[0002] Computer simulation technology is widely used in the research and analysis of various fields such as society, economy, military, transportation, architecture, and industrial production. During the process of calculating and solving the simulation model by means of a computer, it is usually necessary to visualize the simulation scene and simulation object instances so as to facilitate people to observe and understand the state and behavior of the simulation system. In order to realize the simulation scene animation, people often use professional visualization software to visually display the simulation scene and simulation object instances. However, people need to connect the simulation scene and data to professional visualization software, and even need to perform data format conversion, or re-develop the simulation model in professional visualization software. Using professional software for visualizing simulation scene animation has problems of economic cost and development time cost, and even has requirements and limitations on the content of visualizing simulation scene animation, which cannot meet personalized customization.

[0003] Therefore, it is not suitable to use professional visualization software to design and develop simulation scene animation for small-scale simulation systems. And a simple and easy-to-use simulation scene animation visualization method that supports flexible design and on-demand customized development is more suitable for visualizing the simulation scene animation of small-scale simulation systems.

Description of the Drawings

[0048] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on the structures shown in these drawings.

[0049] Figure 1 is the overall framework diagram of the two-dimensional simulation scene animation visualization method provided by an embodiment;

[0050] Figure 2 is the flowchart for periodically updating and drawing the current simulation scene in the simulation program view provided by an embodiment. Detailed Description of the Embodiments

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0052] In one embodiment, referring to Figure 1 , a two-dimensional simulation scene animation visualization method is provided, including:

[0053] Input a bitmap, determine the pixel size and spatial position of the simulation object described by the bitmap and the graphic images in the bitmap, and generate bitmap space data;

[0054] Load the bitmap in the simulation program, obtain the current brush of the simulation program view, and initialize the memory brush and memory canvas of the simulation program view according to the bitmap;

[0055] Set a timer to periodically update and draw the current simulation scene in the simulation program view;

[0056] Read the bitmap space data, obtain the pixel size and pixel position of the simulation object described by the bitmap and the graphic images in the bitmap, initialize the data of the simulation object in the current simulation scene, and generate a simulation object instance;

[0057] Draw the graphic image of the simulation object instance in the simulation scene with the bitmap as the background map of the simulation scene;

[0058] Update and draw the graphic image of the simulation object in the simulation scene according to the state and position changes of the simulation object instance, and realize the animation visualization of the simulation scene.

[0059] When updating the current simulation scenario in the simulation program view, first use the bitmap mapping method to overwrite and update the previous simulation scenario in the simulation program view, and then draw the graphic image of the simulation object instance in the updated current simulation scenario according to its latest state and position. As the simulation time progresses, the state and position of the simulation object instance change continuously, and at the same time, the simulation scenario is continuously updated and drawn to form the animation visualization effect of the simulation scenario.

[0060] In one embodiment, a method for generating bitmap spatial data is proposed. In essence, it is based on the spatial modeling of bitmap pixels to clarify the spatial size of the two-dimensional simulation scenario and the spatial position and pixel size of simulation objects such as buildings, facilities, and roads described by the graphic images in the bitmap. Specifically, it includes:

[0061] Taking the upper left vertex of the bitmap as the origin, the right direction as the positive direction of the abscissa, the lower direction as the positive direction of the ordinate, and using pixels as the standard unit of spatial distance, establish a spatial coordinate model;

[0062] Determine the pixel size of the bitmap and use it as the spatial range of the simulation scenario;

[0063] Determine the pixel size and spatial position of the simulation objects described by the graphic images in the bitmap;

[0064] Describe and store the bitmap and the pixel size and spatial position of the simulation objects described by the graphic images in the bitmap in a formatted XML document to obtain a bitmap pixel spatial data format file, which is used to format and describe the spatial position information of the simulation scenario and save the spatial data of the simulation scenario objects. The basic information of the bitmap and the graphic images in the bitmap is recorded, including: name, position, size, as the bitmap spatial data.

[0065] Regarding the pixel size and spatial position of the simulation objects described by the graphic images in the bitmap, one embodiment proposes to describe the pixel size and spatial position of the simulation objects described by the graphic images in the bitmap with a rectangle, that is, to determine the spatial position and size of the graphic image through the upper left vertex pixel, pixel width, and pixel height of the graphic image in the bitmap.

[0066] For example, in one embodiment, move the mouse to the upper left vertex of the graphic image in the bitmap in the drawing software to determine the pixel position of the graphic image, and then move the mouse to the lower right vertex of the graphic image to determine the pixel width and height of the graphic image. According to the pixel position of the upper left vertex of the graphic image and the width and height of the graphic image, form a rectangle to determine the spatial position and size of the graphic image in the bitmap. Repeat this step to determine the pixel size and spatial position of all simulation objects such as buildings, infrastructure, places, and roads in the bitmap.

[0067] Record data such as the pixel size of the bitmap and the pixel size and spatial position of the simulated object described by the graphic image in the bitmap into an XML data file. The XML data file records the bitmap number, scene name, bitmap file name, pixel width and height, as well as data such as the building number, name, type, pixel position of the upper left vertex, width and height of the building rectangle, etc.

[0068] In the above embodiment, an XML format file is used to store the pixel spatial position and size data of the bitmap and the graphic image, which supports the initialization of the simulation scene object.

[0069] Establish a simulation scene model according to the bitmap and its bitmap spatial data. The simulation scene model reasonably organizes and manages bitmaps, graphic images, brushes, canvases, scene building objects, and simulation objects, completes the tiled drawing of the bitmap to simulate the scene background, draws simulation objects on the scene background, and copies the drawn simulation scene to the brush of the simulation program view. At the same time, the simulation scene model stores the position information of spatial elements such as buildings and facilities in the scene, can provide scene element information for the simulation model object, and supports the spatial cognition and spatial activities of the simulation object in the scene.

[0070] Initialize the simulation program, including creating brushes and canvases in the simulation program, mainly including the following types: (1) The current brush and canvas of the simulation program view are directly associated with the computer screen resources, that is, the brush and canvas displayed when the simulation program view is explicitly displayed on the screen; (2) The memory brush and memory canvas of the simulation program view exist in the simulation program memory and are used to temporarily store the simulation scene to be explicitly displayed; (3) The background brush and background canvas of the simulation scene model exist in the simulation scene model memory and are used to store the simulation scene background map, and paste the background map tiled to the simulation scene when the simulation scene needs to be updated; (4) The main brush and main canvas of the simulation scene model exist in the memory of the simulation scene model and are used to draw the simulation scene, receive the background map pasted by the background brush, and draw graphic images for the simulation object instance.

[0071] The above several types of brushes and canvases are created during the initialization of the simulation program, and the modes of the brushes and canvases should be compatible with the current brush and canvas of the simulation program view. The background canvas of the simulation scene model is responsible for loading the bitmap file. Under the scheduling of the algorithm, the several types of brushes and canvases draw, update, and transfer the simulation scene to realize the animation visualization of the simulation scene.

[0072] Initialize the memory brush and memory canvas of the simulation program view according to the bitmap, including: initializing the memory canvas of the simulation program view in bitmap format and using the memory canvas to load the bitmap; initializing the memory brush of the simulation program view in the format of the current brush of the simulation program view and using the memory brush to load the memory canvas.

[0073] When the simulation scenario model draws or updates the simulation scenario, it first pastes its background canvas to its main brush, and then loops to draw the graphic images of the simulation object instances. When drawing the graphic images of the simulation object instances in a simulation scenario with a bitmap as the background image of the simulation scenario, according to the pixel size and spatial position of the simulation object, the graphic images of the simulation object instances are drawn at the corresponding positions in the simulation scenario with a bitmap as the background image of the simulation scenario. After the simulation scenario model completes the update drawing of the simulation scenario, it pastes the new simulation scenario to the memory brush of the simulation program view.

[0074] After the memory brush of the simulation program view receives the updated simulation scenario, it should immediately update to the current brush of the simulation program view and be displayed on the computer screen. However, since the calculation speed of the simulation model may be too fast, the simulation scenario is updated too quickly, resulting in the computer screen display resources not being able to keep up with the update speed of the simulation scenario, so that the simulation scenario animation cannot be normally visualized on the computer screen. Therefore, a timer is used in the simulation program to count, and at fixed unit time intervals, the memory brush of the simulation program view is triggered to paste the latest simulation scenario to the current brush of the simulation program view to ensure the normal visualization of the simulation scenario animation. Specifically, referring to Figure 2 , in one embodiment, a timer is set to achieve periodic update and drawing of the current simulation scenario in the simulation program view. The method includes:

[0075] Set a timer and enter the timer timing loop period. At the same time, monitor in real time whether there are human-computer interaction operations on the simulation program interface. The human-computer interaction operations include but are not limited to operations such as moving, covering and restoring on the simulation program interface;

[0076] Judge whether the current timing period of the timer has ended. If so, paste the memory brush of the simulation program view to the current brush of the simulation program view, update the current simulation scenario in the simulation program view, and enter the next new timing period of the timer;

[0077] Judge in real time whether it is detected that there are human-computer interaction operations on the simulation program interface. If so, paste the memory brush of the simulation program view to the current brush of the simulation program view and update the current simulation scenario in the simulation program view;

[0078] Judge whether the simulation program is closed. If so, exit the timer timing and end the process.

[0079] The present invention uses a memory brush and a memory canvas to temporarily store the latest simulation scenario, and according to the visualization algorithm, the latest simulation scenario in the memory brush is pasted to the current brush of the simulation program view at a set moment to update the simulation scenario animation.

[0080] In one embodiment, a simulation program is newly created in Visual Studio software. Select the MFC application and the single-document application type. In the generated class options, select CScrollView as the view base class.

[0081] Initialize the simulation program and create member variables such as the paintbrush and canvas in the simulation program, including the memory paintbrush "CDC_memDC", the memory canvas "CBitmap_memBitMap", and the bitmap "BITMAP_bitMap". The paintbrush and canvas in the simulation program mainly include the following types: (1) The current paintbrush and canvas of the simulation program view, which are directly associated with the computer screen resources, that is, the paintbrush and canvas displayed when the simulation program view is explicitly shown on the screen; (2) The memory paintbrush and memory canvas of the simulation program view, which exist in the simulation program memory and are used to temporarily store the simulation scenarios to be explicitly shown; (3) The background paintbrush and background canvas of the simulation scenario model, which exist in the simulation scenario model memory and are used to store the simulation scenario background map. When the simulation scenario needs to be updated, the background map is tiled and pasted onto the simulation scenario; (4) The main paintbrush and main canvas of the simulation scenario model, which exist in the memory of the simulation scenario model and are used to draw the simulation scenario, receive the background map pasted by the background paintbrush, and draw graphic images for the simulation object instances.

[0082] Load the bitmap in the simulation program and obtain the current paintbrush of the simulation program view. Initialize the memory paintbrush and memory canvas of the simulation program view according to the bitmap: Initialize the memory canvas of the simulation program view in bitmap format and use the memory canvas to load the bitmap; Initialize the memory paintbrush of the simulation program view in the format of the current paintbrush of the simulation program view and use the memory paintbrush to load the memory canvas.

[0083] Set the scaling size of the simulation scenario and set the positions of the vertical and horizontal scroll bars of the simulation program view according to the bitmap size and the scaling size.

[0084] Set a timer to update and draw the simulation scenario in the simulation program view regularly.

[0085] Triggered by the timer or by real-time monitoring of whether there is a human-computer interaction operation on the simulation program interface, update the current simulation scenario in the simulation program view, and paste the memory paintbrush of the simulation program view to the current paintbrush of the simulation program view.

[0086] Next, establish a simulation scenario model, which can include sub-modules such as a simulation scenario painting object class, a simulation scenario building object class, a simulation scenario map object class, a simulation scenario object class, etc., and set according to specific simulation requirements.

[0087] The simulation scenario drawing class sub-module is used to store and manage the background brush, background canvas, main brush, main canvas, bitmap, etc. of the simulation scenario model, and implement the drawing of the simulation scenario and simulation object instances.

[0088] The simulation scenario object class sub-module is used to describe and store the spatial data information of a single simulation scenario object instance.

[0089] The simulation scenario map class sub-module is used to store the spatial data of a series of simulation scenario objects, support simulation model query, and use the spatial object information in the simulation scenario.

[0090] The simulation scenario class sub-module is used to store and manage the simulation scenario drawing class and the simulation scenario map class, and implement the functions of simulation scenario drawing and transmission.

[0091] In one embodiment, the simulation scenario model includes:

[0092] The simulation scenario painting object class sub-module CScenePaint has variables such as the simulation scenario main brush "CDC*_pFrontDC", main canvas "CBitmap*_pFrontBitmap", background brush "CDC*_pBackDC", background canvas "CBitmap*_pBackBitmap", bitmap "BITMAP_bitMap", etc., and implements the drawing of the simulation scenario bitmap background and simulation object instances.

[0093] The simulation scenario building object class sub-module CBuilding has variables such as number "int_nID", name "string_strName", type "int_nType", top-left vertex pixel position "CPoint_pTopLeftPosition", width "int_nWidth", height "int_nHeight", etc., and is used to describe the information of a single graphic image object in the simulation scenario.

[0094] The simulation scenario map object class sub-module CSceneMap has an array variable of buildings "map<int,DMBuilding*>_mapBuildings", which is used to store the spatial position information of graphic image objects such as buildings, infrastructure, roads, etc. in the simulation scenario Figure 1 in this column.

[0095] The simulation scenario object class sub-module CScene describes the simulation scenario-related information, integrates the simulation scenario painting object class and the simulation scenario map class, implements the simulation scenario-related functions, and provides interfaces for simulation scenario drawing, simulation object instance drawing, querying buildings, places, etc. in the scenario for the simulation model framework.

[0096] The simulation object model class sub-module describes information such as the spatial position and state of the simulation object, and completes the designed task activities and interactions.

[0097] The simulation model framework object class sub-module integrally manages simulation object instances and simulation scenario object classes, obtains the memory brush of the program view from the simulation program framework, and passes the memory brush to the simulation scenario object class. When the state of the simulation object instance changes, it investigates the interface of the simulation scenario object class and updates and draws the simulation scenario. After updating and drawing the simulation scenario and the simulation object instance, the simulation scenario object class pastes and draws the latest simulation scenario onto the memory brush of the simulation program view.

[0098] After establishing the simulation program, start the simulation program to run, initialize the simulation scenario and simulation object instances, start the simulation execution, and visualize the simulation scenario animation.
