Methods, systems, and apparatus, including medium-encoded computer program products, for volumetric kernel representation of three dimensional models include: modeling a three dimensional object using a volumetric representation including fields that determine volumetric properties, each of the fields being parameterized by an input and output tensor structure, and at least one of the fields mapping tensor output of a first of the fields to tensor input of a second of the fields to provide a unified framework for geometry manipulation and composition that encompasses both discrete and continuous representations of materials in the three dimensional space; evaluating the fields including using coverage values that determine compositing behavior to generate output data corresponding to the volumetric properties; and providing the output data for the three dimensional object having physical characteristics that vary from point to point within a volume of the three dimensional object in accordance with the volumetric properties.

Volumetric kernel representation of three dimensional models

A method, apparatus, system, and computer-readable storage device is configured to perform three-dimensional (3D) modeling. A modeling tool is activated in a 3D modeling application executing on a multi-touch device. An input touch event and input gesture for creating a new 3D geometric form is received. Dynamically, in real-time as the input gesture is received, the new 3D geometric form is created and displayed. The shape of the new 3D geometric form corresponds to the input gesture.

Dynamic creation and modeling of solid models

A modeling tool is activated in a 3D modeling application executing on a multi-touch device. A visual representation of a grid system tool is displayed in an active modeling plane and has three separate regions that determine the type of operation to be performed. An existing 3D form is displayed on the tool. A starting touch event of a gesture is received over the existing 3D form within one of the regions. As the gesture is received in the computer, the 3D form may be dynamically extended by adding 3D geometry to the 3D form (thereby adding faces to the 3D form). Alternatively, the 3D form may be scaled (i.e., if the starting touch event occurs over a visual scale grip. Alternatively, if the gesture consists of two taps, a bridge may be created joining the two tapped locations.

Gestures and tools for creating and editing solid models

A method, apparatus, article of manufacture, and computer readable storage medium provides the ability to perform a three-dimensional (3D) modeling operation. A modeling tool is activated in a 3D modeling application. A visual representation (having three separate regions) of a grid system tool is displayed on a digital modeling canvas of the 3D modeling application. The grid system controls whether a gesture is captured as a modeling operation or a navigation operation. A starting touch event (of the gesture) is received in/on one of the three separate regions. The region where the starting touch event is received determines the operation that is to be performed/selected. The operation may be a 3D geometry creation operation, a restroking operation, or a navigation operation.

Three dimensional contriver tool for modeling with multi-touch devices

A method, apparatus, system, article of manufacture, and computer readable storage device provides the ability to manipulate an object in a three-dimensional (3D) modeling system. A first object is displayed and then selected in the 3D modeling system. In response to the selecting, a transform manipulator is displayed displaying coincident with the first object. The transform manipulator includes a two-dimensional (2D) control plane object and grips located on the 2D control plane object. One of the grips is activated and used to manipulate the first object.
