Therefore, the drawing method based on the fractal Brownian motion model is provided to solve the technical problems that the existing intelligent drawing tool requires high drawing foundation, complicated drawing operation and low drawing interestingness.
The first embodiment is as follows:

Generally speaking, the drawing device based on the fractal brownian motion model can be a computer, a mobile phone, a tablet, an electronic whiteboard and other terminal devices.
The following description will be given taking a drawing device based on a fractal brownian motion model as an example of a device for executing a drawing method based on a fractal brownian motion model. Referring to fig. 1, the drawing method based on the fractal brownian motion model specifically includes:
s110, responding to a first touch operation of a user, and determining a basic graph selected by the user, wherein the basic graph is preset for the user to select.
Illustratively, when drawing, a user draws pictures through a human-computer interaction interface provided by a drawing device based on a fractal Brownian motion model. Taking a tablet personal computer as an example, drawing a picture through a screen of the tablet personal computer, and displaying the picture drawn by a user on a drawing area corresponding to the screen of the tablet personal computer in real time.
Furthermore, before drawing, various different color or monochrome basic graphs can be stored in advance on the tablet personal computer, the basic graphs are placed in the basic graph database, and the basic graphs are used for being selected by a user to draw. The basic graphics can be basic graphics of various styles downloaded via an forgiveness network, or basic graphics obtained by converting a photo into different forms (sketching, painting). Converting the real object of the photo into the painting works with different forms such as sketch, oil painting and the like is a mature technology in the prior art, and is not described herein any more. In addition, the basic graph can also be a picture drawn by the user and stored in the tablet computer. There are many ways to obtain the basic graphics, and the embodiments of the present application are not limited to this example, and are not described herein in detail. And when the user uses the tablet personal computer to draw pictures, basic graphs in the basic graph database can be added and deleted according to actual needs.
And then, when drawing a picture, opening a basic graph database by clicking a corresponding option on a screen of the tablet computer, displaying basic graphs in the basic graph database on the screen in a graph list mode, displaying each graph on the screen in a thumbnail, selecting a required basic graph by a user by clicking the position of a corresponding thumbnail on the screen, defining the clicking operation as a first touch operation, and finishing the selection of the basic graph by the first touch operation. And the selected basic graph is used for drawing on the drawing area subsequently.
It should be noted that, in drawing, a user may need a plurality of different basic graphics, and each time the user selects a basic graphic, drawing operations on a drawing area are performed by the user with the corresponding basic graphic. When the user needs to use other basic graphs, the user can click the basic graph database option on the screen of the tablet computer, open the basic graph database and select the basic graphs again. After the basic graph is reselected, drawing operation on the drawing area is performed by the reselected basic graph.
And S120, responding to a second touch operation of a user in a drawing area, generating the basic graph at a corresponding position of the drawing area, and randomly selecting a generating direction according to the fractal Brownian motion model.
Specifically, after the basic graph is selected, the corresponding position on the drawing area can be clicked to draw, and it can be understood that the position clicked by the corresponding user is the placement position of the basic graph in the drawing area. Defining the click operation as a second touch operation, referring to fig. 2, selecting a piece of tree leaves as a basic graph, and clicking a corresponding position on a drawing area to finally form a branch picture consisting of a plurality of tree leaves, thereby completing drawing of the picture.
In addition, in the drawing process, the growing positions of the leaves are determined according to the clicking positions of the users, and the different sizes of the leaves are determined according to the time length of the users clicking the screen. And the growth direction of the leaves is randomly generated according to the fractal Brownian motion model.
The fractal Brown motion model is an ideal irregular diffusion and fractal random walking basic model, and the curves of the fractal Brown motion model have certain self-similarity locally and integrally, so that the basic graph generated each time has certain self-similarity in the generation direction. As shown in fig. 2, by clicking the screen along the position of the branch of the "branch", the self-similarity basic graph growing in each random direction is finally generated by utilizing the self-similarity of the fractal brownian motion model.
Determining the generation position of the basic graph according to the user click position may refer to a basic graph generation flow, as shown in fig. 3, the basic graph generation flow includes:
s1201, responding to a second touch operation of a user in a drawing area, and determining a first click position corresponding to the second touch operation on the drawing area;
and S1202, generating the basic graph by taking the first point-by-position as a generation starting point of the basic graph.
Specifically, after a user selects a certain basic graph, the user clicks the placement position of the selected basic graph according to the drawing position provided by the screen of the tablet computer, and the position of the basic graph on the drawing area can be selected by using an input device such as a mouse and the like corresponding to other drawing devices such as a computer. When the user clicks a certain position of the drawing area, the tablet computer records the position according to the clicking operation of the user and records the plane coordinate of the position on the drawing area. And defining the position as a first click position, and displaying a corresponding basic graph at the corresponding coordinate of the drawing area according to the plane coordinate of the first click position on the drawing area so as to finish the generation of the basic graph.
More specifically, a basic graph size determination flow chart is provided, and referring to fig. 4, the basic graph size determination flow includes:
s1203, responding to a second touch operation of the user in the drawing area, and determining a click-press duration corresponding to the second touch operation;
s1204, determining the size of the basic graph on the drawing area according to the point-by-point duration.
Specifically, before drawing, the related drawing application program of the tablet computer presets the construction levels of the basic graph corresponding to different points according to the time length, and different construction levels represent different display sizes of the basic graph on the drawing area. According to the embodiment of the application, the size of the corresponding basic graph is determined according to the click-to-press duration of the second touch operation. It can be understood that the longer the time that the user presses the screen by the second touch operation point, the larger the display size of the basic graphic on the drawing area. And when the point-press time length reaches a certain time length threshold value, displaying the basic graph in the maximum size allowed by the drawing area. And then, determining a corresponding construction level according to the point-press time length of the screen by the user in real time, and generating a basic graph with a corresponding size on the drawing area based on the construction level. For example, a user clicks on the screen for 0.5 second to build a 2-layer growth pattern, and clicks on the screen for 1 second to build a 4-layer growth pattern. The higher the build level of the underlying pattern growth pattern, the larger its size is. It should be noted that, when the user clicks the screen to generate the basic graph, the second touch operation corresponding to the user immediately starts to record the click duration of the second touch operation, at this time, a corresponding basic graph is generated at a corresponding position of the drawing area on the screen in real time according to the real-time click duration of the user, the basic graph gradually changes from small to large according to the continuation of the click operation, and when the click operation of the user is finished, the basic graph stops increasing, so that the user can intuitively determine the size of the set basic graph. As shown in FIG. 2, the leaves with different sizes are generated by clicking different time lengths of the screen, so that the composition of the tree branches is more reasonable, and the quality of the finally generated pictorial representation is better.
The basic graph selected by the user is determined in real time by presetting the basic graph for the user to select, and the corresponding basic graph is generated at the corresponding position of the drawing area according to the touch operation of the user in the drawing area. By adopting the technical means, the complicated operation of a user in the drawing process can be simplified, and the drawing of the drawing work can be quickly finished by selecting the basic graph and determining the placement position of the basic graph, so that the drawing learning and operating cost is reduced. In addition, the basic graph of the embodiment of the application randomly selects the generating direction according to the fractal Brownian motion model and is drawn on the drawing area, so that the self-similarity of each basic graph can be guaranteed, and the interestingness of drawing is increased.
Example two:
on the basis of the foregoing embodiment, fig. 5 is a flowchart of another drawing method based on a fractal brownian motion model according to the second embodiment of the present application. Referring to fig. 5, the drawing method based on the fractal brownian motion model provided in this embodiment specifically includes:
s210, responding to a first touch operation of a user, determining a basic graph selected by the user, wherein the basic graph is preset for the user to select;
s220, responding to a second touch operation of a user in a drawing area, generating the basic graph at a corresponding position of the drawing area, and randomly selecting a generating direction according to a fractal Brownian motion model;
s230, responding to a third touch operation of the user, selecting the corresponding basic graph, and adjusting the direction of the corresponding basic graph on the drawing area according to the sliding direction of the third touch operation.
According to the method and the device, after the basic graph is drawn, the direction of each basic graph on the drawing area is adjusted by responding to the relevant touch operation of a user in real time. The touch operation is defined as a third touch operation, and the third touch operation can be triggered by pressing a drawing area corresponding to a basic graph for a long time, so as to distinguish the previous second touch operation. When a user presses a certain basic graph on the drawing area for a long time to reach a set time threshold, the direction adjustment operation of the basic graph is triggered, and at the moment, the direction of the selected basic graph is correspondingly adjusted according to the sliding direction of the third touch operation of the user.
Specifically, a second click position of the third touch operation in the drawing area is determined, and the corresponding basic graph in the set distance range is selected by taking the second click position as a center. When the user adjusts the direction of the corresponding basic graphic, in order to clarify the basic graphic selected by the user, the basic graphic selected by the user needs to be determined according to the coordinates of the second point of the user on the drawing area. By taking the coordinate as a center, and taking the center point of the basic graph on the drawing area as a set distance range of the center, the basic graph which is currently selected by the user for direction adjustment is considered to be the basic graph. The central point of the basic graph can determine a starting point of basic graph generation according to the previous second touch operation as the central point of the basic graph.
And when the direction of the basic graph is adjusted, the tablet personal computer responds to the sliding of the third touch operation in real time to adjust the direction of the corresponding basic graph on the drawing area of the screen in real time according to the sliding direction of the third touch operation, and the process is continuously displayed on the screen in real time, so that a user can determine the final direction of the basic graph according to the feedback of the screen, and the direction adjustment effect of the basic graph is optimized.
Through providing basic figure direction adjustment operation in this application embodiment to the user carries out the direction adjustment to the basic figure that has drawn in real time, ensures that the composition of picture that the picture was drawn is more exquisite, further promotes the interest of drawing.
Example three:
on the basis of the foregoing embodiment, fig. 6 is a flowchart of another drawing method based on a fractal brownian motion model according to a third embodiment of the present application. Referring to fig. 6, the drawing method based on the fractal brownian motion model provided in this embodiment specifically includes:
s310, responding to a first touch operation of a user, determining a basic graph selected by the user, wherein the basic graph is preset for the user to select;
s320, responding to a second touch operation of a user in a drawing area, generating the basic graph at a corresponding position of the drawing area, and randomly selecting a generating direction according to a fractal Brownian motion model;
s330, responding to a fourth touch operation of the user, and deleting the corresponding basic graph from the drawing area.
After the basic graph is drawn, deleting operation corresponding to the generated basic graph on the screen drawing area is carried out by responding to the fourth touch operation of the user. And selecting the corresponding basic graph according to the fourth touch operation of the user, deleting the basic graph, and not displaying the basic graph on the drawing area of the screen. The fourth touch operation may be triggered by double-clicking the drawing area corresponding to the basic graph, so as to distinguish the previous second and third touch operations. When a user double-clicks a certain basic graph on the drawing area, the deleting display operation of the basic graph is triggered, and at the moment, the selected basic graph is correspondingly deleted according to the fourth touch operation of the user.
Similarly, the double-click position of the fourth touch operation in the drawing area is determined, and the corresponding basic graph in the set distance range is selected by taking the double-click position as the center. It should be noted that, when the user deletes the corresponding basic graphic, in order to clarify the basic graphic selected by the user, the basic graphic selected by the user needs to be determined according to the coordinates of the user double-click on the drawing area. And by taking the coordinate as a center and taking the center point of the basic graph on the drawing area as a set distance range of the center, the basic graph which is selected by the user for deletion currently is considered. The central point of the basic graph can determine a starting point of basic graph generation according to the previous second touch operation as the central point of the basic graph.
According to the embodiment of the application, the basic graph is deleted and the display operation is performed, so that a user can delete the drawn basic graph in real time, the composition of the picture is more exquisite, and the interestingness of drawing is further improved.
It should be noted that, in the first, second, third, and fourth touch operations in the first, second, and third embodiments, a plurality of different input modes may be used according to actual needs and different use scenarios, and the specific input mode in the embodiment of the present application is not limited to be fixed, and is not described herein again.
