Embodiment
Described three-dimensional animation, the animation that is based on a kind of three-dimensional stereograph technology and produces, this three-dimensional stereograph is made up of along compact side by side the arranging of imaging surface vision horizontal direction a succession of similar monomer image, and these similar monomer image numbers are more than or equal to 2.The two-layer information of the distinguished portability of described three-dimensional stereograph, ground floor surface picture information view sees that method and normal image do not have too big difference, and eyes are focused on picture the place ahead to second layer information need observer or the stereo-picture that has concave-convex sense just can be found out in the rear.Two-layer information can performing content do not had contiguity, can not having on the content of performance of ground floor information and second layer information got in touch, for example the ground floor performance is the woods, and second layer performance is the implicity of a bird (also can be related or relevant) second layer information, second layer information not easily the observed person find out, need the observer to face image and just can find out the place ahead or rear that eyes focus on image; Can't skillfully watch out three-dimensional stereograph to get the beholder, need just can find out after the repeatedly also patient training, so the implicit content of the second layer tantalizes for those out of patience beholders very much.Need not by any utility appliance, be different from other 3-D cartoons in the past, not need by what special glasses or watch equipment to utilize eyes just can find out the stereoeffect that has concave-convex sense.For the dependence of computing machine, make the superior three-dimensional stereograph of a width of cloth effect, need depend on the comparatively complicated calculating of a large amount of computing machines can solve, and is difficult to depend on simple craft and draws.
The specific implementation method of three-dimensional animation, elder generation comes out with the three-dimensional stereograph that the software development of making three-dimensional stereograph goes out a series of single width, and then utilize the instrument of cartoon making or film making that the picture of these these single width is combined according to order, make each frame of animation all be placed with a width of cloth three-dimensional stereograph, and adjust the image size and the position of the three-dimensional stereograph in each frame, can mix sound as required, these pictures are sequenced when playing animation shows on screen, reaches animation effect.
The three-dimensional stereograph that making can far be seen, this three-dimensional stereograph of can far seeing is made up of two or more similar arranging along imaging surface vision horizontal direction of monomer image, and the width of monomer whose image can be greater than the eyes eye-distance; The breadth of this three volume images can far seeing can be done very greatly, and is fit to be placed on and watches at a distance, can produce fine and smooth more concave-convex sense image effect; The beholder focuses on zone, picture the place ahead to the eyes sight line when watching the Ke Yuanguan three-dimensional stereograph, just can find out the optimum efficiency that has stereo concave-convex sense image.
Common three-dimensional stereograph generally can only be placed on nearby and watch now, if be placed on the words that the distant place is watched by simple amplification, the concave-convex effect variation or the distortion of image, this all is based on accompanying drawing 3 principles owing to most of three-dimensional stereograph or its shortcut calculation is made.The 3 D stereo that goes out with reference to the modelling of accompanying drawing 3 is decorated with two characteristics makes the three-dimensional stereograph under this principle can't be fit to sight far away: 1) two sight line intersection points are at the screen rear, distance between corresponding 2 is less than eye-distance (AB＜ED), because screen is placed at a distance, corresponding 2 distance can not surpass eye-distance all the time, causes the resolution decline of the image on the screen that naked eyes see; 2) two sight line intersection points are at the screen rear, eyes will be greater than the distance of eyes to screen to the distance of three-dimensional thing, because eyes sight line judging distance relies on two angle of sight JXl and JXr to judge, when screen is placed from the binocular distance far away more, three-dimensional thing is also just far away more from the binocular distance, the variable quantity that JXl and JXr produce when binocular is watched three-dimensional thing also will be few more, and the sensitivity of eyes judgment object distance also just descends thereupon, and cause the decline of concave-convex sense.The simple three-dimensional stereograph of making based on accompanying drawing 3 principles of saying, far away more from the eyes distance, the concave-convex sense that picture produced is just bad more, so and be not suitable for watching at a distance.
The three-dimensional stereograph that can far see is based on the three-dimensional stereograph that the principle of Fig. 1 is made, be different with the principle model of Fig. 3, and the three-dimensional thing of Fig. 1 is at screen and between two.1) two sight line intersection points are in the place ahead of screen, and the distance between corresponding 2 can not be limited greater than eye-distance, because the distance of two corresponding point can be greater than eye-distance, then the stereoscopic sensation that stereogram showed can be more clear, and stereovision is fine and smooth more; 2) intersection of two sight lines can not shielded and be placed far and near influence in the place ahead of screen, no matter how far screen is placed, as long as the position of fixing three-dimensional thing is for nearby, the size of corresponding change screen, the three-dimensional stereograph of producing can reach good concave-convex sense effect, and is not shielded the influence of placing at a distance.
The three-dimensional stereograph that making can far be seen, at first, according to shown in Figure 1, find earlier screen go up a some A (Ax, Ay, Az) with B (Bx, By, Bz) corresponding 2 funtcional relationship F, F satisfies A=F (B), B=F
-1(A), that is to say from the coordinate of ordering and obtain the coordinate that B is ordered, obtain the A point coordinate by the B point coordinate by A.The concrete grammar of F is as follows, according to screen point B and right eye coordinate, obtains the focus W of right eye sight line and three-dimensional thing, computer implemented method (computing method are not unique, and the method can be for referencial use)
