Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
As shown in Figure 1, the invention provides a kind of method mobile terminal being applied reverse dynamics simulation true man action, comprise the following steps:
S1, is split as multiple independently key position by object;
In the present invention, key position comprises one or more in the head position of object, body part, arm position, hand position, leg position and foot position.Certainly, also according to the simulation precision of simulates real human action, object can be split further.Basic disassembly principle is: be split benchmark with joint, and every part that there is joint association, all can split based on joint, such as: there is joint between arm position and hand position, then can split out arm position and hand position.As shown in Figure 2, for splitting 13 key positions obtained, be respectively: head position, body part, left leg position, right leg position, left thigh position, right thigh position, left arm position, right arm position, left hand position, right hand position, left foot position, right crus of diaphragm position and sword position.
S2, for each described key position generates key position picture; And, the hierarchical relationship of key position described in each is set; And, the joint data between every two key positions be associated are set;
In this step, hierarchical relationship can be father and son's hierarchical relationship, and such as, can be axle center with health, body part is set to root node, and left arm be the child node of body part, and left hand is next level of child nodes of left arm.The key position be associated is called father's key position and sub-key position; Joint data comprise: angle information, the node location information of father's key position and the node location information of sub-key position that the length information of father's key position, the length information of sub-key position, father's key position allow described sub-key position to rotate.Such as: take arm as child node, health is father node, then the data that joint data record arm is relevant with the joint point that health intersects.By joint data, when can judge that child node is moved, father node can be driven to move further.
S3, based on described key position picture and described hierarchical relationship, splicing generates the stationary objects thing on mobile terminal;
As Fig. 3 for shown in, splice by Fig. 2 the stationary objects thing obtained.
S4, if the 1st key position, the 2nd key position ... n-th key position is the key position be associated in turn; It is integer that n is more than or equal to 1, n;
When the described 1st key position action of described stationary objects thing, if movement range meets the joint data between described 1st key position and described 2nd key position, then drive described 2nd key position action; If movement range does not meet, then stop;
If the movement range of described 2nd key position meets the joint data between described 2nd key position and the 3rd key position, then drive described 3rd key position action, the rest may be inferred, forms the animation of simulates real human action.
Such as, carry out attack to simulate personage, when sword travels forward, the upper level position due to sword is arm, therefore, drives arm to advance; Upper level position due to arm is health, when arm motion reaches required amplitude, drives forward lean, successively drives whole body, complete attack.
As shown in Figure 4, the present invention also provides the device a kind of mobile terminal being applied reverse dynamics simulation true man action, comprising:
Split module, for the action situation according to object, object is split as multiple independently key position;
Generation module, generates key position picture for splitting each described key position obtained for described fractionation module;
Module is set, for arrange described fractionation module split obtain each described in the hierarchical relationship of key position; And, described fractionation module is set and splits joint data between every two key positions be associated of obtaining;
Concatenation module, for the described key position picture that generates based on described generation module and the described described hierarchical relationship arranging module installation and obtain, splicing generates the stationary objects thing on mobile terminal;
Animation producing module, for: establish the 1st key position, the 2nd key position ... n-th key position is the key position be associated in turn; It is integer that n is more than or equal to 1, n;
When the described 1st key position action of described stationary objects thing, if movement range meets the joint data between described 1st key position and described 2nd key position, then drive described 2nd key position action; If movement range does not meet, then stop;
If the movement range of described 2nd key position meets the joint data between described 2nd key position and the 3rd key position, then drive described 3rd key position action, the rest may be inferred, forms the animation of simulates real human action.
Mobile terminal provided by the invention is applied the method for reverse dynamics simulation true man action, do not need to store multiple frame animation pictures, can animation be generated by computing, thus the storage space taken when effectively reducing animation producing and running memory; In addition, by this kind of method, effectively can avoid the problem of motion picture distortion, improve animation simulation degree.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should look protection scope of the present invention.
