Users define object control rigs that can be used to perform specific object manipulation tasks for the user when manipulating objects in a scene. Different rigs can be constructed for the same set of animation objects to perform different tasks. A rig is modeless in that a rig may include an arbitrary user-selected mixture of object control elements that are typically used in different modes and scopes of manipulation. When a user selects a rig, all of the visual representations of the object control elements specified for that rig are enabled to be displayed proximal the object(s) with which the control elements are associated. No additional selection of object parts is necessarily required to determine which control elements are associated with the object(s). The user may manipulate the object(s) using a displayed visual representation of an object control element.

Systems and methods for creating and using modeless animation manipulation rigs

Systems and methods for custom designing modeless rigs or sets of object control elements that can be used when manipulating one or more objects.

A system and method enables animators to efficiently pose character models' feet. An initial foot model position is received. The initial foot model position specifies a foot model contact point. One or more foot roll parameters are specified that change the relative angle between at least a portion of the foot model and an initial orientation of an alignment plane. Foot roll parameters specify the rotation of the foot model around foot model contact points. Foot roll parameters can include heel roll, ball roll, and toe roll, which specify the rotation of the foot model around contact points on the heel, ball, and toe, respectively, of a foot model. To maintain the position of the foot model contact point, the foot model position is adjusted based on the foot roll parameter. The repositioned foot model is realigned with alignment plane, which restores contact at the foot model contact point.

Techniques for customizing draw styles of widgets to better accommodate a user's direct manipulation needs. A user can customize various attributes of a widget and its manipulators to suit the user's needs. The customizations are stored as a style. The stored style can subsequently be applied to the widget to control the appearance and behavior of the widget. Stored styles may be applied to other widgets and can also be shared between users.

Customizing widget draw styles

A method for a computer system includes displaying a toolbar region with user selectable icons on a display, positioning a cursor on the display over the toolbar region, and receiving a first command from the user while the cursor is positioned over the toolbar region, wherein the first command from the user comprises pressing and holding of a button on a user input device, displaying additional user selectable icons on the display in response to the first command, positioning the cursor on the display over one user selectable icon, and receiving a second command from the user while the cursor is positioned on the one user selectable icon, wherein the second command from the user comprises releasing the button on the user input device, wherein the one user icon and the user selectable icons are then displayed in the toolbar region in response to the second command.

A graphical user interface for a computer system includes a display portion configured to display a representation of a first three-dimensional object, wherein the first three-dimensional object has an associated first volume, and a control icon associated with the first three-dimensional object, wherein the control icon is configured to allow a user to specify a bend amount to the first three-dimensional object in a first dimension, wherein the display portion is also configured to display a representation of a bent first three-dimensional object, wherein the bent first three-dimensional object comprises the first three-dimensional object that is bent lengthwise in response to the bend amount, and that may have an adjusted thickness in response to the bend amount.

A graphical user interface for a computer system includes a display portion configured to display a representation of a first three-dimensional object and a second three-dimensional object, wherein the first three-dimensional object has an associated first volume, and wherein the second three-dimensional object has an associated second volume, and a control icon associated with the first three-dimensional object, wherein a user can specify a modification to the first three-dimensional object in a first dimension via the control icon, wherein the display portion is also configured to display a representation of a modified first three-dimensional object, wherein the modified first three-dimensional object comprises the first three-dimensional object that is modified in the first dimension in response to the modification and that is modified in a second dimension in response to the modification and to a volume preservation value.
