Structures, space frames, lattice materials and articles of a great variety of shapes including interconnected struts and methods to make and use same. The structures have no nodes and are made from struts including plates that are interconnected in a 3D woven pattern. The advantages are lower cost, improved performance, and simpler manufacture of parts and assembly relative to traditional frames and articles. In an embodiment, the method of assembling parts is a 3D weaving algorithm/methodology. The 3D woven structures can be used in a great variety of different ways.

An assembly for integrating an elongate structural member is provided. The elongate structural member includes a first end portion, a second end portion, and an elongate mid-portion that extends between the first and the second end portions. The first end portion is within a first plane and the second end portion within a second plane, and the first and the second planes are offset and parallel to each other. The elongate mid-portion is sloped between the first and the second planes. each of the first and the second end portions defining therein a polygonal hole. Multiple elongate structural members may be used to assemble a lattice structure.

A system for generating a virtual reality environment includes a mocap suit having a plurality of sensors for generating at least one mocap suit output responsive to movement of an individual within the mocap suit within the virtual reality environment. At least one virtual reality player headset generates at least one virtual reality headset output responsive to actions of a player within the virtual reality environment. A virtual reality controller receives the at least one mocap suit output and the at least one virtual reality headset output and generates the virtual reality environment for display in the at least one virtual reality player headset. The virtual reality controller selectively generates an avatar associated with the mocap suit responsive to the at least one mocap suit output. The avatar being selectively inserted into the virtual reality world responsive to a first input and selectively removed from the virtual reality environment responsive to a second input.

A strut disclosed herein, where multiple such struts are configured to form a geodesic dome, where each strut includes multiple elongate rod members with multiple fastener-through holes defined on each of the elongate rod members. The opposing ends of each elongate rod member comprises a bolt hole, where each of the opposing ends of one elongate rod member is joined and fastened to other opposing ends of the other elongate rod members to define a hub, thereby defining a framework for the geodesic dome. Each fastener-through hole is configured to fasten a covering material of a predefined configuration over the framework defined by the elongate rod members, thereby forming the geodesic dome.

A building system comprising a plurality of tubes, a plurality of connection nodes comprising tubular sections for connection to the tubes, wherein the tubes are arranged to connect between the connection nodes to form a frame for a building, wherein at least one continuous cavity is formed through at least a portion of the nodes and tubes when the nodes and tubes are connected, the building system further comprising fluid tight seals between the tubes and connection nodes to enable fluid to flow through the at least one continuous cavity.

Geometrically tailored pyramidal lattice structures including inclined struts with I-shaped cross-sections can effectively support loads. For example, a truss system described herein can include a plurality of cells. Each of the cells can include a base plate. Additionally, each of the cells can include a plurality of struts. Each strut can include an I-shaped cross-section. Each strut can be attached at one end to the base plate. Each of the cells can also include a top plate. Each strut can be attached to the top plate at an opposite end. Additionally, each strut can extend at an inclined angle between the base plate and the top plate.

A system for controlling player movement within a fixed virtual reality play area includes a plurality of panels defining an X by Y virtual reality play area, a transport area associated with the X by Y virtual reality play area and a virtual reality system. The virtual reality system displays a virtual reality environment to players. The virtual reality system divides the X by Y virtual reality play area defined by the plurality of panels into a plurality of virtual reality environment play areas. Each of the plurality of virtual reality environment areas comprises a portion of the virtual reality play area. The virtual reality system associates a first virtual reality player group with a first virtual reality environment play area of the plurality of virtual reality environment play areas and associates a second virtual reality player group with a second virtual reality environment play area of the plurality of virtual reality environment play areas. The first and second virtual reality player groups include at least one player member. The virtual reality system determines if the second virtual reality environment play area has been vacated by the second virtual reality player group. If the second virtual reality player group has not vacated the second virtual reality environment play area, the virtual reality system prevents entry of the first virtual reality player group into the second virtual reality environment play area from the first virtual reality environment play area. If the second virtual reality player group has vacated the second virtual reality environment play area, the virtual reality system enables entry of the first virtual reality player group into the second virtual reality environment play area from the first virtual reality environment play area.

A method for preventing collisions in a physical environment for multiple players playing in a virtual reality environment comprises creating a plurality of virtual reality areas with respect to a physical environment. Each of the plurality of players are established as an active player in one of the plurality of virtual reality areas. Each of the plurality of players have an active player avatar mapped into a single virtual reality area of the plurality of virtual reality areas. Each of the plurality of players have a non-active player avatar mapped into each of the plurality of virtual reality areas where the user does not have an active player avatar. The active player avatars and the non-active player avatars are displayed in each of the plurality of virtual reality areas. A single avatar is present in each of the plurality of virtual reality areas for each of the plurality of players.

A system for generating a virtual reality environment includes a mocap suit having a plurality of sensors for generating at least one mocap suit output responsive to movement of an individual within the mocap suit within the virtual reality environment. At least one virtual reality player headset generates at least one virtual reality headset output responsive to actions of a player within the virtual reality environment. A virtual reality controller receives the at least one mocap suit output and the at least one virtual reality headset output and generates the virtual reality environment for display in the at least one virtual reality player headset. The virtual reality controller selectively generates an avatar associated with the mocap suit responsive to the at least one mocap suit output. The avatar being selectively inserted into the virtual reality world responsive to a first input and selectively removed from the virtual reality environment responsive to a second input.
