摘要： Systems, methods, and computer storage mediums are provided for blending custom terrain patches onto a terrain of a virtual three-dimensional environment. A method includes accessing terrain data that describes a mesh representing the surface of the terrain of the three-dimensional environment. The mesh is constructed of primitives that are defined by a terrain altitude at each vertex. A surface grid is determined from the primitives such that each point in the surface grid includes the terrain altitude where the point falls on the mesh. Custom terrain data is also accessed that includes a custom grid of terrain altitudes. A patch grid is determined from the custom grid such that each point in the patch grid includes a terrain altitude derived from the custom grid. The patch and surface grids are blended such that each terrain altitude in the patch grid modifies its corresponding terrain altitude in the surface grid.

摘要： A filter media and methods are provided. The media is stretchable and exhibits a high degree of elongation which thereby extends its surface area during pleating. By extending surface area of media during pleating, the initial differential pressure is lowered as the area of media is stretched while keeping the same efficiency range with a compressed thickness of media on the affected area.

摘要： Disclosed are systems and methods for processing events in an event stream using a map-update application. The events may be embodied as a key-attribute pair. An event is processed by one or more instances implementing either a map or an update function. A map function receives an input event from the event stream and publishes one or more events to the event stream. An update function receives an event and updates a corresponding slate and publishes zero or more events. Systems and methods are also disclosed herein for implementing a map-update application in a multithreaded architecture and for handling overloading of a particular thread or node. Systems and methods for providing access to slates updated according to update operations are also disclosed.

摘要： Various embodiments of a system and methods for generating a manifold surface of an object from a set of 3D curves which define the shape of the object are described. The set of 3D curves may be directly tessellated in the 3D domain to form a manifold surface with boundary. The tessellation may be a Delaunay tetrahedralization which represents the set of 3D curves. The surface of the tetrahedralization may contain a set of possible manifold surface solutions. A dual complex form of the tetrahedralization may be generated to reduce the number of possible manifold surface solutions. Surface patches may be generated from the dual complex form, dependent on a set of metrics that may further reduce the number of possible manifold surface solutions. Compatible surface patches may be combined to form a set of possible manifold surface solutions which may be displayed to a user.

摘要： Syntheses of a new blue EC monomer (ProDOT-MePro), and a new red EC monomer (ProDOP-Et2) are described. Two additional new types of EC monomers based on 3,4-alkylenedioxythiophene include fluorinated EC monomers and an EC monomer including silicon. EC polymer devices having more than one different color EC polymer to enable additional colors to be provided using subtractive color mixing are also described, as well as EC polymer devices incorporating a logo, image, or text, are generally obscured when the device is colored, but become visible when the device is not colored. Also described are EC polymer devices that include a cathodic EC polymer layer, a gel electrolyte, a counter electrode, and a reference electrode. Working prototypes of such devices exhibit significant increases in the speed of transition of the EC device from a colored state to a transparent state.
