Abstract: In one embodiment of the present invention, a position-based dynamics (PBD) framework provides realistic modeling and simulation for elastic rods. In particular, the twisting and bending physics of elastic rods is incorporated into the PBD framework. In operation, an elastic rod model generator represents the center line of an elastic rod as a polyline of points connected via edges. For each edge, the elastic rod model generator adds a ghost point to define the orientation of a material frame that encodes the twist of the edge. Subsequently, a PBD simulator solves for positions of both points and ghost points that, together, represent the evolving position and torsion of the elastic rod. Advantageously, the ghost points enable more realistic animation of deformable objects (e.g., curly hair) than conventional PBD frameworks. Further, unlike force based methods, elastic rod simulation in the PBD framework performs acceptably in environments where speed is critical.

Abstract: Techniques are disclosed for generating a consensus mesh to cover a received set of points. In one embodiment, a meshing application generates multiple meshes that cover the received point set by varying parameters of an interpolating meshing technique, such as the ball-pivoting technique, tangent-space Delaunay triangulation, and the like. Different values for the one or more parameters are used to generate each of the meshes. After generating the multiple meshes, the meshing application may sort triangles in the meshes based on the frequency in which the triangles appear in the meshes. The meshing application may then iteratively add next-best triangles which are also compatible with the current consensus mesh to the consensus mesh, with the next-best triangle being a most frequently occurring triangle which has not yet been added to the consensus mesh. Compatibility may be defined using various criteria, such as producing a manifold and orientable triangulation.

Abstract: A stroke parameterization engine within a rendering engine is configured to map a texture to the surface of a three-dimensional (3D) model along a stroke defined by an end-user of the rendering engine. The stroke parameterization engine converts the stroke to a polyline, then generates a geodesic trace by sliding a geodesic circle along the polyline and collecting points associated with the 3D model that fall within the geodesic circle. The stroke parameterization engine then parameterizes points associated with the polyline and the geodesic trace using UV coordinates associated with a texture map, thereby generating UV coordinates for each point within the polyline and geodesic trace. The stroke parameterization engine then projects the texture map onto the surface of the 3D model using the UV coordinates generated for the polyline and geodesic trace.

Abstract: In one embodiment of the present invention, a foldable beam generator produces a foldable beam polyline that approximates a three-dimensional (3D) space curve. The foldable beam generator optimizes the number and position of joints included in the foldable beam polyline to minimize differences between the foldable beam polyline and the 3D space curve while complying with one or more manufacturing constraints. Notably, the foldable beam generator designs each of the joints to act as a living hinge that closes to a fixed angle when heated and solidifies when cooled. By using the foldable beam polyline as a 3D digital model for manufacturing and subsequently applying heat to assemble the manufactured 3D object, defects and/or limitations of complex 3D objects typically associated with traditional manufacturing techniques may be reduced. In particular, support structures designed to buttress three-dimensional (3D) digital models during 3D printing may be minimized.
