[technical background]

Three-dimensional computer-generated image is a three dimensional representation of utilizing the geometric data of storage.Utilize these data to calculate to play up and obtain being used for the two dimensional image that shows after a while or watch in real time.These geometric datas normally are stored in a graphics data file, this three-dimensional object of expression on mathematics.Be called the processing of playing up (rendering) by one, this object is shown as a two dimensional image.

Before playing up generation, one or more objects can be placed in the virtual scene (scene).The layout of these objects and attribute definition the spatial relationship between these objects, comprise position and size.An animation can define the sequential description (temporal description) of an object, such as, how this object moves and distortion in time.Animation method commonly used comprises key frame (keyframing), inverse kinematics (inverse kinematics) and motion-captured (motion capture).Also can motion be described by physical simulation.

Based on described scene, play up real two-dimensional picture of generation or animation and be used for showing.Some different rendering intents that have their own characteristics each are available.Play up (distinctly non-realistic wireframe rendering) to playing up again to the more advanced technology of playing up from the unreality wire frame of uniqueness based on polygonal, as sweep trace play up (scanline rendering), ray tracing plays up (raytracing) or (radiosity) played up in the luminous energy transmission.Playing up one width of cloth/frame picture may need several seconds to several days, and it calculates very expensive usually.

Some technology have been developed and have been used for the effect that simulating nature takes place, such as the interaction between light and the other forms of material.The example of these technology comprises that particIe system (particle systems) (can simulate rain, cigarette or fire), volume sampling (volumetric sampling) (but simulate fog, dirt and other space atmosphere effects), caustic (caustics) (is used to simulate converging of light that irregular anaclasis surface produced, ripple such as the light that can see in the swimming pool bottom), ray tracing (producing a picture through the path of pixel in the picture plane by following the tracks of light) and Subsurface Scattering (subsurface scattering) (are used for analog optical fiber in solid object, such as people's skin, in reflection).

Non-interactive medium, such as film and video recording, animation comprise in order a plurality of frames that show.These frames are to play up acquisition with relatively slow speed and relative higher quality.Play up a frame time may from several seconds to, if the scene more complicated, several days.The frame of playing up acquisition can be stored in the storer, and can be transcribed into other media, such as cinefilm or CD.These frames are play with higher frame speed according to the order of sequence, are generally per second 24,25 or 30 frames, to obtain the vision of motion.

Existing three-dimensional visualization software adopts a kind of limited method that comprises the following step of clearly describing consuming time to revise a scene and produce a sequence accordingly.At first set up a camera position, then describe role's behavior, arrange texture again, adjust material then, light is set again.After finishing each step, in check result with before doing possible change, the user wants instruct computer to do to play up.If change, this scene also will be played up once to check again so.Add existing software and play up consuming time longlyer, this method is very loaded down with trivial details and not directly perceived, to the creativeness of encouraging the user without any benefit.

The method of existing lifting performance comprises plays up task with some, painted such as light layer and material, gives Graphics Processing Unit.Adopt the example of the software of this method that Gelato is arranged and at D S tudioMax user's Click-VR.But these softwares still require the user playing up scene with each variation in this scene of definition before checking.

Existing scheme provides a user interface that is used for receiving from the user object value (object value) of a scene.The order of playing up this scene of respective user, these values are provided for a processing unit and play up.This processing unit is carried out necessary calculating and is exported one and play up.For example, this processing unit can be a central processing unit.Unfortunately this method is more loaded down with trivial details and speed is slower, forces the user to enter a process of creating a scene repeatedly.

In addition, existing method will define the original state of each object in this scene when playing up each frame of an animation sequence, partly plays up according to former frame then and obtains each frame.This makes and shows that at random an intermediate frame (such as in the process of montage) becomes very consuming time, because must at first play up each frame before obtaining.
