A is please referred to Fig.2, it illustrates the flow charts of virtual objects presentation method provided by one embodiment of the present invention, originally
Embodiment with the virtual objects presentation method applied to come in terminal for example, in the terminal operation have video living transmission system
Client, the client be application client or webpage client, the present presentation method can include but is not limited to
Lower step：
In step 201, during net cast, the slip gesture on net cast picture is received.
Video living transmission system includes：Server and client side.Client includes：Main broadcaster client used by a user is broadcast live
End, and, spectators' spectator client used by a user.
In the same net cast room, spectators user can watch the live video of live streaming user.That is, live streaming is used
Family uploads live video stream by main broadcaster's user end to server, and server is by live video stream multicast or is broadcast to same video
Multiple spectator clients in room are broadcast live, are checked for spectator client." net cast room " is in different video living transmission systems
In, " channel ", " studio " etc. can also be known as.
During spectators user uses spectator client watching video live broadcast picture, if terminal has detected touch screen
The action of curtain judges whether the touch action is slip gesture, or, judging the touch operation when occurring on net cast picture
Whether it is scheduled slip gesture.
Optionally, when the IOS operating system provided using American apple company in terminal, a kind of judgment method is：Root
Judge whether touch action is slip gesture according to the detection program of common slip gesture Pan in IOS systems (towing gesture).It can
Choosing, terminal identifies that this is touched according to the detection program of UISwipeGestureRecognizer (gently sweeping gesture) in IOS systems
Touch whether action is slip gesture, but the present embodiment is not specifically limited the judgment method of slip gesture.
During net cast, if terminal judges that the touch action on net cast picture is slip gesture, eventually
End receives the slip gesture.Optionally, terminal detects whether the slip gesture is scheduled slip gesture, scheduled slip gesture
It is for triggering the slip gesture for giving virtual present, for example, the gesture slided from the bottom of net cast picture to top.Only
When slip gesture is scheduled slip gesture, step 202 is executed.
In step 202, detection active user's account number whether there is in the virtual present that can give state.
In one possible implementation, the user account number of spectators user possesses unlimited use condition and/or uses number
The virtual present of amount；In alternatively possible realization method, just possess when the user account number of spectators user conforms to a predetermined condition
In the virtual present that can give state, for example, the user account number of spectators user is paid for user or VIP user；At another
In possible realization method, the user account number of spectators user be only capable of possessing within each period limited quantity in can give
The virtual present of state possesses 5 in the virtual present that can give state for example, per an online hour.
In a possible embodiment, it in net cast room, after virtual present is sent once, needs in identical live streaming
Viewed status is maintained in room for a period of time, and client can be just obtained again in the virtual present that can give state.Therefore, exist
When receiving slip gesture or scheduled slip gesture, the client that is run in terminal whether there is in can active user's account number
The virtual present for giving state is detected.
Such as：When a certain user to live streaming user gave virtual present after, this live streaming room in watch 600s
Just there can be virtual present to give qualification again afterwards.
Optionally, the qualification for giving virtual present can not also be limited, that is, during net cast, user
After giving a virtual present to live streaming user, virtual present can be given again at any time, it is not necessary in identical live streaming room
Between middle waiting.
If it is detected that active user's account number exists in the virtual present that can give state, 203 are thened follow the steps；Otherwise,
Then execute 212.
In step 203, the sliding trace parameter of slip gesture is recorded；The sliding trace parameter includes：The sliding trace
Starting point coordinate, and, the coordinate of other sampled points in the sliding trace in addition to starting point；The sliding trace parameter further includes：
The glide direction and sliding speed of other sampled points.
Terminal can sample the slip gesture received, and record the sliding trace parameter of slip gesture.Slide rail
Mark parameter includes：The starting point coordinate of sliding trace, and the coordinate of other sampled points in addition to starting point, glide direction and sliding speed
Degree.
Optionally, other sampled points are terminals every pre- fixed sample interval point collected to sliding trace.
Optionally, other sampled points are the inflection point that is identified in sliding trace of terminal, and the recognition methods of the inflection point can be with
For：When terminal detects that coordinate of certain point on sliding trace makes the second dervative of sliding trace be zero, and three order derivatives are not
When zero, judge the point for the inflection point of sliding trace.The present embodiment is not defined the judgment method of inflection point in sliding trace.
In conjunction with examining Fig. 2 B, on net cast picture 1, terminal receives sliding trace 20, and to the sliding trace 20 into
Row sampling, midpoint 21 are starting point, and point 22 is other sampled points.
In step 204, whether the number for detecting other sampled points reaches predetermined number.
After terminal-pair slip gesture is sampled, the other sampled points obtained will at least reach predetermined number, this default
Number is set by developer, and numerical value can be 4,5,6,7 etc., and the present embodiment does not limit.
After terminal collects other sampled points, need whether the number for detecting other sampled points reaches predetermined number.If reaching
To predetermined number, 205 are thened follow the steps；If not up to predetermined number thens follow the steps 210.
In step 205, starting point coordinate, the coordinate of other sampled points and scheduled terminal point coordinate are inputted into Bezier
In generating algorithm, target Bezier is obtained；
When other sampled point numbers are more than or equal to predetermined number, then terminal can be other by the starting point coordinate of record
The coordinate of sampled point and scheduled terminal point coordinate are input in Bezier generating algorithm.The scheduled terminal point coordinate can be
Coordinate positioned at a corner of net cast picture, for example, upper left corner or bottom right corner.
Optionally, terminal is according to Bezier formula：
Set point P0, P1, P2 ... Pn, Bezier are：
Wherein, time/time for consume from animation starting point to scheduled terminal of t=current sampling points consumption, current wiping
The time of itchy points consumption is time for being consumed to current sampling point since animation；Pn is the coordinate of n-th of point point, and n is big
In the positive integer equal to 0.
Target Bezier is obtained by above-mentioned algorithm.
In step 206, according to target bezier curve, at least one crucial frame coordinate of virtual present is determined.
Terminal determines at least one crucial frame coordinate according to obtained target Bezier.Crucial frame coordinate is virtual
Coordinate of the present on the animation key frame when sliding display on net cast picture.
Specifically, the method linearly filled up may be used in terminal or the method for IOS system curve animations sits key frame
Mark is determined.The present embodiment does not limit the determination method of crucial frame coordinate.
In step 207, present is obtained according at least one crucial frame coordinate and shows track.
Terminal obtains display rail of the virtual present in live video picture according to determining at least one crucial frame coordinate
Mark.
In a step 208, virtual present is shown that track carries out animation and shows along present.
In conjunction with reference to figure 2C, on net cast picture 1, virtual present " star " 5 shows track 23 into action along present
Draw display.That is, virtual present " star " 5 shows that the starting point of track 23 occurs from present, sliding display to scheduled terminal 4
It disappears.The present shows that the starting point of track 23 is also the starting point of slip gesture.
In step 209, present is sent to server according to slip gesture and gives instruction, which gives instruction for referring to
Show that request server gives virtual present to the live streaming user of net cast.
After slip gesture or scheduled slip gesture that terminal receives, while showing virtual present, terminal can also
It generates and gives instruction for giving the present of virtual present to live streaming user.At this moment, terminal can send present to server and give
Instruction and the user account number logged in the terminal, the present give instruction and are used to indicate live streaming of the request server to net cast
User gives virtual present.
Live streaming user is the supplier in net cast room.
As the alternatively possible branch of step 204, if the number for other sampled points that terminal is got is not up to pre-
If number thens follow the steps 210.
In step 210, at least one prediction samples are predicted according to the glide direction of other sampled points and sliding speed
Point.
When inflection point is less in the sliding trace that terminal receives, alternatively, the sliding trace received is shorter, alternatively, sliding rail
Mark has one section when marking except net cast picture, the case where causing the number of other sampled points that predetermined number is not achieved.
When getting the number of other sampled points and other sampled points in terminal and being not up to predetermined number, terminal is according to acquisition
Glide direction, sliding speed and the coordinate of the last one the other sampled point arrived predict the coordinate of first prediction samples point.
If the number summation of other sampled points and first prediction samples point does not reach predetermined number also, terminal is adopted according to the first prediction
The coordinate of sampling point and the glide direction of the last one other sampled point and sliding speed continue to predict second prediction samples point,
Until reaching predetermined number.Optionally, following algorithm can be used in prediction technique：
The coordinate of the coordinate of first prediction samples point=the last one other sampled point+the last one other sampled point
Direction vector × preset time of speed × the last one other sampled point.
The speed of coordinate+the last one other sampled point of the coordinate=the (n-1)th prediction samples point of n-th of prediction samples point
Direction vector × predetermined time of degree × the last one other sampled point.
Preset time in above-mentioned algorithm can be by Developmental Engineer's sets itself, such as：0.1s, 0.2s, 0.3s etc., this implementation
Example does not limit.
In step 211, by starting point coordinate, the coordinate of other sampled points, the coordinate of prediction samples point and scheduled terminal
Coordinate inputs in Bezier generating algorithm, obtains target Bezier.
The coordinate of starting point coordinate, scheduled terminal point coordinate, the coordinate of other sampled points and prediction samples point is input to shellfish
In Sai Er Curve derivative algorithms.
Optionally, according to Bezier formula：
Set point P0, P1, P2 ... Pn, Bezier are：
Wherein, it time/time for being consumed from animation starting point to scheduled terminal of t=current sampling points consumption, currently adopts
The time of sampling point consumption is time for being consumed to current sampling point since animation；Pn is the coordinate of n-th of point point, and n is big
In the positive integer equal to 0.
Target Bezier is obtained by above-mentioned algorithm, executes step 206.
As a possible branch of step 202, if active user's account number, which is not present to be in, can give the virtual of state
Present thens follow the steps 212.
In the step 212, it if it is detected that active user's account number is not present in the virtual present that can give state, reminds
There is no in the virtual present that can give state.
For example, will appear the printed words of " present that can be given is not present in you " on the display interface of terminal.
In conclusion virtual objects presentation method provided in an embodiment of the present invention, by according to slip gesture to server
It sends present and gives instruction；It is sampled according to slip gesture, shellfish plug is generated according to sampled point and track starting point and default terminal
That curve；According to target bezier curve, at least one crucial frame coordinate of virtual present is determined；According at least one key frame
Coordinate obtains present and shows track；The virtual present is shown that track carries out animation and shows along the present.So that user can
By that live streaming user can be given to give virtual present in net cast region slip gesture, it is not necessary to select gift from present inventory
Object is sent, and is blocked live streaming picture when solving selection present inventory, is given virtual present problem complicated for operation, reach
Net cast picture need not be blocked in the process by giving virtual present, simplify the step of giving virtual present, save the operating time
Effect.
In addition, by generating target Bezier according to the slip gesture of user, determined according to target Bezier
Crucial frame coordinate, the method for finally showing track according to key frame Coordinate generation present solve aobvious according to user's sliding trace
The undesirable problem of the animation curve that shows has reached the present shown in video area more coherent, essence of giving curve of sliding
Accurate effect.
It should be added that in this step 210, when being sampled to sliding trace, there may be two kinds of special feelings
Condition, optionally, terminal-pair should make following processing：
1) when the slip gesture received is straight line, inflection point, other sampled points that terminal obtains are not present at this time
Number is zero, and at this moment, the predetermined animation that terminal can use developer to set in advance shows track giving virtual present
Journey is shown in net cast picture.
D is please referred to Fig.2, Fig. 2 D are slip gesture design sketch that virtual objects when being straight line give, user is straight in video
The gesture 30 that a upward sliding is made in picture 1 is broadcast, the gesture of the upward sliding is straight line.At this point, virtual present 5 is pressed
Show that track 24 reaches scheduled terminal 4 according to predetermined animation.That is, virtual present 5 can be a star present, the virtual gift
Object 5 shows that the starting point of track 24 occurs from predetermined animation, then shows that track 24 is moved along predetermined animation, and predetermined being moved to
Terminal 4 when disappear.
If 2) sat according to the prediction samples point that the last one other sample point coordinate predicts according to the method in this step
It is marked on the outside of net cast picture, then uses following algorithm：
The speed of first prediction samples point coordinates=the last one sample point coordinate+the last one other sampled point × pre-
Direction vector × time of fixed terminal, alternatively,
The speed of coordinate+the last one other sampled point of the coordinate=the (n-1)th prediction samples point of n-th of prediction samples point
Direction vector × time of degree × scheduled terminal.
The direction vector of the scheduled terminal is the vector that scheduled terminal is directed toward from the last one other sampled point.
Scheduled terminal in above-mentioned algorithm is the terminal that virtual present shows arrival in net cast picture, it is one
A fixed position, is set by developer.Such as：In the upper left corner of net cast picture, the upper right corner, the lower left corner, lower right corner etc..
Please refer to Fig.2 E be prediction samples point coordinates on the outside of net cast picture when the design sketch given of virtual objects.
