The rendering server can be a cloud server, a three-dimensional machine room model to be used is stored in a model management module of the rendering server, and the rendering server can automatically select and allocate appropriate computing resources according to the model scale to realize rendering. After receiving the rendering instruction, the rendering server finds out the computing resource where the model to be rendered is located, searches for a rendering image in a cache pool, and if the rendering image exists in the cache pool, directly pushes the rendering image to a terminal device; if the rendering image does not exist in the cache pool, rendering is directly carried out in real time, the rendering image is directly pushed to the terminal equipment, and the rendering image is placed in the cache pool.
Step 120, receiving the rendered image sent by the pushing server and displaying the rendered image; the rendering image is a three-dimensional image which is obtained by rendering the target model by the rendering server based on the first rendering instruction and is sent to the pushing server.
It can be understood that after receiving the first rendering instruction, the rendering engine of the rendering server finds the machine room model from the model management according to the first rendering instruction, and invokes the computing resource allocated by the computing resource scheduling engine to perform real-time rendering of the image, so as to obtain a rendered image. After the rendered image is obtained, the rendered image is sent to a cache pool for caching by the rendering engine so as to be called next time, and the rendered image is sent to a pushing server so as to send a first rendering instruction to the terminal equipment through the pushing server.
And 130, acquiring a click command under the condition that the rendered image is clicked, and acquiring corresponding two-dimensional image data from an image data server based on the click command.
It can be appreciated that the user obtains the server ID by clicking on the server identifier on the rendered image, and invokes the interface of the image data server through the server ID to obtain the two-dimensional image data in the image data server. The image data server may be a local server.
Step 140, sending a second rendering instruction including the clicked object to the push server, so as to send the second rendering instruction to the rendering server based on the push server.

It can be understood that the rendering engine converts the three-dimensional coordinates of the click object contained in the second rendering instruction into two-dimensional coordinates of the image through the matrix projection algorithm of OpenGL, the rendering server sends the two-dimensional coordinates of the converted image to the pushing server, and the two-dimensional coordinates of the image are sent to the terminal device through the pushing server so as to be used for rendering the chart by the terminal device, so that the data visualization operation is completed.
In some embodiments, the data visualization method further comprises:
before the first rendering instruction is sent to the pushing server, a webtc protocol communication channel is established between terminal equipment and the pushing server, so that the first rendering instruction and the second rendering instruction are sent to the pushing server from the terminal equipment based on the webtc protocol communication channel, and the rendered image and the two-dimensional coordinates of the image sent by the pushing server are received.
It can be understood that a user can open an operation page on the terminal device, load a front-end rendering canvas and a rear-end image canvas, the rear-end image canvas and the push server establish a webrtc protocol communication channel for receiving the image pushed by the push server, and the event interaction center and the push server establish a webrtc protocol communication channel for sending instructions.
In some embodiments, the method for visualizing data, the presenting the rendered image, comprises:
displaying the rendered image to a browser based on a backend image canvas;
the chart rendering based on the two-dimensional image data and the two-dimensional image coordinates comprises the following steps:
And performing chart rendering on a front-end rendering canvas based on the two-dimensional image data and the two-dimensional coordinates of the image.
It is appreciated that the backend image canvas may render rendered images to the browser via the webtc protocol.
Two broad categories of visualization components, front-end rendering components and back-end rendering components, are defined for the rendering mode of the visualization components. The back-end rendering component is typically a three-dimensional component, such as a three-dimensional earth, a three-dimensional GIS, a custom three-dimensional model, and so on. The front-end rendering component is typically an echartite chart, text, picture, etc., two-dimensional web component. The visual page is composed of two layers of canvas, a bottom layer of canvas (i.e. a back end image canvas) is used for placing the back end rendering component, and a top layer of canvas (i.e. a front end rendering canvas) is used for placing the front end rendering component. The problem of interaction operation such as coordinate mapping, event transfer and the like between different types of components of different canvas is solved between the two layers of canvas through the event interaction center.
Event delivery typically occurs when a user clicks or enters an operation on a canvas, converting to different rendering instructions, including rotation, movement, scaling, display, hiding, switching, etc., of the three-dimensional model, according to different event needs.
In some embodiments, the two-dimensional coordinates of the image are obtained by converting three-dimensional coordinates of the click object by the rendering server based on a matrix projection algorithm.
It will be appreciated that coordinate mapping typically occurs after an underlying canvas drag event occurs and that the two-dimensional component rendered by the backend image canvas needs to be positioned in real time to some fixed location of the three-dimensional component. The two-dimensional component and the three-dimensional component adopt different coordinate systems, so that coordinate conversion is needed. The method comprises the specific steps that the two-dimensional component records the position of the two-dimensional component in a three-dimensional coordinate system and sends the position of the two-dimensional component to a rendering server, and the rendering server converts the coordinates of the three-dimensional component into two-dimensional component coordinates through a matrix projection algorithm of OpenGL in the rendering process and returns the two-dimensional component coordinates to terminal equipment for positioning and using the two-dimensional component on a front-end rendering canvas.

receiving new two-dimensional coordinates of the image sent by the pushing server, and performing chart rendering based on the two-dimensional image data and the new two-dimensional coordinates of the image; the new two-dimensional coordinates of the image are obtained by converting the three-dimensional coordinates of the dragging object by the rendering server based on the third rendering instruction and are sent to the pushing server.
It can be understood that when a user drags a page on the terminal device, an instruction (namely, a third rendering instruction) of model movement generated by the event interaction center of the terminal device is transmitted to the rendering server to render the target model, so as to obtain new two-dimensional coordinates of the image, the new two-dimensional coordinates of the image are pushed to the terminal device through the pushing server, the terminal device utilizes the two-dimensional image data acquired before and the new two-dimensional coordinates of the image acquired at present to render a chart on a front rendering canvas, and the two-dimensional covering is rendered at a new position.
