Description

Technical Field

[0001] Embodiments of the present invention relate to the field of visual analysis of computer technology, and in particular, to an image rendering method, apparatus, electronic device, and medium. Background Art

[0002] With the in-depth research on numerical simulation calculation methods and the continuous improvement of the computing power of high-performance computers, the scale of simulation has also increased, and the amount of data generated by simulation calculations has become larger and larger. Simulating an industrial-scale device may require more than a billion particles and more than a million grids, and more than ten million time steps on the time scale. Therefore, it is necessary to process a large amount of data (if the data information of one billion particles is stored in single-precision floating-point numbers, each time step requires about 260 GB of data).

[0003] Since scientific visualization is an effective method for analyzing numerical simulation result data and can present visualization images with high precision, its visualization analysis tool is an important means for deeply mining and analyzing result data. The cross-section analysis tool is a kind of visualization analysis tool. By calculating the cross-section of the simulation object at a specified position, users can intuitively observe the inside of the simulation object, which helps to deeply analyze the characteristic information of the simulation object. However, when visualizing and analyzing numerical simulation result data and using the cross-section analysis tool to process a large amount of data, it increases the algorithm complexity and computational amount in the three-dimensional reproduction process, reduces the processing speed, and at the same time poses great challenges in terms of device computing power and I / O speed.

[0057] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all structures.

[0058] Embodiment 1

[0059] Figure 1 is a flowchart of an image rendering method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of three-dimensional reproduction and cross-section analysis when visualizing massive data. This method can be executed by an image rendering device, and the device can be implemented in software and / or hardware, and can be specifically inherited in an electronic device with storage and computing capabilities for image rendering.

[0060] As Figure 1 shown, an image rendering method is provided, which is applied to a client and specifically includes the following steps:

[0061] S110, receive a rendering request from a user, where the rendering request includes rendering parameters;

[0062] In an embodiment of the present invention, the rendering request from the user can be understood as a request sent when it is necessary to render simulation result data. Among them, the simulation result data can be the simulation result data of the riser section of any reactor device, or the result data generated by simulating other devices, or the data stored in the numerical simulation result database. The rendering parameters can be understood as the data parameters used when rendering the simulation result data, such as the storage location of the case data, the case scale, the start time step of the simulation, the end time step of the simulation, the simulation interval time step, the height of the display window, the width of the display window, etc. The image depth value can be understood as the distance of a pixel block from the acquisition device or apparatus in three-dimensional space when collecting an image in three-dimensional space. Among them, the larger the depth value, the farther the pixel block is from the acquisition device or apparatus. The color information can be understood as the information of the three color channels red (Red), green (Green), and blue (Blue) in the RGB color mode and various colors obtained by superimposing them on each other.

[0063] In an embodiment of the present invention, when the simulation result data in any of the above-mentioned reactor devices, other devices, or simulation result databases needs to be rendered, the client sends the rendering request to the server, and the server starts rendering after receiving the rendering request.

[0064] In an embodiment of the present invention, the specific program annotation content of the rendering parameters in the rendering request is as follows:

[0065]

[0066]

[0067] S120, send the rendering parameters to the server and obtain the image depth value and color information from the server;

[0068] In an embodiment of the present invention, the server can be understood as a computer with a configured IP address and port number where the rendering program corresponding to the client is deployed. Among them, the server can be pre-set, or specified by the client according to the data processing ability of the rendering program. The image depth value and color information of the server can be understood as the corresponding image depth value and color information calculated by the rendering program on the server according to the rendering parameters.

[0069] In an embodiment of the present invention, the client receives a rendering request from a user, and sends the rendering parameters in the rendering request to a rendering program on the server. The rendering program on the server calculates the image depth value and color information corresponding to the rendering parameters according to the rendering parameters, and returns the image depth value and color information corresponding to the rendering request to the client.

[0070] Step S130: Send the cross-section position information of the three-dimensional reproduction image corresponding to the image depth value and color information to the server, and obtain the cross-section depth value and color information from the server;

[0071] In an embodiment of the present invention, the three-dimensional reproduction image can be understood as an image with three-dimensional information presented by the client according to the rendering request. The cross-section position information can be understood as the position information on the three-dimensional reproduction image that needs to be observed. The cross-section depth value and color information can be understood as the image depth value and color information corresponding to the cross-section calculated according to the cross-section position information.

[0072] In an embodiment of the present invention, the client displays the three-dimensional reproduction image corresponding to the simulation result data according to the received image depth value and color information. The client sends the cross-section position information corresponding to the three-dimensional reproduction image in the cross-section analysis tool to the server. The rendering program on the server uses the cross-section position information as the overlay rendering parameter, calculates the cross-section depth value and color information according to the cross-section position information, and sends the cross-section depth value and color information to the client.

[0073] In an embodiment of the present invention, the cross-section position information corresponding to the three-dimensional reproduction image in the client cross-section analysis tool may be the cross-section position information corresponding to multiple normal position information in the cross-section analysis tool.

[0074] In an embodiment of the present invention, the specific program annotation content of the cross-section position information is as follows:

[0075]

[0076] Step S140: Overlay the cross-section depth value and color information on the three-dimensional reproduction image as the rendering result.

[0077] In an embodiment of the present invention, the rendering result can be understood as a three-dimensional reproduction image after the cross-section depth value and color information are overlaid. Among them, the overlaid three-dimensional image not only has the three-dimensional features in the simulation result data in the rendering request, but also has the two-dimensional image features in the cross-section analysis tool.

[0078] In an embodiment of the present invention, the client superimposes the cross-section depth value and color information sent by the server on the three-dimensional reproduction image, so as to obtain a superimposed three-dimensional reproduction image that can directly observe the inside of the simulation object. The three-dimensional reproduction image is obtained by three-dimensionally reconstructing and reproducing the simulation result data through the image depth value and color information in the rendering request.

[0079] In an embodiment of the present invention, the image depth value and color information not only include the depth value of the pixel block in the image depth value and color information, but also include the color information in the image depth value and color information. When the client superimposes the cross-section depth value and color information sent by the server on the three-dimensional reproduction image, what is read in is not only the depth value of the corresponding pixel block in the cross-section depth value and color information, but also the color information corresponding to the depth value of the corresponding pixel block.

[0080] Further, the three-dimensional reproduction image corresponding to the image depth value and color information includes:

[0081] Receiving the image depth value and color information of the server;

[0082] If, when the image depth value and color information are read in, the original depth value of the pixel block is greater than the depth value of the corresponding pixel block in the image depth value and color information, then discard the original depth value of the pixel block and the original pixel block color information, and update it to the image depth value and color information.

[0083] In an embodiment of the present invention, the original depth value of the pixel block can be understood as the depth value of the pixel block in the display window or display device before the client reads in the image depth value and color information. The depth value of the pixel block corresponding to the image depth value and color information can be understood as the depth value of the pixel block in the image depth value and color information calculated according to the rendering parameters sent by the server to the client.

[0084] In an embodiment of the present invention, the client receives the image depth value and color information of the server, and judges whether the depth value of the pixel block in the image depth value and color information is less than the original depth value of the pixel block in the client's display window or display device before reading in the image depth value and color information. If the depth value of the pixel block in the image depth value and color information is less than the original depth value of the pixel block in the client's display window or display device, then discard the original depth value of the pixel block in the display window or display device, and read in the image depth value and color information into the pixel block in the display window or display device, that is, update the original depth value and the original pixel block color information of the pixel block in the display window or display device to the image depth and color information.

[0085] Further, before sending the cross-section position information of the three-dimensional reproduction image corresponding to the image depth value and color information to the server, it further includes:

[0086] Change the normal position of the initial horizontal section of the three-dimensional reproduction image, and determine the section position information corresponding to the normal.

[0087] In the embodiments of the present invention, the initial horizontal section can be understood as the cross-section in the horizontal direction of the three-dimensional reproduction image. Among them, the initial horizontal section is generally located at the top of the three-dimensional reproduction image, and can also be located at other positions. The normal can be understood as the normal corresponding to the initial horizontal section.

[0088] In the embodiments of the present invention, the client determines the section position information according to the normal position of the initial horizontal section of the three-dimensional reproduction image in the cross-section analysis tool. In fact, it is to change the normal position of the initial horizontal section of the three-dimensional reproduction image, that is, to change the position of the initial horizontal section by rotating the normal, and obtain the section position information corresponding to different section positions, so as to determine the internal feature information of the three-dimensional reproduction image that needs to be observed.

[0089] Further, before receiving the rendering request from the user, the rendering request includes rendering parameters, and further includes:

[0090] The client is monitored by the rendering program on the server;

[0091] If the rendering program on the server monitors that the client receives the rendering request from the user, the rendering program on the server establishes a connection with the server specified by the client.

[0092] In the embodiments of the present invention, the rendering program on the server can be understood as a calculation program or software that can generate a three-dimensional image based on the rendering parameters in the rendering request.

[0093] In the embodiments of the present invention, before starting the client display window and the display device, the rendering program on the server corresponding to the client monitors whether the client receives the rendering request from the user; if the rendering program on the server monitors that the client receives the rendering request from the user, the client starts the display window or the display device, and establishes a connection between the rendering program on the server and the server specified by the client.

[0094] Further, before establishing a connection between the rendering program on the server and the server specified by the client, it further includes:

[0095] Determine the server specified by the client according to the rendering request.

[0096] In the embodiments of the present invention, after the client starts the display window or the display device, the client determines the server rendering program that needs to be displayed by the client according to the rendering request, and establishes a connection between the server as the server specified by the client and the rendering program.

[0097] In the embodiments of the present invention, establishing a connection between the server specified by the client and the rendering program according to the rendering request may mean that the client and the rendering program are not on the same computer. Specifically, the front-end display program may be deployed on one computer, which is abbreviated as the client, and the rendering program may be deployed on another computer, which is abbreviated as the server. The specific configuration of the client is as follows: The CPU is an Intel Core i5-9500 3.0GHz, the memory is 8GB, the hard disk is a combination of a 56G solid-state drive and a 1TB ordinary hard disk, the graphics card is an NVIDIA P620, and the operating system is 64-bit Windows 10. The specific configuration of the server is as follows: The CPU is an Intel Xeon E5-2680 v3 2.5GHz, the memory is 64GB, the hard disk is 8TB, the graphics card is two NVIDIA K80s, and the operating system is 64-bit CentOS 7.4. According to the rendering request, the client establishes a connection with the rendering program on the server. Among them, the client as the front-end display program and the rendering program may be deployed on the same computer, and this computer is both the client and the server. The specific configuration of the computer is as follows: The CPU is an Intel Xeon E5-2680 v3 2.5GHz, the memory is 64GB, the hard disk is 8TB, the graphics card is two NVIDIA K80s, and the operating system is 64-bit Windows 10.

[0098] Further, the overlaying the cross-section depth value and the color information on the three-dimensional reproduction image as the rendering result includes:

[0099] Receiving the cross-section depth value and the color information from the server;

[0100] If, when the cross-section depth value and the color information are read in, the depth value of the pixel block in the three-dimensional reproduction image is greater than the depth value of the corresponding pixel block in the cross-section depth value and the color information, then discard the depth value of the pixel block in the three-dimensional reproduction image and update the original pixel block color information to the cross-section depth value and the color information.

[0101] In the embodiments of the present invention, the depth value of the pixel block in the three-dimensional reproduction image can be understood as the depth value corresponding to each pixel block in the three-dimensional reproduction image displayed by the display device or display window of the client. The original pixel block color information can be understood as the color information corresponding to the depth value of the pixel block in the three-dimensional reproduction image.

[0102] In an embodiment of the present invention, the client receives the depth value and color information of the cross-sectional image from the server. When reading in the depth value and color information of the cross-sectional image, the client needs to determine whether the depth value of the pixel block in the three-dimensional reproduction image displayed by the client is greater than the depth value of the corresponding pixel block in the depth value and color information of the cross-sectional image; if the depth of the pixel block in the three-dimensional reproduction image displayed by the client is greater than the depth value of the corresponding pixel block in the depth value and color information of the cross-sectional image, then discard the depth value of the pixel block in the three-dimensional image and update it to the depth value and color information of the cross-sectional image.

[0103] Further, after superimposing the cross-sectional depth value and color information on the three-dimensional reproduction image as the rendering result, the following steps are also included:

[0104] If there are unrendered parameters in the rendering parameters, then send the unrendered parameters to the server and obtain the image depth value and color information corresponding to the unrendered parameters from the server;

[0105] According to the image depth value and color information corresponding to the unrendered parameters and the unrendered parameters, superimpose them on the rendering result to obtain a new rendering result.

[0106] In an embodiment of the present invention, the unrendered parameters can be understood as the uncalculated rendering parameters in the rendering parameters before or after being sent to the server, or can also be the real-time updated rendering parameters.

[0107] In an embodiment of the present invention, after the client superimposes the cross-sectional depth value and color information on the three-dimensional reproduction image as the rendering result, it is necessary to determine again whether there are unrendered parameters in the rendering parameters. If there are unrendered parameters in the rendering parameters, it means that the rendering is incomplete. It is necessary to send the unrendered parameters to the server and obtain the image depth value and color information corresponding to the unrendered parameters from the server. Superimpose the image depth value and color information corresponding to the unrendered parameters on the rendering result to obtain a new rendering result.

[0108] Figure 1A It is a schematic flowchart of an image rendering method in the first embodiment of the present invention, as Figure 1AAs shown in the figure, the rendering program on the server monitors that the client receives the user's rendering request, starts the client display window, the client sends the rendering parameters to the server, and the rendering program on the server calculates the image depth value and color information corresponding to the rendering request based on the received rendering parameters and sends them to the client. The client presents the three-dimensional reproduction image in the display window according to the image depth value and color information. Determine the cross-section position information according to the normal position vector in the cross-section analysis tool, send the cross-section position information of the three-dimensional reproduction image to the server, and the rendering program on the server calculates the corresponding cross-section depth value and color information according to the cross-section position information and sends the cross-section depth value and color information to the client. The client superimposes the cross-section depth value and color information on the three-dimensional reproduction image as the rendering result. Determine whether there are unrendered parameters in the rendering parameters. If there are unrendered parameters in the rendering parameters, send the unrendered parameters to the server, and the rendering program on the server calculates the image depth value and color information corresponding to the unrendered parameters, and superimposes the image depth value and color information corresponding to the unrendered parameters on the rendering result to obtain a new rendering result.

[0109] The present invention receives a user's rendering request, the rendering request includes rendering parameters; sends the rendering parameters to a server and obtains an image depth value and color information from the server; sends cross-section position information of a three-dimensional reproduction image corresponding to the image depth value and color information to the server and obtains a cross-section depth value and color information from the server; superimposes the cross-section depth value and color information on the three-dimensional reproduction image as a rendering result; solves the problems that in visual analysis of numerical simulation result data and when using a cross-section analysis tool to process massive data, the algorithm complexity and calculation amount are large, the processing speed is slow, and there are huge challenges in terms of device computing power and I / O speed, etc.; realizes that when rendering the results of massive numerical calculation results in three dimensions, the three-dimensional characteristics of the scene are completely retained, the performance requirements for computing devices are reduced, and the data processing speed and accuracy are further improved.
