In various embodiments of the present invention, a blending engine blends multiple surfaces included in a three-dimensional (3D) model of an object. First, the blending engine trims off portions of the surfaces that are targeted for blending at trimming curves to generate trimmed surfaces. The blending engine then constructs a single parametric blending surface via a unified parametrization for the trimming curves. Notably, to achieve the unified parametrization, the blending engine performs one or more spherical parametrization operations that generate parametrized curves based on the trimming curves and a fundamental sphere. After constructing the parametric blending surface based on the parametrized curves, the blending engine joins the parametric blending surface to the trimmed surfaces to produce a final, smooth intersection between the surfaces. Advantageously, because the blending engine creates a single parametric blending surface, the blending engine can blend arbitrary pipe surfaces and is compatible with computer-aided design modeling subsystems.

A method and system provide the ability to modify a three-dimensional (3D) model in a shape editing system. The 3D model is obtained and faces of the model are selected as features (S). A subset (S) of the model that are fixed are selected. Shape modification operations to be performed are prescribed. A deformation lattice is constructed by setting up a lattice structure with control points. Parametric space (u,v,w) is defined in terms of vertices of the lattice structure. Euclidean space (x,y,z) of the 3D model is mapped to the parametric space (u,v,w). The deformation lattice is evaluated by selecting control points, and either affine transformations are applied directly to the selected control points, or the deformation lattice is deformed based on a discrete fitting problem. The evaluated deformed model is then output.

In one embodiment, a device generator automatically generates a circuit, firmware, and assembly instructions for a programmed electronic device based on behaviors that are specified via mappings between triggers and actions. In operation, the device generator generates a circuit based on the mappings. The circuit specifies instances of electronic components and interconnections between the instances. Subsequently, the device generator generates firmware based on code fragments associated with the triggers and actions included in the mappings that specify the high-level behavior. In addition the device generator generates assembly instructions based on the interconnections between the instances. Advantageously, the device generator provides an automated, intuitive design process for programmed electronic devices that does not rely on the designers possessing any significant technical expertise. By contrast, conventional design processes for programmed electronic devices typically only automate certain steps of the design process, require specialized knowledge, and/or are limited in applicability.

A method, system, and apparatus provide the ability to globally register point cloud scans. A first and a second three-dimensional (3D) point cloud are acquired. The point clouds have a subset of points in common and there is no prior knowledge on an alignment between the point clouds. Particular points that are likely to be identified in the other point cloud are detected. Information about a normal of each of the detected particular points is retrieved. A descriptor (that only describes 3D information) is built on each of the detected particular points. Matching pairs of descriptors are determined. Rigid transformation hypotheses are estimated (based on the matching pairs) and represent a transformation. The hypotheses are accumulated into a fitted space, selected based on density, and validated based on a scoring. One of the hypotheses is then selected as a registration.

A system and method are disclosed for manipulating objects within a virtual environment using a software widget. The software widget includes one or more controls for performing surface constrained manipulation operations. A graphical representation of the software widget is superimposed over the object and enables a user to use simple mouse operations to perform the various manipulation operations. The position operation determines an intersection point between the mouse cursor and a surface of a different object and moves the object to the intersection point. The scale operation adjusts the size of the object. The rotate operation adjusts the rotation of the object around a normal vector on the surface of the different object. The twist operation deforms the object along a local z-axis. The orientation operation adjusts the orientation of the object with respect to the normal vector.

In one embodiment, a model generator generates a new model for a behavior of a system based on an existing, authoritative model. First, a mapping generator generates a mapping model that maps authoritative values obtained via the authoritative model to measured values that represent the behavior of the system. Subsequently, the model generator creates the new model based on the authoritative model and the mapping model. In this fashion, the mapping model indirectly transforms the authoritative model to the new model based on the measured values. Advantageously, the authoritative model enables the model generator to increase a rate of accuracy improvement experienced while developing the new model compared to a rate of accuracy improvement that would be experienced were the new model to be generated based on conventional modeling techniques. In particular, for a given sampling budget, the model generator improves the accuracy of the new model.
