The camera shake simulation method, device and storage medium in the game provided by the embodiments of the present invention are described below with reference to a plurality of examples.
Fig. 1 is a flowchart of a method for simulating camera shake in a game according to an embodiment of the present invention. The camera shake simulation method in the game can be realized by executing corresponding software codes by a processing device, such as a processor, of the terminal installed by the game software/client, or by executing corresponding software codes by the processing device of the terminal and combining other hardware entities. Examples of the terminal include a desktop computer, a notebook, a Personal Digital Assistant (PDA), a smart phone, a tablet computer, and a game machine. The embodiment is described with a terminal as an execution subject.
The processor of the terminal can generate a game interactive interface by executing the software application and rendering on the display equipment of the terminal, and during the process of generating the game interactive interface, a virtual object corresponding to a game can be generated by rendering on the game interactive interface. The virtual object may be referred to as a game object, or, an object. Specifically, the player may download a game-like application program or a web page program of a browser and install the game-like application program or the web page program on the terminal, and if the game application runs on the terminal, the game interaction interface may be rendered and generated on a display device of the terminal. The player can operate through the game interaction interface of the display device of the terminal to realize the control of the virtual object, so as to play the game.
During the game, the camera is often required to be shaken to simulate the reality of the picture so as to enhance the experience of the game that the player is personally on the scene.
As shown in fig. 1, the method for simulating camera shake in a game according to the present embodiment includes the following steps:
s101, determining the focal position of the camera, and focusing the object on the focal position.
The focus object as referred to herein means an object desired to be focused.
And S102, determining the shaking amplitude of the camera according to the focus position.
The jitter amplitude may be a position offset or an angle offset within a preset range.
That is, the camera may also have a shake magnitude after focusing on the focal position.
Compared with the scheme that camera shake is simulated by randomly adjusting the position of a camera within a range in the related art, the embodiment of the invention firstly determines the focal position of the camera to enable a focused object to be in the focal position, and then determines the shake amplitude of the camera according to the focal position, so that the focused object is ensured to be always present in the screen of the camera, and the game experience of players is improved.
On the basis of the above-described embodiment, in the following embodiment, the shake amplitude is an angular deviation, considering that when the position of the shake amplitude within the preset range is changed, the shake of the picture is caused, and the player is likely to be uncomfortable. Various forms of camera shake are simulated by changing the rotation angle of the camera in different frame pictures. Wherein the various forms include different amplitudes, different frequencies.
In one implementation, the determining, according to the focal point position, a shake amplitude of the camera S102 may include: and determining the shaking amplitude of the camera by taking the focus position as a reference according to the shaking starting time of the camera, the preset shaking frequency and the shaking duration. The preset jitter frequency is used for representing the size of a time scaling factor, namely the speed of the change of the camera angle along with the time; the shake duration is used to indicate the duration of shake, i.e., the time elapsed from the start of camera shake to the present time.
The preset jitter frequency is related to an application scene, and different values can be set under different situations. For example, when the preset jitter frequency is low, the ground jitter and the cloud camera jitter can be simulated; the dither frequency may be generated when the predetermined dither frequency is high.
Further, determining a shake amplitude of the camera according to the moment when the camera starts shaking, a preset shake frequency and a shake duration may include: determining the shake amplitude of the camera according to the following formula:
angle＝Func(t+D*F)
the Func () function is a function with a period of T and an amplitude of [ -a, a ], the jitter duration is represented as D, the preset jitter frequency is represented as F, and the time when the camera starts to jitter is T. It can be understood that the range of variation of the shake amplitude of the camera is an angular offset of [ -a, a ], that is, the maximum shake amplitude is a, the minimum shake amplitude is 0, and the period T is a period, and the shake amplitude varies periodically, where the symbol "-" represents the opposite direction of the current preset direction.
In the camera shake simulation process, the preset shake frequency and shake duration may be preset, so that after the time when the camera starts shaking is determined, the shake amplitude of the camera may be determined according to the above formula.
Optionally, the dither amplitude may include at least one of:
jitter amplitude in pitch direction;
the amplitude of the shake in the yaw direction;
jitter amplitude in roll direction.
Wherein:
the jitter amplitude in pitch direction is the rotation around the X axis, also called pitch angle;
the dither amplitude in the yaw direction, which is a rotation around the Y-axis, is also called the yaw angle;
the roll direction jitter amplitude is the rotation around the Z axis, also called roll angle.
Since the roll-direction jitter amplitude is liable to cause vertigo, the jitter amplitude of the embodiment of the present invention is described by taking the example including the jitter amplitude in the pitch direction and/or the jitter amplitude in the yaw direction.
As an example, let tP be the time point when the camera starts to shake in the pitch direction, and now calculate the shake amplitude DP of the camera in the pitch direction, then:
DP＝Func(tP+D*F)
example two, setting tY to be the moment when the camera starts shaking in the yaw direction, and now calculating the shake magnitude DY of the camera in the yaw direction, there are:
DY＝Func(tY+D*F)
to make DY and DP different, tP and tY may be set to be random and different. I.e. in different directions, the moment at which the corresponding camera starts shaking may be the same or different. Similarly, the corresponding preset dithering frequencies may be the same or different in different directions, and/or the corresponding dithering durations may be the same or different in different directions, which is specifically set according to actual requirements, and the embodiment of the present invention is not limited thereto.
When the shake amplitude includes a shake amplitude in the pitch direction and a shake amplitude in the yaw direction, the shake amplitude in the pitch direction and the shake amplitude in the yaw direction are calculated, and then the angular offset in the corresponding direction is applied to the camera.
In some embodiments, to reduce the real-time computation amount, a continuous noise simulation Func () function corresponding track can be used in advance to generate a continuous two-dimensional curve with a period of T in advance, and the range of the vertical axis of the curve is [ -a, a ]. As illustrated in fig. 2, the horizontal axis of this two-dimensional curve represents time and the vertical axis represents offset magnitude. The two-dimensional curve is generated in many ways, and continuous noise (such as Berlin noise) is used to simulate the two-dimensional curve.
Optionally, the track corresponding to the Func () function includes a limited value, and after the jitter amplitude is obtained according to the above formula, a value closest to the jitter amplitude in the track corresponding to the Func () function is taken as the final jitter amplitude of the camera.
If the finite value of the trace corresponding to the Func function is calculated in advance and the periodic result is stored, the final real-time calculation amount is small, which is equivalent to one sampling.
The following are embodiments of the apparatus of the present invention that can be used to implement the above-described embodiments of the method of the present invention, and the implementation principles and technical effects are similar.
Fig. 3 is a schematic structural diagram of a camera shake simulation apparatus in a game according to an embodiment of the present invention. The camera shake simulation device in the game obtains a game interaction interface by executing a software application on a processor of the terminal and rendering the software application on a display device of the terminal.

a first determining module 31 for determining a focus position of the camera, wherein the focused object is at the focus position.
And a second determining module 32, configured to determine a shake amplitude of the camera according to the focal point position.
The dither amplitude may be a position offset or an angle offset within a preset range.
The camera shake simulation apparatus in a game of the present embodiment first determines the focus position of the camera on which the object of focus is located, and then determines the shake amplitude of the camera from the focus position. Because the focusing object is at the focal position of the camera, the embodiment of the invention can ensure that the object which the camera wants to focus appears in the camera screen, thereby improving the game experience of players.
On the basis of the above-described embodiment, it is considered that when the position of the shake amplitude within the preset range is changed, the shake of the picture is caused, and the player is likely to be uncomfortable, and therefore, in the following embodiment, the shake amplitude is an angular deviation. Various forms of camera shake are simulated by changing the rotation angle of the camera in different frame pictures. Wherein the various forms include different amplitudes, different frequencies.
Optionally, the second determining module 32 may be specifically configured to: and determining the shaking amplitude of the camera according to a preset shaking frequency and a preset shaking duration by taking the focus position as a reference. The preset jitter frequency is used for representing the size of a time scaling factor, and the jitter duration is used for representing the duration of jitter.
The preset jitter frequency is related to an application scene, and different values can be set under different situations. For example, when the preset jitter frequency is low, the ground jitter and the cloud camera jitter can be simulated; the dither frequency may be generated when the predetermined dither frequency is high.
Further, a second determining module 32 is configured to determine a shake amplitude of the camera according to the following formula:
angle＝Func(t+D*F)
the Func () function is a function with a period of T and an amplitude of [ -a, a ], a shaking time duration is represented as D, a preset shaking frequency is represented as F, and a time when the camera starts shaking is T. It can be understood that the range of variation of the shake amplitude of the camera is an angular offset of [ -a, a ], that is, the maximum shake amplitude is a, the minimum shake amplitude is 0, and the period T is a period, and the shake amplitude varies periodically, where the symbol "-" represents the opposite direction of the current preset direction.
In the camera shake simulation process, the preset shake frequency and shake duration may be preset, so that after the moment when the camera starts shaking is determined, the shake amplitude of the camera may be determined according to the above formula.
Optionally, the trajectory corresponding to the Func () function is simulated using continuous noise, which includes berlin noise.
Furthermore, the track corresponding to the Func () function includes a finite value, and after the jitter amplitude is obtained according to the formula, a value closest to the jitter amplitude in the track corresponding to the Func () function is taken as the final jitter amplitude of the camera.
In the above embodiment, the dither amplitude includes at least one of:
jitter amplitude in pitch direction;
the amplitude of the shake in the yaw direction;
jitter amplitude in roll direction.
Wherein:
the jitter amplitude in the pitch direction is the rotation around the X axis, which is also called the pitch angle;
the dither amplitude in the yaw direction, which is a rotation around the Y-axis, is also called the yaw angle;
the roll direction jitter amplitude is the rotation around the Z axis, also called roll angle.
Since the roll-direction jitter amplitude is liable to cause vertigo, the jitter amplitude of the embodiment of the present invention is described by taking the example including the jitter amplitude in the pitch direction and/or the jitter amplitude in the yaw direction.
As an example, let tP be the time point when the camera starts to shake in the pitch direction, and now calculate the shake amplitude DP of the camera in the pitch direction, then:
DP＝Func(tP+D*F)
example two, setting tY to be the moment when the camera starts to shake in the yaw direction, and now calculating the shake magnitude DY of the camera in the yaw direction, there are:
DY＝Func(tY+D*F)
to make DY and DP different, tP and tY may be set to be random and different. I.e. in different directions, the moment at which the corresponding camera starts shaking may be the same or different. Similarly, the corresponding preset dithering frequencies may be the same or different in different directions, and/or the corresponding dithering durations may be the same or different in different directions, which is specifically set according to actual requirements, and the embodiment of the present invention is not limited thereto.
When the shake amplitude includes a shake amplitude in the pitch direction and a shake amplitude in the yaw direction, the shake amplitude in the pitch direction and the shake amplitude in the yaw direction are calculated, and then the angular offset in the corresponding direction is applied to the camera.

The game interaction interface is obtained by executing a software application on the processor 42 and rendering on the display device 43. The player can play the game by performing operations on the game interaction interface of the display device 43 of the terminal to control the virtual object. The game interaction interface can also display scenes, prompt messages and the like in running games.
A memory 41 for storing program instructions.
The program instructions stored by the memory 41, when executed by the processor 42, cause the terminal 40 to perform the steps of:
determining a focal position of the camera on which the object is focused;
and determining the shaking amplitude of the camera according to the focus position.
The jitter amplitude may be a position offset or an angle offset within a preset range.
On the basis of the above-described embodiment, in the following embodiment, the shake amplitude is an angular deviation, considering that when the position of the shake amplitude within the preset range is changed, the shake of the picture is caused, and the player is likely to be uncomfortable. Various forms of camera shake are simulated by changing the rotation angle of the camera in different frame pictures. Wherein the various forms include different amplitudes, different frequencies.
In one implementation, determining a shake amplitude of the camera according to the focal point position may include: and determining the shaking amplitude of the camera by taking the focus position as a reference according to the shaking starting time of the camera, the preset shaking frequency and the shaking duration. The preset jitter frequency is used for representing the size of a time scaling factor, namely the speed of the change of the camera angle along with the time; the shake duration is used to indicate the duration of shake, i.e., the time elapsed from the start of camera shake to the present time.
Further, determining a shake amplitude of the camera according to the moment when the camera starts shaking, a preset shake frequency and a shake duration may include: determining a shake magnitude of the camera according to the following formula:
angle＝Func(t+D*F)
the Func () function is a function with a period of T and an amplitude of [ -a, a ], the jitter duration is represented as D, the preset jitter frequency is represented as F, and the time when the camera starts to jitter is T. It can be understood that the range of variation of the shake amplitude of the camera is an angular offset of [ -a, a ], i.e. the maximum shake amplitude is a, the minimum shake amplitude is 0, and the period T is a periodic variation, where the symbol "-" represents the opposite direction of the current preset direction.
Optionally, the dither amplitude may include at least one of:
jitter amplitude in pitch direction;
the amplitude of the shake in the yaw direction;
roll direction jitter amplitude.
Since the roll-direction jitter amplitude is prone to vertigo, the jitter amplitude of the embodiment of the present invention may include a pitch-direction jitter amplitude and/or a yaw-direction jitter amplitude. When the shake width includes a shake width in the pitch direction and a shake width in the yaw direction, the shake width in the pitch direction and the shake width in the yaw direction are calculated, and then the angular offset in the corresponding direction is applied to the camera.
In some embodiments, to reduce the real-time computation amount, a continuous noise simulation Func () function corresponding track can be used in advance to generate a continuous two-dimensional curve with a period of T in advance, and the range of the vertical axis of the curve is [ -a, a ]. There are many ways to generate this two-dimensional curve, where continuous noise (e.g., berlin noise) is used to model the two-dimensional curve.
Optionally, the track corresponding to the Func () function includes a limited value, and after the jitter amplitude is obtained according to the above formula, a value closest to the jitter amplitude in the track corresponding to the Func () function is taken as the final jitter amplitude of the camera.
If the finite value of the trace corresponding to the Func function is calculated in advance and the periodic result is stored, the final real-time calculation amount is small, which is equivalent to one sampling.
