Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the special effects video generation methods of the present application may be applied.
As shown in fig. 1, devices 101, 102, 103, 104 and network 105 may be included in system architecture 100. The network 105 is the medium by which communication links are provided between the devices 101, 102, 103, 104. Network 105 may include various connection types, such as wired, wireless target communication links, or fiber optic cables, to name a few.
The devices 101, 102, 103, 104 may be hardware devices or software that support network connections to provide various network services. When the device is hardware, it can be a variety of electronic devices including, but not limited to, smart phones, tablets, laptop portable computers, desktop computers, servers, and the like. In this case, the hardware device may be implemented as a distributed device group including a plurality of devices, or may be implemented as a single device. When the device is software, it can be installed in the electronic devices listed above. At this time, as software, it may be implemented as a plurality of software or software modules for providing a distributed service, for example, or as a single software or software module. And is not particularly limited herein.
In practice, a device may provide a corresponding network service by installing a corresponding client application or server application. After the device has installed the client application, it may be embodied as a client in network communications. Accordingly, after the server application is installed, it may be embodied as a server in network communications.
As an example, in fig. 1, the devices 101, 102, 103 are embodied as terminals and the device 104 is embodied as a server. Specifically, the devices 101, 102, 103 may be clients actually installed with the target file, and 104 may be clients that provide the shredded special effects video for the target file.
In practice, because the special effect video generating method according to the current display content of the target file occupies little computing resources and has a relatively strong computing capability, and in order to consider the convenience of a user in playing the crushed special effect video when the target file is crushed subsequently, the special effect video generating method provided in the subsequent embodiments of the present application is generally executed by the devices 101, 102, and 103 in which the target file is installed, and accordingly, the special effect video generating device is generally also arranged in the devices 101, 102, and 103. In such a case, the exemplary system architecture 100 may also not include the device 104 and the network 105 embodied as servers.
However, it should be noted that, for example, in a case where the computing capabilities of the devices 101, 102, and 103 are insufficient, or a case where it is preferable to execute the special effect video generating operation at the device 104 embodied as a server (for example, when a service provider provides a special effect video crushing service for a user, and when the computing resources required for generating the special effect video crushing service are large, etc.), the device 104 may also complete the above-mentioned operations performed by the devices 101, 102, and 103 through the corresponding applications installed thereon, and then output the same results as those of the devices 101, 102, and 103. Especially, under the condition that a plurality of terminal devices with different computing capabilities exist at the same time, but the corresponding application judges that the device 104 has stronger computing capability and more computing resources are left, so that when the special effect video is generated more efficiently, the device 104 can execute the above operations, thereby appropriately reducing the computing pressure of the devices 101, 102 and 103, and correspondingly, the special effect video generating device can also be arranged in the device 104.
It should be understood that the number of networks and devices in fig. 1 is merely illustrative. There may be any number of networks and devices, as desired for an implementation.
Referring to fig. 2, fig. 2 is a flowchart of a special effect video generation according to an embodiment of the present application, where the process 200 includes the following steps:
In this embodiment, an execution subject of special effect video generation (for example, the devices 101, 102, 103 embodied as terminals shown in fig. 1) acquires current display content of a target file, and generates a corresponding Bitmap (Bitmap), which is also called a Raster map (Raster map) or a Bitmap, based on the current display content, which is an image represented by a Pixel array (Pixel-array/Dot-matrix lattice).
When the target file is closed, the currently displayed content may be a display icon and a corresponding file name of the target file, or may be the displayed content of a specific page in the target file, for example, a first page after the target file is opened, a tab page of the target file specified by the user, or the like.
It should be noted that the currently displayed content of the target file may be directly obtained by the execution main body from a local storage device, and the local storage device may be a data storage module, such as a server hard disk, disposed in the execution main body, in which case the currently displayed content of the target file is locally and quickly read.
In addition, when the execution subject performs special effect video generation for another device, the current display content of the target file may be acquired from a non-local storage device (for example, the device 104 shown in fig. 1), and the non-local storage device may also be any other electronic device configured to store data, for example, some user terminals, in which case the execution subject may acquire the current display content of the required target file by sending an acquisition command to the electronic device.
In practice, in order to better reflect the effect of the current display content of the target file, the size of the bitmap is preferably the same as the definition and size of the current display content, so that the subsequently generated special effect video content is opposite to the current display content to present a better effect.
In this embodiment, after the bitmap is obtained based on the step 201, a pixel value of each pixel point in the bitmap is stored in a collision data set (Crashdata), where the pixel value at least includes size information, and each component element in the collision data set records the size information and color information of the pixel point, and after the pixel value is stored in the collision data set, the size information in the change of the pixel value is correspondingly set to change with time in a preset time period.
The length of the preset time period generally corresponds to the deleting process of the target file, that is, the time when the desired pixel point starts to act is taken as the beginning, the time when the target file is deleted is taken as the end, and the corresponding preset time period is determined.
In some embodiments, the color information in the pixel value can be synchronously set to change along with the size in a preset time period, so as to further enrich the diversity of the special effect video.
Illustratively, when the expression of the collision data set is formed into a matrix, each data in the matrix of the collision data set corresponds to a value unit of a pixel point, a color value is provided in the value unit, and the x coordinate and the y coordinate of the pixel point in the bitmap form a matrix based on the value unit of each pixel point in the bitmap, so as to obtain the collision data set.
And 203, generating rendering images based on the collision data set, and generating the smashed special effect video of the target file according to a plurality of rendering images with continuous generation time.
In this embodiment, after the collision data set is obtained based on the step 202, since the size of the pixel point recorded in the collision data set changes with time in a preset time period, the corresponding image is generated by rendering according to the pixel point value recorded in the collision data set, the obtained images are arranged according to the generation time to obtain an image sequence, and a special-effect video for pulverization formed based on the change in the size of the pixel point is generated according to the image sequence.
The method for generating the special effect video comprises the steps of obtaining current display content of a target file, generating a bitmap of the current display content, storing pixel point values of pixel points in the bitmap into a collision data set, setting the size of the pixel points to change along with time within a preset time period, generating rendering images based on the collision data set, and generating a smashed special effect video of the target file according to a plurality of rendering images which are continuous in generation time. According to the embodiment, the smashing special effect can be generated based on the current display content in the target file, so that the smashing special effect video can be played when the target file is smashed in the follow-up process, a user can be helped to know the smashing state of the file, the interactivity of the file smashing process can be enhanced, and the user experience is enhanced.
In some embodiments, storing the values of the pixels in the bitmap into the collision dataset comprises: splitting the pixel points in the bitmap into a plurality of sub-pixel points with preset number; and respectively storing the pixel values of the sub-pixels into the collision data set.
Specifically, when the pixel points in the bitmap are stored in the collision data set, the pixel points in the bitmap can be further split into a plurality of sub-pixel points in a preset number, the shape of each sub-pixel point can be determined to be a circle corresponding to the pixel point, the sub-pixel points can also be determined to be a diamond shape, a triangle shape and the like according to actual requirements, and further pixel point values of all the sub-pixel points are stored in the collision data set respectively, so that the special effect fine granularity in the special effect video is promoted to be smashed.
In some embodiments, setting that the size of the pixel point changes with time within a preset time period includes: and in response to the fact that at least one pixel point dereferencing of the historical pixel point exists in the collision data set when the pixel point dereferencing is stored, taking the size change ending time of the historical pixel point as the size change starting time of the pixel point dereferencing.
Specifically, when the pixel value of the pixel is stored in the collision data set, the pixel value of the historical pixel which is stored in history already exists in the just-collided data set, the time of ending the change of the size of the historical pixel value along with the change of time is obtained, the ending time is used as the starting time of the change of the size of the pixel value stored at this time, the change of the size of the pixel value stored at this time is continued when the change of the size of the historical pixel is finished, and therefore the dynamic special effect is achieved.
In some embodiments, taking the size change ending time of the history pixel point as the size change starting time of the value of the pixel point includes: and taking the change ending time of the pixel point value of the historical pixel point with the shortest time from the size change ending time to the pixel point value as the size change starting time of the pixel point value.
Specifically, the time of storing the pixel values of the historical pixels into the collision data set is judged, and the time of finishing the change of the size of the historical pixel value with the time after the latest storage time is taken as the initial time of the change of the size of the currently stored pixel value, so that the continuity of each part in the special effect is further improved.
In some embodiments, the method for generating a special effect video further includes: and updating the preset time period in response to the fact that the number of the pixel points which change in size in the same preset time period in the collision data set meets the preset requirement.
Specifically, when the number of the pixels which change in size based on the same preset time period and are set in the collision data set meets the preset requirement, the preset time period is updated, and the size of the subsequent pixels is correspondingly set in the updated preset time period, so that the size of the pixels is set in a gradient manner, and more types of special effects are formed.
In some embodiments, storing a value of a pixel point in the bitmap into a collision data set, and setting a size of the pixel point to change with time within a preset time period, includes: storing the pixel value of the pixel point in the bitmap into a collision data set, and acquiring the size of the pixel point; and determining the change speed according to the size, and setting the size of the pixel point in a preset time period to change along with time according to the change speed.
Specifically, when the pixel value of the pixel in the bitmap is stored in the collision data set, the size of the pixel is obtained, the corresponding change speed is determined according to the size, the size of the pixel is changed along with the time according to the change speed in a preset time period, the special effect adaptive to the resolution of the current display content is generated, and the visual effect is improved.
Further, on the basis of any of the above embodiments, in order to fully enable the special effect video obtained according to the special effect video generation method to function, the special effect video can also function in a file shredding scene according to the following steps:
in response to receiving a crushing instruction sent aiming at a target file, file crushing operation is carried out on the target file, and a special crushing effect video corresponding to the target file is played; wherein the shredded special effects video is generated by a special effects video generation method as provided in fig. 2.
On this basis, referring to fig. 3, a flow 300 of an embodiment of a special effect video playing method is shown, which specifically includes:
In this embodiment, a device actually installed with a target file is generally used as an execution main body of the special effect video playing method (for example, the devices 101, 102, and 103 shown in fig. 1 and embodied as terminals), and after receiving a shredding instruction sent for the target file, the execution main body may perform corresponding playing from acquiring a locally generated shredded special effect video in advance, or may acquire a shredded special effect video of a required target file by sending an acquisition command to another device for generating the shredded special effect video.
In this embodiment, after the shredding instruction sent by the target file starts to be executed, the interface of the device that stores the target file jumps to the display interface where the start identifier of the target file is located, which may be, for example, a desktop, an application menu, and the like where the start identifier of the target file is located, and the transparency of the start identifier in the display interface is reduced.
In some embodiments, if it is explicitly specified that the target of the shredding is partial data in the target file in the shredding instruction sent for the target file, it may be correspondingly determined that the start identifier is the start identifier for calling the partial data in the target file, and the interface is correspondingly jumped to the interface in which the start identifier of the partial data is recorded in the target file.
In some embodiments, in order to better present the display effect of the special effect video, the transparency of all the activation flags included in the display interface may be further turned down.
And 303, playing the smashed special-effect video corresponding to the target file on a lower-layer interface of a display interface where the starting identifier of the target file is located.
In this embodiment, a special effect video corresponding to the target file is played on a lower interface of a display interface where the start identifier is located, so that the target file and the corresponding special effect video are simultaneously presented on the device.
The special-effect video playing method provided by the embodiment can synchronously play the crushed special-effect video corresponding to the target file when the target file is deleted, so that a user can be helped to know the crushing state of the file, the interactivity of the file crushing process can be enhanced, and the user experience is enhanced.
In some embodiments, the method further comprises: updating the current display content according to the deletion progress of the target file; obtaining an updated and smashed special effect video based on the updated current display content; and playing the smashed special-effect video corresponding to the target file, wherein the steps of: and playing the updated special-effect video with the smashing effect.
Specifically, when the execution main body executes the shredding operation of the target file and plays the shredded special effect video, the current display content may be further updated according to the deletion progress of the target file, for example, when the shredding progress reaches 50%, the display content may be clipped to 50% of the original image, the updated current display content is obtained, and the updated current display content is fed back, so that the execution main body of the special effect video generation method updates the shredded special effect video according to the updated current display content, and the shredding progress is better fed back to the shredded special effect video, so as to generate the shredded special effect video with higher dynamic reference value.
In order to deepen understanding, the application also provides a specific implementation scheme by combining a specific application scene:
1) in the application scenario, the main body of the special effect video generation method acquires the current display content (a simple line of a house) of the target file, as shown in fig. 4-1, and generates a bitmap of the current display content.
2) And storing the pixel value of the pixel point at least comprising the size information in the bitmap into a collision data set, and setting the size of the pixel point to be increased by 0.5 time (namely the size x and y coordinates of the pixel point are amplified by 0.5 time per second) within a preset time period along with the time every 1 second.
3) Generating a rendering image based on the collision data set, and generating a special effect smashing video of the target file according to a plurality of rendering images which are generated continuously in time, wherein a rendering image effect schematic diagram for generating the special effect smashing video can refer to fig. 4-2.
In the application scene, an execution main body of the special effect video generation method can generate a corresponding bitmap according to the current display content of the target file, and after pixel values of pixels in the bitmap are stored in the collision data set, elements in the collision data set are controlled to change along with time, namely, the pixels in the bitmap gradually change along with the time, so that a special effect that the pixels in the bitmap gradually expand is generated, the special effect that the target file is gradually crushed is simulated, and the final crushed special effect video is obtained, so that the crushed special effect video is played when the target file is crushed subsequently, a user can be helped to know the crushing state of the file, the interactivity of the file crushing process can be enhanced, and the user experience is enhanced.
