In addition, the memory 120 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one magnetic disk storage device, a flash memory device, or other volatile solid-state memory device.

Optionally, the touch panel 131 can include two parts, a touch detection device and a touch controller. Among them, the touch detection device detects the touch position of the user and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, and converts it into touch coordinates and sends it to the processor 180, and can also receive the commands from the processor 180 and execute them.

Although in the above description, the touch panel 131 and the display panel 141 are realized as two independent components to realize the input and output functions of the computer device, in some embodiments, the touch panel 131 and the display panel 141 can be integrated to realize the input and output functions of the computer device.

Specifically, the light sensor can include an ambient light sensor to adjust the brightness of the display panel 141 according to the brightness of ambient light, and a proximity sensor to turn off the display panel 141 and / or the backlight when the computer device is moved close to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude and direction of the acceleration in each direction (typically three axes), the magnitude and direction of the gravity when the device is static, and can be used for identifying the device posture application (such as landscape / portrait screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, knock), and the like. As for other sensors that can also be configured on the computer device, such as a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, and the like, will not be described here.

[0048] The audio circuit 160, the speaker 161, and the microphone 162 can provide an audio interface between the user and the computer device. The audio circuit 160 can convert the received audio data into an electrical signal, transmit it to the speaker 161, and convert it into a sound signal output by the speaker 161. On the other hand, the microphone 162 converts the collected sound signal into an electrical signal, which is received by the audio circuit 160 and converted into audio data. After being processed by the processor 180, the audio data is transmitted to another device via the communication unit 110, or output to the storage 120 for further processing.

[0049] The camera unit 170 is used to implement the shooting function and collect corresponding shooting images, such as still images, dynamic images, or videos. In actual application, the camera unit 170 can include at least one camera, and the number and type of the camera are not limited in the present application, such as but not limited to a long-focus camera, a short-focus camera, an infrared camera, or other cameras with shooting functions. The specific structure of the camera will not be described here.

[0050] The processor 180 is the control center of the computer device, which connects all parts of the computer device through various interfaces and lines, executes the software programs and / or modules stored in the storage 120, and calls the data stored in the storage 120, to perform various functions and process data of the computer device, thereby monitoring the computer device as a whole.

[0053] Next, an embodiment of a virtual engine adapted by the present application is introduced. Please refer to Figure 2 is a possible structure diagram of a virtual engine provided by an embodiment of the present application. As Figure 2 shown, the virtual engine 200 is a virtual engine in a computer device, which can include an optical flow component 201 and a particle processing component 202. It can be understood that Figure 2 the component structure shown in the figure does not constitute a limitation on the virtual engine 200, and more or fewer functional components than shown can be included according to actual needs, which is not limited by the present application. Among them:

[0054] The virtual engine 200 of the present application is mainly used to add or realize corresponding collision effects for the object to be collided. In actual application, the virtual engine 200 can be a pixel particle TouchDesigner interactive engine, or other software engines for realizing / adding collision effects, etc., which is not limited by the present application.

[0055] The optical flow component 201 is mainly used for optical flow conversion of image data of the object to be collided, to convert into a corresponding optical flow image. The optical flow image is used to represent the motion information of the object to be collided, so as to facilitate subsequent generation of corresponding forces on the particle system based on the motion information, to realize corresponding collision effects. The optical flow component 201 can also transmit the optical flow image of the object to be collided to the particle processing component 202 for processing. Please refer to Figure 3 is a possible image transmission diagram based on a virtual engine provided by an embodiment of the present application. As Figure 3 shown, after obtaining the image data of the object to be collided, the virtual engine 200 can transmit the image data to the optical flow component 201 for processing, and then transmit the processed optical flow image to the particle processing component 202 for processing via the optical flow component 201.

[0056] Optical flow or optic flow, which is related to the present application, is a concept in the detection of object motion in a field of view. It is used to describe the motion of an observed target, surface or edge caused by motion relative to an observer. Optical flow is very useful in pattern recognition, computer vision and other image processing fields, and can be used for motion detection, object cutting, collision time and object expansion calculation, motion compensation coding, or stereoscopic measurement through object surfaces and edges, etc. without limitation.

[0057] The particlesGpu component 202 is mainly used to receive the optical flow image sent by the opticalFlow component 201, and to generate particle interaction based on the optical flow image and the particle system (such as particles in the particle system) to add corresponding collision effects to the object to be collided.

[0058] It should be noted that the opticalFlow component 201 and the particlesGpu component 202 shown in the present application are only example components in the virtual engine 200, and more or fewer functional components can be included according to actual conditions, which are not limited herein.

[0059] Based on the foregoing embodiments, the following describes a method embodiment applicable to the present application.

[0060] Please refer to Figure 4 is a flow diagram of a possible collision effect adding method provided by an embodiment of the present application. As Figure 4 shown, the method is applied to a computer device, and can be specifically applied to a virtual engine in the computer device. The method includes the following implementation steps:

[0061] S401, obtaining image data of an object to be collided.

[0062] The present application does not limit the implementation manner of obtaining image data, for example, the image data of the object to be collided can be obtained by shooting through a camera device, or the image data of the object to be collided can be received from other devices (such as terminal devices or servers) through a network.

[0063] In actual application, the present application can obtain the image data of the object to be collided by calling the opticalFlow component in the virtual engine (such as the TouchDesigner interactive engine), and the image data of the present application is usually two-dimensional image data.

[0064] Before calling the opticalFlow component, the present application can pre-configure corresponding working parameters of the opticalFlow component, which can be referred to as configuration parameters of the opticalFlow component. The configuration parameters of the opticalFlow component are mainly used to indicate or reflect the required motion force of the to-be-collided object in the particle system, and can be understood as the force that the to-be-collided object can generate in the particle system to a certain extent. In actual application, the configuration parameters of the opticalFlow component can include but are not limited to, for example, force field parameters, rigid body parameters or other custom parameters, etc.

[0065] S402, obtain collision parameters, the collision parameters are used to reflect the required collision effect in the current scene.

[0066] The present application does not limit the implementation manner of obtaining the collision parameters, for example, the present application can obtain the collision parameters by calling the particlesGpu component in the virtual engine (such as the TouchDesigner interactive engine). The collision parameters of the present application are mainly used to indicate or reflect the collision effect that is intended / required to be generated in the current scene. Different collision parameters can be set for different application scenarios, that is, the present application can set appropriate collision parameters in combination with the current application scenario (referred to as the current scene), so that the image data of the to-be-collided object is more obvious in the collision effect, which is not limited and described here.

[0067] Before calling the particlesGpu component, the present application also needs to pre-configure corresponding working parameters of the particlesGpu component, which can be referred to as configuration parameters of the particlesGpu component. The configuration parameters of the particlesGpu component are mainly used to indicate or reflect the required collision effect of the to-be-collided object in the particle system, which can include but are not limited to any one or a combination of more of the following: for example, model size, lens distance, particle drag strength, particle collision range, screen display information or other custom information, etc. Among them:

[0068] The model size is determined based on the image data of the to-be-collided object. In the implementation process, the particlesGpu component can generate a plane image according to the received image data, and use the screen image as the model of the to-be-collided object, that is, the model size that can be collided. The screen display information includes but is not limited to the size information (such as length and / or width) of the display screen and the resolution or other display screen information of the display screen. The lens distance refers to the distance between the virtual lens in the current scene and the to-be-collided object. The particle drag strength and the particle collision range are both parameters for limiting / regulating the particle collision effect.

[0069] In practical applications, the particlesGpu component can adjust the model size and lens distance according to the actual required output screen resolution. For example, when the resolution of the output display screen needs to be 1080p or 720p, the application can set different model sizes and lens distances in the program code according to the model size generated by the planar image, so as to adjust the shooting range of the lens. If the model size and lens distance are not adjusted, the to-be-collided object will be located at the edge of the lens shooting picture, and the effect picture formed after subsequent processing will not correctly correspond the to-be-collided object and the object in the lens picture, resulting in poor game experience for the player / guest. It can be seen that the application can set or adjust the corresponding component configuration parameters according to the display requirements of the picture.

[0070] The application also adjusts the particle dragging force and particle collision range according to the visual effect. For example, the high and low of the particle dragging force can control the collision effect of the to-be-collided object in the particle system, and the higher the particle dragging force, the higher the speed of the collided particle in the collision process. However, too high particle dragging force can easily cause the picture to become very chaotic and fancy during the collision process.

[0071] It can be understood that the collision range of the particle usually appears in a cubic square by default, and the planar collision model generated by the application based on the image data of the to-be-collided object (which is two-dimensional planar image data) lacks thickness data and is located at the center of the cubic square, resulting in that most of the particles cannot achieve the collision effect. Therefore, the application needs to change the collision range of the particle from a cubic square to a line, that is, the particle collision range of the application needs to be linear in shape, so that the state of the particle generation is also presented in a planar manner, which can make the central planar image data more intuitive to produce a collision relationship with the particle system. At the same time, since the particle generation has a length range setting, it usually needs to be manually adjusted, and the length of the linear particle generation will be stretched according to the lens distance in the program, which can better fill the picture and improve the display quality and effect of the picture.

[0072] In practical applications, the collision parameters of the application can include the configuration parameters of the opticalFlow component and the configuration parameters of the particlesGpu component. The configuration parameters of the opticalFlow component and the particlesGpu component can be referred to the related description in the foregoing embodiments, which will not be repeated here.

[0073] S403, based on the collision parameters and the image data of the to-be-collided object, adding a corresponding collision effect to the to-be-collided object.

[0074] The application can perform optical flow conversion on the image data of the to-be-collision object by calling the opticalFlow component in the virtual engine to obtain an optical flow image of the to-be-collision object. The implementation of optical flow conversion can be referred to the foregoing Figure 2 In the related introduction in the embodiments, details are not repeated here. After obtaining the optical flow image, the opticalFlow component can transmit the optical flow image to the particlesGpu component, so that the particlesGpu component can interact with the particle system. In the implementation process, the application can further call the particlesGpu component in the virtual engine to perform particle interaction on the optical flow image of the to-be-collision object based on the collision parameters, so as to add corresponding collision effects for the to-be-collision object in the particle system. The application does not limit the implementation of the foregoing particle interaction. For example, the application can add the collision effect of the to-be-collision object by using the particle system to make or add corresponding particles, so as to complete the addition of the collision effect of the to-be-collision object.

[0075] By implementing the embodiments of the application, the computer device obtains image data of a to-be-collision object; obtains collision parameters, the collision parameters being used to reflect a collision effect to be generated in a current scene; and adds a corresponding collision effect for the to-be-collision object based on the collision parameters and the image data of the to-be-collision object. It can be seen that the application can add a corresponding collision effect for the to-be-collision object based on the collision parameters and the image data of the to-be-collision object, which not only realizes convenient and rapid addition of the collision effect, but also saves terminal power consumption. At the same time, the problems of complicated operation and increased complexity in the prior art are also solved.

[0076] It should be understood that, although Figure 4 The steps in the flowchart of the application are displayed in sequence according to the arrows, but these steps are not necessarily executed in sequence according to the arrows. Unless otherwise specified in this document, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, Figure 4 At least part of the steps in the application can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with other steps or sub-steps or stages of other steps.
