Abstract: Methods and apparatus for deactivating internal constraint curves when inflating an N-Sided patch. Given a patch representation, the methods simplify the construction of 3D models from 2D sketches. At least some interior constraint curves may be deactivated when inflating an N-sided patch generated from a 2D sketch, or when performing other surface deformation tasks. An inactive constraint is a passive curve that stays on the surface and that gets modified along with the surface when the surface is inflated, but that does not affect the surface itself. By changing parameters stored at the active constraints, embodiments may modify the surface and turn the inactive constraints from flat 2D curves into 3D space curves. The inactive constraints can be activated at any time when their 3D shape meets the user's expectations.

Abstract: In using an application's drawing feature, users typically use connecting lines between graphical shapes to depict a relationship between the shapes. Drawing connecting lines between two or more graphical shapes within an application can be a time consuming, manual task. An application that automatically generates connecting lines between shapes, based on spatial relationships among the shapes, can reduce the amount of time for drawing a diagram. Functionality can be implemented to generate connecting lines between 1:n shapes based on proximity among the shapes and/or contact between shapes. Automatically generating connecting lines among shapes based on spatial relationships among the shapes allows generating of the connecting lines based on manipulation of shapes, which typically have a larger surface area than a line. Manipulating a larger surface area can be easier than manipulating a line.

Abstract: One embodiment of the present invention sets forth a technique for converting dashed strokes into quadratic Bèzier segment sequences. Path rendering with stroking and dashing may be accelerated when a graphics processing unit or other processor is configured to subdivide quadratic Bèzier segments based on the remaining distance for a current dash pattern element and the arc length of the current quadratic Bèzier path segment to generate “on” dash pattern segments. Each “on” dash pattern segment is then bounded by a conservative geometric hull. A point containment technique is then used to identify pixels within each conservative geometric hull that are within half of the stroke width of any point along a path to be stroked.

Abstract: A method and system for representing multiple road properties with a single multi-dimensional parametric spline curve is disclosed. A B-Spline is generated to represent a first road dimension. The B-Spline is written mathematically in vector format. One or more road dimensions to be added to the B-Spline are selected.

The new B-Spline vector is then stored in a data storage unit for use by systems, such as Advanced Driver Assistance Systems.

Abstract: This disclosure describes a multi-stage tessellation technique for tessellating a curve during graphics rendering. In particular, a first tessellation stage tessellates the curve into a first set of line segments that each represents a portion of the curve. A second tessellation stage further tessellates the portion of the curve represented by each of the line segments of the first set into additional line segments that more finely represent the shape of the curve. In this manner, each portion of the curve that was represented by only one line segment after the first tessellation stage is represented by more than one line segment after the second tessellation stage. In some instances, more than two tessellation stages may be performed to tessellate the curve.

Abstract: A system and method for approximating parametric curves may subdivide curves using a minimum number of subdivisions while meeting a given error tolerance. The method may include determining a subdivision point such that the maximum chord error on one side of the point is equal to the maximum chord error on the other side of the point, the chord error being the distance between the curve and a linear approximation thereof. These techniques may be applied recursively to sub-portions defined by the subdivision point if the maximum error is greater than a pre-determined error tolerance. The pre-determined error tolerance may be a default tolerance, or may be application-specific or user-configurable, in various embodiments. By subdividing a curve into fewer segments than conventional methods, the system and methods described herein may allow an alternate representation of the curve to be generated that includes less data than one generated using conventional methods.

A large data segment is adaptively decimated to a smaller size automatically so that a lower resolution version of the data segment will be loaded into a fixed-size small buffer in hardware working space for further data editing. The decimation and loading process will be repeated until the user finds the desired data-section of interest.

Abstract: A curve drawing system is described herein that rasterizes arc splines in the GPU of a computer for cubic Bezier drawing of strokes and thin features. The curve drawing system first converts a cubic Bezier representation into an arc spline representation. Then the curve drawing system uses a similar approach to Loop/Blinn modified to cause the pixel shader to perform a point-in-circular-arc test instead of a point-in-Bezier test. Calculating arc radius is a much simpler operation than the alternatives and can be easily and efficiently performed by the pixel shader. Since the stroke of an arc spline is also an arc spline, the drawing system provides a resolution-independent representation of strokes. Thus, the curve drawing system allows several previously difficult graphical features to be efficiently drawn by readily available legacy hardware and used in software programs that are designed to run on a wide variety of hardware.

Abstract: Methods and apparatus for decomposing an N-sided patch into multiple patches. A single patch may be decomposed into multiple, disjoint, and possibly abutting patches. An internal constraint curve may be selected, and a new patch with the constraint curve as the boundary may be generated. If the constraint curve is closed, it is turned into a hole in the original patch. If the constraint curve is not closed, the system closes the curve. The 3D position, surface normal, and possibly other information such as an up direction required for every point along the boundary of the new patch may be taken from the original patch surface. The new patch(es) may be edited independent of the original patch and may be further decomposed into more patches.

Abstract: A system of curve generation takes a sequence of control points and constraint codes for each control point, and outputs a curve in which each of the constraints is satisfied. The set of constraints is chosen from the tangent angle, curvature, first derivative of curvature, and second derivative of curvature.

At each control point, a choice of G2 curvature continuity (tangent angle and curvature) or G4 curvature continuity (tangent angle and curvature plus first and second derivatives of curvature are continuous) is input. The desired curve is expressed as the solution to the chosen set of constraints.

Mass points may be added to or removed from the model by adaptive resampling, and the mass redistributed accordingly.

Abstract: Complex labyrinth curves are interactively generated by an iterative process that spatially modulates curve evolution by an image or other function defined on the evolution space. After curves and evolution parameters are initialized [100], the iterative process resamples the curves [104], and spatially modulates the curves according to the evolution parameters [106]. The spatial modulation includes computing sample point displacements by calculating distances between each of the sample points and neighboring points using a surface distance metric that estimates a geodesic distance metric in a two-dimensional non-Euclidean evolution space. The evolved labyrinth curves are may be processed [110] for use in various applications. The evolved curves can also be triangulated and projected to a plane to create patterns for manufacturing developable surfaces.
