键关闭显示选项窗口）The display toolbar down the right side of the 3D view has controls for showing and hiding various components and features in the view.在显示工具条右侧有可以打钩的选项用来控制显示和隐藏视图中的一些组员物体及专有选项The floating menus in each viewport control viewing source, direction, and options for each viewport. 在每个窗口中都为当前窗口设置了浮动菜单以控制当前窗口的观察方向，显示类型及其它选型视口布局显示所有物体其他物体鬼影显示隐藏其它物体显示方式视图选项相机/灯光视角观察视图Use the viewport layout menu in the viewer toolbar to choose the layout. The icon changes to show the selected layout. 在视图窗口中使用视口布局菜单选择窗口布局。

不同的图标显示了出当前要选择的窗口布局Shading modes(阴影显示方式)The shading mode controls how Houdini draws objects and geometry in the viewer.在houdini窗口中物体和几何体以怎样的模式显示You can also set different display profiles for selected, unselected, and other types of geometry. 你同样可以为已选物体、未选物体和其它类型的几何体设置不同的显示方式Move the mouse over the view and press D to open the display options window, then use the options on the Guides and Markers tab. 把鼠标移动到视图窗口并按d键开启显示选项窗口，然后就可以使用面板中的选项进行操作Press W to quickly switch between wireframe and shaded mode.w键可以快速切换线框模式和实体模式Click the shading menu on the toolbar across the top of the viewer to choose a shading mode.在工具条上单击阴影菜单，从下拉菜单中选择显示方式Using the shelf(工具架的使用)The shelf across the top of the main window contains commonly used tools and commands.工具架上设置了主菜单中普遍常用的工具和命令Click the Box icon on the shelf, then move the cursor over the 3D view.在工具架上单击立方体图标，然后将光标移动到视图中Click to place the box in the scene, or press Enter to place it at the origin.立方体光标在场景中任意地方单击，物体即被创建于鼠标单击位置或者按下回车键，则物体被创建于世界坐标中心Object nodes and surface nodes(物体节点和曲面节点)Geometry objects consist of a Geometry container object, and surface nodes inside.几何物体是由几何形体外壳和内部曲面节点共同构成If you double-click the box object in the network editor, you will go inside the Geometry container t o the “Geometry” level 在网络编辑窗口中如果你在立方体图标上双击鼠标，你将进入到几何体外壳中的“几何体”层级where surface nodes define the shape of the object by creating and manipulating curves and surfaces.曲面节点为创建和控制曲线和曲面而确定了物体形状Click the Back button to go back to the Scene level.单击返回按钮回到场景级别Selecting objects(选择物体)You can select whole objects with the object selection mode and the Select tool.你可以在物体选择模式下或者利用选择工具选择整个物体Click the Object selection mode icon at the top of the toolbox (on the left side of the 3D view).在工具盒上单击物体选择模式图标（3D视图的左边）Click the Select tool. This tool lets you select objects in the 3D view.单击选择工具，这是个能让你在三维视图中选择物体的工具Click the box object to select it if it’s not already selected.如果你还没有选择物体在立方体上单击物体即被选择Click in empty space to de-select the box object. 在空白的地方单击鼠标取消选择Handles(手柄)Handles let you directly manipulate objects and operations in the view.手柄是让你在视图中快速直观的操作和控制物体Select the box object and then click the Move tool 选择立方体然后单击移动工具Drag the arrows to move the box along the X, Y, or Z axes. 拖拽箭头可以单独沿着X.Y或者Z轴移动立方体Drag the square in the center to move the box along the construction plane.拖拽坐标轴中间的正方形,立方体会沿着构造平面移动（XY.XZ.YZ.）Parenting objects(物体父子关系)Parents apply their transformations to their children.子物体继承其父物体的变换属性Normally an object may “jump” position as it assumes its parent’s transforms.假设变换父物体，通常子物体的位置会发生“跳动”(对齐到父物体中心)To prevent this, when you select the child object, turn on Keep position when parenting in the parameter editor before you parent it. 为预防这种事情发生，当你选择子物体时，在未设置父子关系前开启“当设置父子关系时保持相对位置”To parent one object to another…为一个物体与另一个物体设置父子关系1.Select the child object.选择子物体2.Click Parent in the Modify shelf. 在修改工具架上单击父子连接工具3.Click the parent.单击父物体（按回车父子关系被创建）选择子物体在修改工具架上选择父子关系图标，在场景空白处单击然后回车则取消父子关系Connect the parent node’s output to the child node’s input in the network editor.或者，在网络编辑窗口中把父物体的输出节点链接到子物体的输入节点上Selection mode(选择模式)The selection mode controls whether you are working on objects or components, and which type of components选择模式是控制你是在物体模式下操作还是在组分级别下操作，并且可以转化不同的组员级别（点，线，面，体）In object mode, you select objects, such as geometry containers, lights, cameras, and characters.你可以在物体模式下选择物体，例如几何体、灯光、相机及角色In component mode, you select geometry components, such as points, faces, edges, and vertices.你可以在组分模式下选择几何体的组分级别，例如点、面、边及顶点Click the Object mode icon for object selection mode. 当选择物体时单击物体模式图标In object mode, the Select tool is a black arrow. 在物体选择模式下，选择工具是黑色箭头Click the Component mode icon below the object mode icon for component selection mode.单击物体选择模式图标下面的组分选择模式图标进入物体组员选择模式The icon on the component selection mode button changes to show the current component type.组分选择模式按钮图标的改变显示了当先组员类型In component mode, the Select tool is a white arrow. This is just another way to tell which mode you're in.在组分选择模式下，选择工具为白色箭头，这仅仅是显示了你当前处于哪种编辑模式下的一种方式而已You can also press F8 to switch between object and component mode, or use the 1-4 keys to switch between selection types.你可以按F8 键切换物体模式与组分模式，或者使用1-4个数字键切换选择类型Component type（组员类型）In component selection mode, you can choose which type of component to select.在组分选择模式下，你可以选择哪种组员类型被选择Points lets you select the points at the corners of polygons, or the CVs of NURBS curves or surfaces.点：能让你选择多边形转角上的点或者NURBS曲线及曲面上的CV点Edges lets you the polygonal edges between points.边：能让你选择多边形物体两个点之间的边Primitives lets you select polygonal faces, NURBS surfaces, and metaballs.图元：能让你选择多边形的面，NUEBS的面及变形球Vertices lets you select UVs and individual polygonal vertices. When polygons are fused together, one point can represent several vertices.顶点：能让你选择UV点及多边形的特定顶点，当多个多边形物体结合为一个物体时其一个点就代表若干个顶点Right-click the selection mode button (below the Object selection mode button) and choose Primitives.（在物体选择模式下面）的选择模式按钮上单击鼠标右键--选择--图元类型Selecting components(选择组员)You can select components of an object (such as points, faces, and edges) with the component selection mode and the Select tool.你可以在组分级别下用选择工具选择组员物体例如点，面，边Note that in object mode, the select arrow is black, and in component mode it’s white. This is just another way of indicating which mode you're in.既然在物体选择模式，那么选择工具为黑色箭头，在组分级别下为白色箭头。
