Description of drawings
Fig. 1 is the process flow diagram of a specific embodiment of method of a kind of three-dimensional software control of the present invention performance.
Embodiment
Please referring to shown in Figure 1, the invention provides a kind of method of three-dimensional software control light, it may further comprise the steps.
The invention provides a kind of method of three-dimensional software control performance, it may further comprise the steps:
Step 101 is made the dummy model consistent with the stage image structure in three-dimensional software, and associated virtual model and real scene shooting model corresponding sampling points and articulation point.
In a specific embodiment, described stage image is puppet or figure for shadow-play.Described dummy model and stage image equal proportion have the articulation point of equal number, and described sampled point equal proportion distributes.
Described dummy model has identical size or equal proportion with stage image.Controlling like this can be more convenient, is unlikely to occur mistake; And the sampled point of associated virtual model and stage image can allow photometry more accurate.The intensive more relative result of sampled point is more accurate, but inevitable calculated amount can increase much the real-time variation.
And in another specific embodiment, described dummy model is a skeleton model.Because utilize three-dimensional software control physical objects to be taken not need to allow dummy model follow physical objects in full accord.The structure that only needs dummy model to have with the physical objects unanimity gets final product.Consistent structure comprises the distance between the articulation point of consistent joint position, equal proportion etc.In the process that dummy model is made, should become equal proportion with solid model as far as possible, controlling like this can be more convenient, is unlikely to occur mistake.
Step 102 according to action and movement locus and the lighting effects that stage image will be made, is made animation with dummy model in three-dimensional software.
Step 103 is play described animation, in the contrast animation in present frame and the former frame angle of articulation point change, and extract the angle of variation, the angle-data of described variation is sent to stage image, the action of synchro control stage image and movement locus.
In a specific embodiment, stage image is not that action is all arranged all the time, and all articulation points all have action to change when neither move at every turn.So those have the angle changing of the operating point of action variation just can reappear whole course of action only to need record.
In a specific embodiment, described stage image is controlled by servomotor, after described servomotor receives the angle-data of the variation that three-dimensional model sends, and the corresponding angle of articulation point rotation that control is corresponding.Described servomotor is driven by microcontroller, converts the data layout that servomotor is accepted to behind the angle-data of the variation of described microcontroller reception three-dimensional software output.
In a specific embodiment, described three-dimensional software is Maya, and it comprises the PORT COM that can Gong call.Described stage image is the machinery of servomotor control, and the turning joint point in its physical construction is corresponding with the articulation point of described dummy model.Described servomotor is subjected to micro-control unit controls, and after micro-control unit received the angle information of the variation that three-dimensional model sends, the control servomotor was to the corresponding angle of articulation point rotation of stage image correspondence.Described angle control can be controlled each joint as robot, also can utilize the control of line bar as the puppet figure for shadow-play.
Detailed process is as follows.At first open PORT COM, set up communication with maya by function C apTcpOpen (server_name).Send mel order (20ms) " getAttr objName.rx " to maya by this port at interval with certain hour then, after maya receives this order, carry out this order immediately, and by port with the form return results of character string to micro-control unit, micro-control unit writes down this result, and it is carried out corresponding data-switching and processing, obtain virtual joint angles value.At last, micro-control unit is sent to servomotor by the com port with data.
Wherein # is a start mark, and 00A is a port number, and XXX represents joint angles system,! Be end mark.
Step 104 is play described animation, and the sampled point on the dummy model is sent to the light battle array at the light intensity data of each frame, and adjusts the light of light battle array according to described light intensity data.
In a specific embodiment, described light intensity data is the rgb light strength component, and described light battle array is a light of stage, and described light battle array is controlled by control circuit, after described control circuit receives the light intensity data of three-dimensional model transmission, change the brightness and the color of light on the light battle array.
Described control circuit is driven by microcontroller, converts the data layout that control circuit is accepted to behind the light intensity data of described microcontroller reception three-dimensional software output.
Concrete steps comprise that microcontroller sends the mel order of the rgb light strength component that obtains each sampling point position by mode and the Maya communication of similar soket to Maya.When receiving after Maya calculates the rreturn value finish, microcontroller is translated into specific coding and sends on the control circuit by interface.
In a specific embodiment, brightness and color that described control circuit changes light on the light battle array adopt width modulation, by modulating pulse dutycycle control lamplight brightness.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement etc., all should be included within protection scope of the present invention.
