Detailed Description
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The method aims to solve the technical problems that scene dissolving switching is performed in a radial change mode in the existing three-dimensional game scene switching, the dissolving effect of the scene switching is poor, and the scene switching efficiency of the dissolving effect is influenced. The present embodiment provides a scene switching method, as shown in fig. 1, the method includes:
101. and acquiring a reference central point configured in the first scene and information of each element in the first scene.
The first scene can be a current scene page of the three-dimensional game, and the first scene needs to be switched to another scene page. The reference center point in this embodiment may be used to calculate height field data corresponding to the current scene page. In each scene, a reference center point may be configured. The reference center point of the configuration may not necessarily be located at the center of the scene page, but may be regarded as a center point used in calculation, and the subsequent height field calculation will be based on the reference center point for performing the mapping calculation. After finding the position corresponding to the reference center point, the value is recorded, which contains information in three-dimensional space, such as x, y, z position information on three-dimensional coordinate axes.
The element information in the first scene may include content elements in the scene page and layout conditions of the content elements in the scene page, such as text, pictures, hyperlinks, backgrounds, character shadings, tables and other content elements in the scene page, and distribution positions, shapes, sizes and the like of the content elements.
The execution main body of the embodiment may be a device or an apparatus for scene switching, and may be configured on a client side (e.g., a terminal side such as a smart phone, a personal computer, a tablet computer, etc.), and may be used for scene switching processing of a dissolving effect when a three-dimensional game page on the client side is displayed. The dissolving effect of scene switching can be improved, and the scene switching efficiency of the dissolving effect cannot be influenced.
102. And calculating height field data corresponding to the first scene according to the reference central point and each element information in the first scene.
The embodiment provides a scene switching scheme of a dissolving effect based on a height field, and can realize the effect of gradually dissolving in a hierarchical manner at a relatively balanced rate according to different models. Therefore, the height field data corresponding to the current scene page needs to be accurately calculated. For example, based on the position of the reference center point, height field data of each element with the reference center point is calculated. By the method, the height field data corresponding to the current scene page can be accurately calculated based on a reasonable reference central point by combining the content elements in the scene page and the layout condition of the content elements in the scene page.
The height field of the invention corresponds to a three-dimensional game scene, and the three-dimensional A scene is switched to the three-dimensional B scene through three-dimensional height field data, so that the game scene switching enables the dissolving effect to be more three-dimensional.
103. And carrying out random disturbance processing on the height field data.
For the embodiment, after the height field data of the current scene is obtained by calculation, the generated height field data is compared regularly, and more noise, disturbance and the like are required for achieving scene switching of the dissolving effect, so that the calculated height field data of the current scene is further subjected to random disturbance processing, and the effect of dissolving and switching of the subsequent scene can be improved.
104. And based on the height field data after the disturbance processing, performing scene dissolving rendering processing by taking the contour lines as scanning lines, so that the first scene is switched to the second scene.
The second scene may be another scene page to which the current scene page needs to be switched. The contour lines can be regarded as lines connected by points of the same height in the height field data. The height of the contour may vary with the scan direction.
For example, when a scene a of a three-dimensional game needs to be switched to a scene B with a dissolving effect, height field data corresponding to the scene a can be calculated according to a reference central point and each element information in the scene a; and then carrying out random disturbance treatment on the height field data, further creating a corresponding height field according to the height field data subjected to disturbance treatment, and adding a contour line after the height field is created. The method is characterized in that the positions of contour lines are changed along with the height change of the contour lines, so that the scanning effect of scanning lines is generated, the contour lines are used as separation lines for dynamic scanning to achieve an effect similar to a deep solution, and the contour lines are introduced and used as the scanning separation reason. The problem of the dissolving speed caused by the height difference can be solved to a great extent after the contour lines are used, so that the dissolving effect of scene switching can be improved while the scene switching efficiency of the dissolving effect is ensured. When the contour lines are used as scanning lines to perform rendering processing of scene dissolution, the contour lines are used as alternative separation lines to convert pixels in the scene A at the position in the height field into pixels in the scene B, and then rendering processing effect of scene dissolution switching is achieved.
Compared with the conventional scene dissolving switching in a radial variation mode, the scene switching method provided by the embodiment provides a scene dissolving switching scheme based on a height field, and can realize the effect of gradually dissolving in a hierarchical manner at a relatively balanced rate according to different models. Specifically, when the scenes of the three-dimensional game are switched, in the embodiment, first, height field data corresponding to a first scene can be calculated according to a reference center point configured in the first scene and information of each element in the first scene; then, carrying out random disturbance processing on the height field data; and finally, based on the height field data after disturbance processing, rendering processing of scene dissolution is carried out by taking the contour lines as scanning lines, so that the first scene is switched to the second scene, for example, the scanning direction of the scanning lines is the height descending or ascending direction of the contour lines, and the like, so that the effect of scene dissolution switching is gradually realized in a hierarchical manner at a relatively balanced speed, the dissolution effect of scene switching can be improved, and the scene switching efficiency of the dissolution effect cannot be influenced.
Further, as a refinement and an extension of the specific implementation of the foregoing embodiment, in order to fully describe the implementation of this embodiment, this embodiment further provides another scene switching method, as shown in fig. 2, where the method includes:
201. element distribution information in a first scene is obtained.
The element distribution information in the first scene may include distribution conditions of content elements, such as distribution positions, shapes, sizes, and the like of content elements in a scene page, such as characters, pictures, hyperlinks, backgrounds, character shadings, tables, and the like.
202. And configuring a reference central point in the first scene according to the obtained element distribution information.
Since the distribution condition of the content elements in the scene page is determined according to the layout requirement of the three-dimensional game content set by the user, the element distribution information in different scene pages may have various forms. In order to find the position of the reference point (i.e., the reference center point) corresponding to the height field in each scene page, in this embodiment, the most suitable reference center point may be configured in the scene according to the element distribution information in the current scene page, so as to subsequently improve the accuracy and efficiency of the calculation of the height field data corresponding to the scene.
For example, the center point position with respect to the respective content elements in the current scene page is configured in the current scene page in accordance with the distribution position, shape, size, and the like of the content elements in the current scene page. If the pixel point coordinates of the content elements are obtained, then the central point position relative to the content elements is calculated in a world coordinate system based on the pixel point coordinates and is used as a reference central point.
203. And acquiring a reference central point configured in the first scene and information of each element in the first scene.
When the first scene needs to be switched to the second scene with the dissolving effect, the embodiment may obtain the reference center point configured in the first scene and information of each element in the first scene, so as to calculate height field data corresponding to the first scene by a height field method according to the world coordinates used during rendering, and may specifically perform the processes shown in steps 204 to 205.
204. And obtaining each pixel point of each element information in the first scene.
205. And calculating height field data corresponding to the first scene according to the pixel points of the element information and the reference central point configured in the first scene.
In this embodiment, according to the pixel point position and the reference center point position of each content element in the current scene page, the element layout condition in the current scene page may be referred to, and height field data corresponding to the current scene page may be accurately calculated, so as to ensure that subsequent accurate scene dissolving switching may be performed.
When the height field data is specifically calculated, optionally, step 205 may specifically include: firstly, according to the position of a pixel point of element information, acquiring a vertex of the element information in a world coordinate system; and then, calculating the position distances between the top points and the reference center point respectively in a world coordinate system by using a height field algorithm, and taking the position distances as height field data corresponding to the first scene.
For example, when a scene is converted, the world coordinates are mainly calculated in the rendering stage, because any model of the scene is combined in a set of vertex information matrixes, and when the world coordinate system is used, the positions of the vertex information in the matrixes are uniform and consistent when the height field data is calculated. In this case, the height field data of each point and the center point is calculated using a distance height field algorithm based on the position of the reference center point. The height field function may be as shown in equation one.
In the above formula I, x represents the abscissa of the world coordinate system, and y1Representing the ordinate of the world coordinate system. a is1And a2Represents a constant, abs (x) represents the absolute value of x. With a1＝1.8，a2The height field function is shown in fig. 3, for example 2. As can be seen from fig. 3, the height field function generated at this time is compared with the rule, and the scene dissolving switch requires more noise and disturbance, so some changes need to be made to the height field function of this rule, i.e., the process shown in step 206 is performed.
206. And (4) randomly disturbing the value of the height field in frequency and amplitude.
For the embodiment, the effect of subsequent scene dissolving switching can be improved by performing random disturbance processing on the frequency and the amplitude of the value of the height field which is relatively regular. In this embodiment, there may be a plurality of alternative ways to perform the disturbance processing on the height field data. As an exemplary option, step 206 may specifically include: firstly, creating disturbance field data according to the frequency and amplitude of the value of the height field; then overlapping the disturbance field data and the height field data; and carrying out noise disturbance processing on the height field data after the superposition processing to obtain the height field data after the disturbance processing. In this way, the values of the height field can be well disturbed randomly in frequency and amplitude.
For example, from the frequency and amplitude of the value of the height field, the perturbing field data is created with the contents of equation two:
y2＝sin(x·b1)·b2formula two
In the second formula, x represents the abscissa of the world coordinate system, and y2Representing the ordinate of the world coordinate system. b1And b2Representing a constant. With b1＝2.1，b2For example, fig. 4 shows a function image generated by 0.3. And in combination with the height field function as shown in FIG. 3, for y1And y2And (3) performing superposition operation, namely superposing the height field and the disturbance field to form a graph as shown in fig. 5, and performing preliminary disturbance processing on the originally regular function image to obtain an irregular function image. Further, in order to achieve a better random disturbance effect, a function image as shown in fig. 6 can be formed by operating sound or other forms of disturbance based on the function as shown in fig. 5. As can be seen from the function image shown in fig. 6, the random disturbance processing of frequency and amplitude can be effectively performed on the value of the height field by the optional method, so that the subsequent scene dissolving and switching effect can be ensured.
207. And based on the height field data after the disturbance processing, performing scene dissolving rendering processing by taking the contour lines as scanning lines, so that the first scene is switched to the second scene. The first scene and the second scene are game scenes with three-dimensional data.
Optionally, step 207 may specifically include: traversing contour lines of all heights in the height field according to the scanning direction, and taking the contour line of the latest height as a separation line each time; then obtaining the separation position of the separation line in the height field data; and finally, converting the pixel at the corresponding position in the first scene into the pixel at the corresponding position in the second scene according to the separation position.
For example, after the calculation of the height field is completed as shown in fig. 6, as shown in fig. 7, a contour h may be added, and as the contour h goes down (corresponding to the scanning process of the scanning line), the contour h with the latest height is used as a separation line each time, so as to make an effect similar to a deep solution. Specifically, the separation position 1 of the current separation line in the height field data can be obtained; according to the partition position 1, the pixel of the corresponding position in the scene a is converted into the pixel of the corresponding position in the scene B. Then, along with the descending of the contour line h, the separation position 2 of the separation line in the height field data at the new height is obtained; according to the partition position 2, the pixel of the corresponding position in the scene a is converted into the pixel of the corresponding position in the scene B. Then, along with the descending of the contour line h again, the separation position 3 of the separation line in the height field data at the latest height is obtained; according to the partition position 3, the pixel of the corresponding position in the scene a is converted into the pixel of the corresponding position in the scene B. By analogy, the pixels in the scene a are converted into the pixels in the scene B one by one according to the scanning direction (the descending direction of the contour line h in fig. 7), and further the effect of dissolving and switching the scene a to the scene B is achieved. By the scene switching mode of the dissolving effect, the dissolving effect of scene switching can be improved by gradually dissolving according to different models and relatively balanced speed levels, and the scene switching efficiency of the dissolving effect cannot be influenced.
Further optionally, in order to save resource invocation of the system at the scene change, before step 207, the method may further include: detecting whether the first scene and the second scene have the same content or not; if the contents of the first scene and the second scene are the same, rendering processing of scene dissolving can be cancelled; correspondingly, step 207 may specifically include: if the contents of the first scene and the second scene are different, rendering processing of scene dissolution can be performed by taking the contour lines as scanning lines based on the height field data after disturbance processing, so that the first scene is switched to the second scene. For example, if the contents of the scene a and the scene B are the same, the scene switching with the dissolving effect may not be needed, so as to save the resource call of the system during the scene switching, and if the contents of the scene a and the scene B are different, the scene dissolving switching process of the method of the present embodiment may be executed. It should be noted that, according to specific practical application requirements, in practical applications, the scene dissolving and switching process of the method of the present embodiment may be set to be executed when the contents of the scene a and the scene B are the same, so as to meet certain requirements.
At present, in the three-dimensional game scene switching, the scene switching of the dissolving effect mainly takes MASK, random noise field and radial variation methods as main methods. The actual effects are monotonous and rough, the dissolution is mainly carried out by using points or shapes and a random noise method, the direction sense is avoided, and the effect is disordered; the radial mode is used for dissolution, the directivity is too strong, the visual monotonous effect is poor, and the noise distortion added for ensuring the dissolution effect to be natural has great change and difference on the effect per se besides the problem of efficiency; the method used as a MASK map scans in all directions, so that the effect of circular diffusion or contraction is difficult to make, or the dissolution form is limited, and the efficiency and the controllability of the program of the MASK are not high. To solve these problems in the prior art, the present embodiment provides a dissolution effect based on a height field. The effect of gradually dissolving in different layers at a relatively balanced rate according to different models is realized. Not only the controllability of the program is high, but also the dissolution effect is controllable by parameters; and the efficiency is high, the effect is good, and the natural layered dissolving and replacing effect can be achieved.
