The present invention discloses an image rendering method and a system. The method comprises an acquisition step for acquiring the image frames of a to-be-rendered image, wherein the image frames comprise a plurality of key frames and a plurality of reference frames, one key frame corresponds to a plurality of reference frames, the key frames represent the particular scene optical information, and the reference frames represent the depth information of key frames; a processing step for acquiring two motion fields according to the plurality of key frames and the plurality of reference frames, wherein the two motion fields comprise a motion field between key frames and reference frames and a motion field between different key frames; and a rendering step for obtaining a rendered image through rendering the plurality of processed key frames. According to the invention, based on two motion fields different in scale, the 360-degree panoramic image rendering effect is realized.

The invention provides an image rendering method and apparatus, and relates to the image processing field, aiming at solving the problem that as a filter with good effect includes too many layers, real time rending is difficult to guarantee. The image rendering method includes the steps: receiving rendering indication, for an image to be rendered, input by a user; acquiring the original pixel value corresponding to each pixel for the image to be rendered; according to a preset mapping table, acquiring the target pixel value corresponding to each original pixel value; and according to the target pixel value, modifying the image to be rendered, and obtaining the image after rendering. The image rendering method and apparatus can be applied to the editing process of images and videos.

The invention relates to a page rendering method and device based on a template engine. The method comprises the following steps of monitoring a message sent by a main thread of the template engine through a working thread monitoring template; receiving the message through the working thread and parsing the message to obtain a pass parameter; making the working thread generate an HTML character string according to the pass parameter; and sending the HTML character string to the main thread of the template engine through the working thread in order to make the main thread of the template enginedisplay the page according to the HTML character string. According to the page rendering method and device based on the template engine, the rendering of the page can be accelerated, the rendering performance of the page can be improved and the condition of lag of the page can be avoided.

The invention relates to the technical field of two-dimensional code generation, and discloses a multi-thread two-dimensional code generation algorithm based on Web Workers. The multi-thread two-dimensional code generation algorithm comprises the following steps that: a browser end receives a two-dimensional code generation request, and acquires two-dimensional code generation data according to the two-dimensional code generation request; encoding the two-dimensional code generation data, and taking the encoded data as two-dimensional code content information parameters; packaging the two-dimensional code content information parameter and a preset two-dimensional code parameter into a parameter object by usinga JavaScript main thread of the browser, and instantiating a Worker sub-thread; sending the parameter object in the JavaScript main thread to the Worker sub-thread; analyzing the received parameter object and calculating a corresponding two-dimensional code matrix by the Worker sub-thread; traversing the two-dimensional code matrix by the Worker sub-thread, and rendering the two-dimensional code by using a (rect) label of the SVG to obtain an SVG image of the two-dimensional code; and the Worker sub-thread sends the SVG image back to the JavaScript main thread, and the JavaScript main thread directly displays the two-dimensional code on an HTML page in an inline SVG mode.the multi-thread two-dimensional code generation algorithm improves the generation efficiency of the two-dimensional code.

The embodiment of the invention discloses a bullet screen rendering method and device, computer equipment and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: acquiring target bullet screens within a target duration; drawing the target bullet screens in the same bitmap to obtain target bitmaps; uploading target textures corresponding to the target bitmaps to a video memory, wherein the target textures comprise barrage textures corresponding to the target bullet screens; and in response to the bullet screens refreshing signal, rendering the barrage texture in the target texture by calling a rendering instruction in the graphic program interface. According to the embodiment of the invention, the target barrage is drawn in the samebitmap; a primary texture uploading instruction is called to upload the target texture to a video memory; the texture uploading frequency is reduced, in the whole barrage rendering process, batch bullet screen rendering can be achieved only by calling the rendering instruction once, processor overload caused by frequent calling of the rendering instruction is avoided, the situation that playing isnot smooth when the number of bullet screens is large is relieved, and the bullet screen playing fluency is improved.

The embodiment of the invention provides a web page rendering method, a device and a storage medium. The web page rendering method comprises the following steps: receiving a triggering operation acting on a preset control, the preset control being located in an AR scene; acquiring a web page to be rendered according to the triggering operation; rendering the above page in the AR scene. The embodiment of the invention can realize rendering a web page in an AR scene.

The invention discloses a three-dimensional geographic information model rendering method and system based on a generative adversarial network, equipment and a storage medium. The method comprises a geographic information three-dimensional modeling step, a three-dimensional model generation training step, an all-terrain element matching step, a three-dimensional geographic information collaborative rendering step and a three-dimensional geographic information overall rendering step. Generation of the geographic information model is achieved through an artificial intelligence method and a generative adversarial network framework, all-terrain element matching and similar terrain theme part extraction are achieved through a sliding matching mode, non-repeated rendering of similar three-dimensional geographic information model main body parts is achieved through a mode of pre-rendering in a cache in advance, therefore, the rendering speed of the three-dimensional object is improved.

The invention discloses a large-space multi-user interaction integrated system based on cloud rendering and a use method thereof, and the large-space multi-user interaction integrated system based on cloud rendering comprises a supporting assembly, a first movement capture system, a second movement capture system, a gateway SDK, a cloud rendering server and a VR terminal. According to the scheme, the gateway SDK is used for the unified external interface, a developer can directly connect the unified external interface of the gateway SDK, the problem that development becomes complex due to the fact that data between different movement capture systems are not subjected to standardized processing is avoided. Meanwhile, movement rendering is achieved through the cloud rendering server, the existing backpack computer rendering form is avoided, and the development efficiency is improved. A user needs to carry a heavy knapsack computer, use is convenient, and the practical experience of the user is improved.
