Description
Technical field
The present invention relates to computer multi-media system and three dimensional computer graphics animation system, particularly the music animation system of three-dimensional plant body.
Background technology
Modeling and sense of reality drafting about plant are one of focuses of graphics area research always.People have done a large amount of fruitful work, yet the research of relevant plant animation is rare, and pay close attention to the growth animation of plant more, realistic plant movement simulation is owing to have higher motion complexity and scene complexity, and description, control and the realization of this type games had bigger difficulty.And, because plant has higher freedom of motion, having brought very big difficulty to finding the solution the equation of motion, real-time animation just is difficult to realize more.Existing most of virtual Dance System adopts the visual human as its cartoon role, and great majority are utilization movement capturing technologies, catch the people's of real world action message by motion-captured device (magneto-electric or photo-electric), then by various movement synthesis methods, motion is reoriented to virtual dancing role, generates motion animation sequence true to nature.This method needs comparatively complicated and expensive motion-captured device, and need to gather a large amount of true personages' exercise data, and synthetic new motion difficulty comparatively, synthetic motion often is the simple repetition of the real motion that captured, gives the plodding sensation of people unavoidably.
Summary of the invention
The object of the present invention is to provide a kind of three-dimensional plant body music animation system.
For achieving the above object, a kind of three-dimensional plant body music animation system comprises computer unit, audio playing unit and video display unit;
Described computer unit can pass through embedded software, the music file of analyzing stored in music libraries;
Described computer unit can also pass through embedded software, calculates and the continuous animated video of automatic generation, and vision signal is outputed to video display unit;
Described audio playing unit is used for playing audio signal;
Described video display unit is used for display video data;
It is characterized in that described computer unit comprises:
3 d graphic library is used to store the model of various three-dimensional plants;
The real-time animation sequence generates and the real-time rendering module, is used for generating automatically and playing up real-time dance movement;
Dancing attitude storehouse is used to store various dancing attitudes;
Automatically the dancing rule module is used to produce the dance movement layout data;
The dance movement script module is used to store the dance movement data.
The present invention is under the situation that does not need motion-captured device, and the motion of simulating plant body realistically generates the dancing motion animation sequence of three-dimensional plant body in real time.The present invention can also allow user oneself editor dancing attitude and action, thereby can the layout generation and the dancing animation of music style harmony.For the user provides an intelligent entertainment system that integrates multinomial technology such as music, dancing, three dimensional computer graphics, 3d computer animation.The used method of the present invention is made at multimedia movie, and fields such as multimedia recreation development of games and multimedia advertising making have application prospect.
Description of drawings
Fig. 1 is a three-dimensional plant body music animation system composition frame chart of the present invention.
Embodiment
Accompanying drawing 1 is a system architecture diagram of the present invention.Total system is divided into three unit: computer unit 10, sound equipment output unit 20 and video display unit 30.Computer unit comprises a music libraries 101 of being made up of various music files, CD CD, disc etc.; Computer unit is built-in with music signal processing module 102 and is used for handling and discerning music signal, so that key elements such as the time of control dance movement, style, dynamics; Music playing module 103 is used for playing back music, gives audio playing unit 20 with audio signal output.Also be built-in with 3 d graphic library 111 in the computer unit, the model of storing various three-dimensional plants is used for the dancing animation; The real-time animation sequence generates and real-time rendering module 112, to from dancing attitude storehouse 113, extract attitude data, produce the dance movement layout data from automatic dancing rule 114 modules, or from dance movement script 115, extract the dance movement data, generate and play up real-time dancing animation automatically.Computer unit also provides three-dimensional modeling 121, dancing attitude editor 122,123 3 interfaces that exchange with the user of dance movement layout, so that system can generate plant model, dancing attitude and dance movement by user oneself definition.The melody output audio signal of computer unit and animation outputting video signal are connected respectively to audio playing unit 20 and video display unit 30, with playing back music and demonstration animation.
Embodiment
Music file is directly left in the data storage part of computer unit, as hard disk, read-only memory can be wiped reservoir, or flash memory etc., form a music libraries; Perhaps can realize the broadcast of music by CD device or outside other music player.For example, we have stored the music of tchaikovsky's " Swan Lake " as nautch.The shape library that comprises various plant three-dimensional datas in the interior foundation of native system.For example, we set up the lily model of a three-dimensional by the three-dimensional modeling module, and as the leading role of dancing animation, it is made up of a stem, four leaves and a flower being positioned at the top.These organs all can move when dancing, and anthropomorphic dummy's trunk and four limbs make various motion in different poses and with different expressions.In native system, set up and the corresponding dancing attitude of various plant models storehouse.For example, we are divided into flower, stem and six parts of four branches and leaves with the liliaceous attitude of cartoon role, each part set up respectively again some kinds of representative attitudes (such as, can have for flower part: the hanging low of flower, high, lateral deviation and reverse etc.).In native system, set up the action script file of the dance movement that comprises various plant dance movement sequences.For example, we set up the targeted attitude of each beat according to the natural beat of music, and system can be according to the transfer and the conversion that realize automatically based on the kinetic model of physics between attitude, thereby generates dance movement miscellaneous.Add the action of some control dancings of overall importance, as move, jump, rotation etc., just can form a complete dancing script file, the dancing cartoon role just can be according to the link up dancing of smoothness of the dancing script of being write.Set up the audio signal processing unit that music factor (as beat, high pitch, bass, drumbeat etc.) extracts and discerns at the embedded software of native system.For example, we can adopt the method for spectrum analysis, extract and discern the height of tone.For the situation of source of sound employing MIDI, we can set up the MIDI analytic unit, extract information such as the contained pitch of MIDI music signal kind, the duration of a sound, beat, to control the dancing of cartoon role more accurately.The software interface mode of man-machine interaction during the user shows by computer screen is selected the plant animation mode of writing music for a song, and can write music for a song manually or automatically write music for a song.For example, the mode that our selection is write music for a song manually so just also needs further to select the dancing script, and the mode that we introduce in can going on foot according to the 4th be write the dancing script and be preserved and be elected to be current dancing script.After the user clicks sign on, system will play selected melody, and generate and the corresponding dancing animation of melody simultaneously, and audio frequency and vision signal are output in audio playing unit and video display unit.Audio playing unit comprises power amplifier, loudspeaker, audio amplifier.Video display unit comprises LCD, plasma scope, rear-projection or pre-projecting type display.Display can show or multimachine combination demonstration by unit.
