Abstract: A method, apparatus, and computer program product provide the ability to construct a spiral toolpath for machining solid material. A polygon with a polygonal hole in an interior is obtained. A Voronoi diagram of a set of line segments is obtained and modified to provide a modified Voronoi diagram (VD) having a cycle with one or more trees growing out. For each of the trees, a wave model is defined for a wave that starts at time t=0 on leaves on a boundary of the hole and moves through the tree to hit leaves on a boundary of the polygon at time t=1. A polyline spiral curve toolpath is created by travelling around the wave as it moves towards the boundary of the polygon. A pocket is milled in a solid piece of material by following the polyline spiral curve toolpath.

Abstract: One embodiment of the invention sets forth a technique for identifying and avoiding impending collisions between moving objects in an animation. Paths traversed by the moving objects intersect at pre-determined intersection points. As a moving object approaches an intersection point, a collision avoidance module determines whether the object is on course to collide with another moving object also approaching the intersection point. If a collision is detected, then the collision avoidance module modifies the speed of the moving object to avoid the collision.

Abstract: A predictive electronic circuit design system, method, and apparatus provide the ability to design an electronic circuit. An electronic computer aided design (CAD) environment server computing device is connected to the Internet and includes a machine learning module program. The machine learning module program has a netlist analyzer program, a database, and a classifier and predictor program. The netlist analyzer program receives a circuit netlist for a designed circuit from a user, characterizes the circuit netlist, and sends characterization data to the database. Characterization data from multiple users for multiple designed circuits are stored in the database. The classifier and predictor program uses design goal data, the characterization data for multiple designed circuits, and simulation results, to calculate and produce predictions and proposals for the user to make design changes to the designed circuit in order to better meet or exceed design goals.

Abstract: A method, system, apparatus, article of manufacture, and computer readable storage medium provide the ability to automatically simulate a wind load. An analytical model is converted into a solid model. A wind flow on the solid model is simulated to determine pressures on structural elements of the solid model. The simulating is repeated until the pressures converge. The pressures are converted to loads on the structural elements. Load cases are generated with equivalent loads on the structural elements.

Abstract: A novel method designs and analyzes composite parts including optimal manufacturing strategies. The invention analyzes part design including curvatures and other surface topology to formulate an optimal strategy for material layup, number of plies, initial orientation angle, and towpath steering vectors. The method computes an optimum starting point for each fiber path and a stagger offset for each successive fiber path to as to eliminate or minimize gaps and overlaps between adjacent plies. Intermediate surfaces are generated by a polynomial discretization method which generates large computational time savings and enhances blending of adjacent zones to control surface smoothness. The method further calculates a variable steering path for the layer taking into account material parameters and limitations such that plies originating in the same location have a variable orientation angle and follow any reference curve generated by the method to maximize strength and minimize weight of the component.

Abstract: A system is discussed herein that that stretches or squashes the target body parts based on a relative size difference between a source and the target. The angular configuration of the source is matched exactly in the destination. The system allows a squash or stretch of a part to be determined from a goal determined by the source actor.

Abstract: In one embodiment of the present invention, a gesture recognition application enables interactive entry via a touch pad. In operation, the gesture recognition application partitions the touch pad into multiple zones. Upon detecting a gesture via the touch pad, the gesture recognition application determines whether the gesture is zone-specific. If the gesture is zone-specific, then the gesture recognition application determines the zone based on the location of the gesture and then selects an input group based on the zone and the type of gesture. If the gesture is zone-agnostic, then the gesture recognition application selects an input group based on the type of gesture, irrespective of the location of the gesture. Advantageously, by providing zone-specific gesture recognition, the gesture recognition application increases the usability of touch pads with form factors that limit the type of gestures that can be efficiently performed via the touch pad.

Abstract: A system for fabricating an object includes an extruder for one or more deposition materials having at least one nozzle and a movable support for the nozzle. The nozzle has a nozzle axis and is rotatably attached to the movable support via a connector that is actuatable relative to the movable support to change an angular orientation of the nozzle axis, thus varying an angle between the nozzle axis and a deposition surface. The system also includes a controller that can apply a correction factor calculated for a path of the nozzle when an acute angle is formed between the nozzle axis and the deposition surface, the correction factor for moving toward the acute angle being different from that when moving away from it. The correction factor removes differences in thickness of the deposited material caused by variations in the angle formed between the nozzle axis and the deposition surface.

Abstract: One embodiment of the invention disclosed herein provides techniques for voxelizing a mesh representation associated with a three-dimensional model to generate a volumetric model. A model filling engine associated with a voxelization system identifies a first voxel included in a voxel grid array that intersects with the mesh representation. The model filling engine selects a second voxel at an exterior boundary of the voxel grid array that is not identified as a boundary voxel. The model filling engine marks the second voxel as an exterior voxel. The model filling engine marks all unmarked voxels that are adjacent to the second voxel as exterior voxels. The model filling engine marks all remaining voxels as interior voxels. A model finishing engine associated with the voxelization system generates a volumetric model based at least in part on the first voxel.
