摘要： A method and technical equipment for encoding, where the method comprises at least receiving a video presentation frame, where the video presentation represents a three-dimensional data in the form of mesh data (810); separating from the mesh data information on vertices, wherein the information comprises at least connectivity data defining connections between vertices (820);
determining parameters relating to said connectivity data (830); encoding the parameters to a first bitstream as a video component (840); and storing the encoded first bitstream for transmission to a rendering apparatus (850). In addition to encoding, also decoding is disclosed.-

摘要： A hand-held turbine cleaning tool includes front and rear housings coupled to each other, an outlet at one end of the tool, and a top of the tool at an opposed end. The outlet is directed in a first direction away from the top. An inlet is disposed between the outlet and the top and is also directed in the first direction. A diverter valve at the inlet is moveable between on and off positions. The on position directs water flowing into the inlet from the inlet, up to the top in a second direction opposite the first direction, and then down to the outlet in the first direction. A turbine at the top has a turbine shaft that extends outside the tool. An abrasive member is connected to the turbine shaft and is configured to rotate when water flows from the inlet to the outlet.

摘要： A volumetric display capable of high-speed image presentation includes a resonance-type liquid lens having a focal length that is periodically adjusted using resonance of a liquid. An image projector projects an image toward a viewpoint position of a user via the resonance-type liquid lens. Further, the image projector projects an image toward the viewpoint position within a shorter time period than one-tenth of a variation cycle of the focal length. The image projector includes an LED and a DMD, for example.

摘要： An intelligent multi-visual camera system is disclosed that includes a multiple visual sensor array and a control system. The multiple visual sensor array includes multiple visual cameras spaced apart from each other. The control system also receives input from the multiple visual cameras, stores instructions that cause the processor to: initiate a registration system that projects images from the multiple visual cameras into a single three-dimensional volume and coordinate overlapping pixels of adjacent images amongst each other; detect one or more features of interest in the images from the multiple visual cameras; track one or more features of interest in one frame in one image from the multiple visual cameras into a subsequent frame in a subsequent image from the multiple visual cameras; deduplicate the projected images from the multiple visual cameras onto the ground plane; and communicate information regarding the features of interest that have been detected.

摘要： The present invention provides an information processing device and the like for a display device to represent, on the display device, a three-dimensional spatial representation that can be seen from a wide viewpoint direction. The display device includes a refraction means for refracting light and having a circle-shaped cross section; an arrangement support means for arranging and supporting a plurality of the refraction means in a convex shape with respect to a viewpoint side, and an image forming means for forming a formed-image on an opposite side surface to the viewpoint side with respect to the refraction means. The information processing device extracts an image data of a display element image displayed on each of the refraction means so as to look like three-dimensional spatial representation, from a three-dimensional spatial representation data for three-dimensional-spatially representing a display target, and generates a formed-image data for forming the formed-image in the opposite side to the viewpoint side of the predetermined refraction means so that the display element image can be displayed by a light having passed through the predetermined refraction means.

摘要： Disclosed are transparent energy relay waveguide systems for the superimposition of holographic opacity modulation states for holographic, light field, virtual, augmented and mixed reality applications. The light field system may comprise one or more energy waveguide relay systems with one or more energy modulation elements, each energy modulation element configured to modulate energy passing therethrough, whereby the energy passing therethrough may be directed according to 4D plenoptic functions or inverses thereof.

摘要： Methods and systems may provide for 3D volumetric displays. Such 3D volumetric displays may include a transparent enclosed volume holding a gas as a stationary gain medium. A scanning mirror may direct a light beam from a light source. A voxel projector may receive the light beam from the scanning mirror and may project an expanded beam into a volume of the stationary gain medium. Changes in the X and Y orientation between the light beam from the scanning mirror and the voxel projector results in relatively larger changes in the X and Y dimension of the expanded beam that is projected into the volume of the stationary gain medium to produce a 3D image.
