Useful Tools for Modeling

All the important modeling commands can be found on the Model toolbar. In addition, there are many other tools and features that you will find very useful while modeling.

Model Toolbar

You’ll find the Model toolbar at the far left of the screen. These commands are also available from the main menu.

 

Context Menus

Many modeling commands are available from context menus. The context menu appears when you Alt+right-click in the 3D views (Ctrl+Alt+right-click on Linux).

• If you click a selected object, the menu items apply to all selected objects. On Windows, you can also press the context-menu key (next to the right Ctrl key on some keyboards).

• If you click an unselected object, the menu items apply only to that object.

• When components are selected, you can right-click anywhere on the object that “owns” the selected components. The items on the context menu apply to the selected components.

• If you click over an empty area of a 3D view, the menu items apply to the view itself.

Views

Softimage includes several different views that can help you with your modeling tasks.

Explorer

The explorer displays the contents of your scene in a hierarchical structure. When modeling, it is particularly useful for seeing an object’s construction history, or geometry operator stack.

• For more information about the explorer, see The Explorer [Interface and Tools].

• For more information about the operator stack, see Operator Stack.

Object Viewer

The object viewer is a 3D view that displays only the selected scene elements. It is useful for isolating a specific object when modeling. For more information, see Object Views [Interface and Tools].

Schematic

The schematic view presents the scene as connected nodes in a graph so you can analyze the way a scene is constructed. It can display graphical links that show the modeling relationships between objects. For more information, see The Schematic View [Interface and Tools].

XSI Explorer

The XSI explorer is a view that combines an explorer tree for selecting objects and a viewing pane that can show other views, such as an object view or a schematic view. For more information, see The XSI Explorer [Interface and Tools].

Spreadsheet

The spreadsheet lets you execute queries and displays scene information about elements and their parameters in a grid. For more information, see The Spreadsheet [Interface and Tools].

Net View

Net View is an integrated Web browser within Softimage. You can use it to access sample content and resources available on the Internet. You can also create your own intranet for sharing resources across your workgroup.

• For information about using Net View, see Net View [Interface and Tools].

• For information about building your own intranet for use in Softimage, see Intranets for Net View [Customization].

Duplicating and Cloning

You can quickly build objects with similar parts by duplicating and cloning objects. A duplicate is simply a copy of another object, while a clone is a “linked” copy—you can modify all instances by modifying the original object. For more information, see Duplicating and Cloning Objects [Scene Elements].

Symmetry

To make a symmetrical copy of an object or hierarchy, use Edit > Duplicate Symmetry. For more information about duplicating, see Duplicating and Cloning Objects [Scene Elements].

There are also other symmetry features in Softimage:

• You can create symmetrical copies while drawing curves and chains (see Drawing Curves Symmetrically).

• You can maintain symmetry while manipulating points (see Manipulating Components Symmetrically).

• You can paint weight maps symmetrically (see Weight Maps and Symmetry [Scene Elements]).

• You can mirror envelope weights (see Mirroring Envelope Weights [Character Animation]).

• You can also apply a symmetry constraint for transformations (see Symmetry Constraints [Animation]).

• You can apply a symmetrize operator on a polygon mesh (see Symmetrizing Polygons [Polygon Modeling]).

Transformations

As you model objects, you will be moving them around; that is, translating, rotating, and scaling them and their components. For more information about transformations in general, see Transformations [Transformations].

Clipping Planes

When you are working on complex models, you sometimes want to focus on a specific part. For example, you may want to hide the backside of an object while you are moving points on the front.

To do this, you can set a camera’s clipping planes as described in Setting Clipping Planes [Lights and Cameras].

Rotoscopy

You can use rotoscopy to display background plates in the 3D views. This lets you use images as guides when modeling. For more information about rotoscopy, see Rotoscopy [Interface and Tools].

Geometry Approximation Parameters

The geometry approximation parameters control how the geometries of objects are approximated — the number of steps drawn per curve segment and so on.

By default, a new scene defines the geometric-approximation parameters for the Scene Root. This property is branch-propagated to all objects in the scene.

The Hardware Display parameters define the settings used for the OpenGL display in 3D views, while the Surface, Surface Trim, Polygon Mesh, and Displacement parameters define the settings used for rendering.

For more information about geometry approximation, see Viewing and Rendering Polygon Meshes [Polygon Modeling] and Geometry Approximation on NURBS [Surface and Curve Modeling].

 

Visibility, Display, and Selectability

Each object has visibility, display, and selectability parameters that can be set independently of the camera settings for the 3D views.

• The visibility parameters determine whether the object appears in the 3D views and when rendering.

• The display parameters control how the object appears as you select and modify it.

• The selectability parameter controls whether you can select or pick the object in a 3D view. You can always select objects in the Explorer no matter what the value of its selectability parameter.

These parameters are propagated through hierarchies; an object can either inherit its parent’s parameters or use its own local values. The global values for a scene are stored in the Scene_Root model. By changing these parameters, you can work faster by simplifying the tasks of viewing, selecting, and navigating around your scene.

For more information, see Setting Object Visibility Properties and Setting Display Options [Interface and Tools], and Defining Selectability [Scene Elements].

Display Options

Several display options are useful when modeling. For example:

• The headlight is a virtual light shining into the scene from the position of the camera. It is useful when you want to see the shadowed parts of scene objects.

• Wireframe opacity controls the intensity of the wireframe highlight in shaded views. It is useful for seeing the topology at the same time as the shading across edges.

Hierarchies

To organize the objects of a scene into a hierarchy, you parent one element to another—this lets you propagate properties down the hierarchy from the root element.

You can select an entire hierarchy at once in tree mode by right-clicking on any member of the hierarchy or select an individual branch by middle-clicking on the top node of the branch you want. For example, when you select an object in branch mode and translate it, its children are translated with it.

You can create hierarchies using the Parent button or by dragging and dropping nodes in the explorer. For more information about hierarchies in general, see Hierarchies [Scene Elements].

Layers

Layers are a useful tool for organizing your scene. You can divide your scene into layers and control the visibility, display, and selectability of all objects in a layer at once. For more information, see Scene Layers [Scene Elements].

Info Selection

Select an object and choose Edit > Info Selection or press Shift+Enter to get useful information about an object: name, type of geometry, number of components, number of triangles when tesselated for rendering, and so on.

Info Geometry

Selecting an object and choosing Edit > Info Geometry opens a page in Netview showing details about the object’s points and polygons (faces). If you select another object while the page is open, click Update to refresh the page with information about the newly selected object.
