System for implementing remote control interaction in virtual three-dimensional scene

InactiveCN101465957ATo achieve the effect of random selectionImprove the problem that the interaction cannot be realizedTelevision system detailsColor television detailsTelevision stationHuman–computer interaction
The invention relates to a system and a controlling method for realizing remote control interaction in a virtual three-dimensional scene. An interactive control system solves how to carry out the interaction and control on a virtual studio scene, animation and an object in the scene by an operator. The system mainly comprises three modules: first, a three-dimensional producing and real-time rendering module; second, a playing and controlling module; third, an interactive module. The interactive module includes subsystems such as a wireless remote control subsystem, a voice recognizing subsystem, an image recognizing subsystem, a position tracking subsystem (an action recognizing subsystem), a touch screen subsystem (a visual multimedia playing and controlling interface and a multi-point touch controlling method are provided), and the like. A three-dimensional real-time rendering engine can be driven by the playing and controlling module by the operator through various interactive methods, thus realizing the selectively instant playing of the virtual scene and the controlling of the virtual object. The system can be applied to virtual studios of television stations and other virtual interactive demonstrating occasions.

Fast rendering method for virtual scene and model

ActiveCN107103638AMaterial parameters can be modifiedImprove efficiencyImage rendering3D-image renderingUV mapping3D modeling
The invention discloses a fast rendering method and device for a virtual scene and a model. The method comprises steps of firstly obtaining the rendering request of the virtual scene and the model to be rendered and the standard material library; creating a read and write file including the corresponding relation among the scene parameter, the model and the material according to the rendering request, and selecting a material corresponding to the model to be rendered from the pre-established standard material library after loading; setting and adjusting the scene parameter according to the rendering request, rendering the model according to the selected material and adjusting the material parameter to complete the rendering satisfying the specified rendering request; when a single model corresponds to a plurality of materials, directly subjecting the plurality of materials to a three-dimensional presence UV mapping on the surface of the three-dimensional model; and generating a high light effect and its corresponding material by the hand-drawn trajectory according to the rendering request, and rendering the model's high light effect. The method has the advantages of high efficiency, openness, automation, integration of tools, light weight, sustainability, and the like on the basis of greatly improving the efficiency of virtual scene and model rendering.

Tobacco fiber paper filter stick and preparation method thereof

The invention relates to the field of tobacco filter sticks, and discloses a tobacco fiber paper filter stick and a preparation method of the tobacco fiber paper filter stick. The paper filter stick is composed of a filter element and forming paper, wherein the filter element is obtained by coiling paper fiber, the paper fiber is tobacco fiber pulp and long fiber pulp which are obtained by grinding tobacco raw materials and long fiber raw materials into liquid, then the tobacco fiber pulp and the long fiber pulp are subjected to pulp matching, sheet making, squeezing and drying to be manufactured into a fiber paper base, and the tobacco fiber paper filter stick can be obtained through smearing, drying and rolling. On the basis of wet process papermaking, tobacco fiber and long fiber are mixed according to a proper proportion in the pulp matching stage of papermaking, and the obtained paper filter stick not only has higher tar and nicotine removing capacity than a cellulose acetate filter stick, but also can successfully eliminate wooden offensive odor of the long fiber. Raw materials of the filter stick come from natural plants, and therefore the filter stick only has the scent of tobacco and does not have the scent of paper or chemical fiber, the color of the filter stick is consistent to that of cut tobacco of cigarettes, and the filter stick has the texture of natural material of tobacco and guides a new direction for the technical field of cigarettes.
