Description

Apparatus and method for displaying three-dimensional animation}

The present invention relates to an animation display apparatus and method, and more particularly, to a three-dimensional animation display apparatus and method for repeatedly presenting a short time three-dimensional animation.

In 1834, before the film was invented, British mathematician William Horner was able to attach a continuous plane of still images to the interior of the cylinder and rotate it to view a dynamic animation through vertical grooves in the cylinder. Zoetrope). Zeptrop was one of the most widely loved optical toys until the early 20th century. Joydrop is still produced and sold as a toy or a parish, and media artists such as Gregory Barsamian [1997] and Stewart Dickson [2003] have used this principle to create interesting installations that show three-dimensional animation. In addition, Ovid Pope of the United States rotates a two-dimensional or three-dimensional animation object in U.S. Patent No. 5,970,170, and the flashing of the strobe lamp, rather than the vertical groove of the traditional Zeplop, allows you to enjoy the animation more clearly and clearly. Proposed apparatus and method.

Meanwhile, at the Ghibli museum in Japan, Bouncing Totoro is producing a three-dimensional joydrop that shows three-dimensional animation using animation characters from the studio. Similarly, Pixar, USA, has created a three-dimensional joydrop called Toy Story to provide visitors with three-dimensional animation. Museums and theme parks install three-dimensional joydrops and show them to visitors because they present lively images that are different from two-dimensional animation.

In general, three-dimensional joydrops are composed of hundreds of three-dimensional animation objects. In order to create an animation, each object must be placed in a specific position using a support. Therefore, most three-dimensional joydrops have to take complicated and huge structures, are not easy to manufacture, and require considerable cost and effort. For this reason, it was mainly produced and installed as an artistic work in a large-scale theme park or a museum, and for the sake of safety, the viewers had to feel at least a certain distance from the huge installation.

Therefore, the problem to be solved by the present invention is to provide a three-dimensional animation display device and method that can be easily miniaturized to implement three-dimensional animation and embedded in everyday objects, so that viewers can easily interact with the animation. will be.

 According to an aspect of the present invention, there is provided a three-dimensional animation display device comprising: a transparent disk including a plurality of three-dimensional animation objects formed while maintaining a constant angular distance; An illuminant array located annularly around the transparent disk and blinking toward an animation object in the transparent disk; Rotating means for supporting the transparent disk and rotating it at a constant speed; And a controller module for controlling the rotational speed of the rotation means and the flashing frequency and the flashing time of the light emitting array.

Here, a transparent cover is coated with a film surrounding the transparent disk and the light emitting array and blocks a predetermined ratio of light from the outside; Located under the transparent cover, the touch senses the touch and rub of a person from the outside, and generates a signal for controlling the rotational speed of the rotating means and the flashing frequency and the flashing time of the light emitting array to transmit to the controller module You may further comprise a sensor array.

In addition, it is preferable that the three-dimensional animation object is embedded in the transparent disk in a concentric circle or a spiral line.

On the other hand, it is preferable that the transparent disk is a crystal disk, and it is preferable that the three-dimensional animation object formed on the transparent disk is carved by laser internal engraving technique.

Preferably, the light emitter array is an LED array, and the transparent cover is preferably an acrylic plate coated with a light blocking thin film that blocks light corresponding to a main ambient light wavelength and transmits light corresponding to a wavelength of light emitted from the light emitter array. Do.

In addition, a heat radiation reflector for absorbing heat and reflecting light from the light emitter array may be provided to surround the light emitter array under the transparent cover.

3D animation display method according to the present invention for achieving the above object is to use the three-dimensional animation display device, the rotational speed of the rotation means and the flashing frequency of the light emitting array to satisfy the following equation (1) The module is controlled to implement a clear three-dimensional animation on the transparent disk.

[Equation 1]

(1) Rotational speed of rotation means (RPS) = blinking frequency of light emitting array (Hz) * angular distance between animation objects / 360 degrees

(2) Lighting time of the light emitting array = lighting ratio / blinking frequency of the light emitting array (Hz).

In this case, if there is a touch input from the touch sensor array, the flashing frequency of the light emitting array or the rotational speed of the rotating means is added to the 3D animation to move in the rotational direction of the transparent disk according to the direction and degree of touch. It is desirable to enable dimensional animation and interaction between viewers.

The device of the present invention has the advantage of being easy to manufacture and simple compared to the conventional general three-dimensional nip. Three-dimensional Zitrop consists of hundreds of animation objects, which require sophisticated work to place each one at a specific location in space, while the present invention uses a laser engraver or the like to simultaneously stamp a plurality of animation objects in a transparent disk. This saves effort and costs in production. In addition, in the present invention, since hundreds of fine animation objects are imprinted on the transparent disk without a support, it is possible to dramatically miniaturize the existing Zeplop. Therefore, it is possible to embed 3D animation inside everyday furniture, objects or building structures, and to enjoy clear 3D animation with little influence from ambient light. This is in contrast to traditional Zeplop, which is exposed to space, so you can only see 3D animations by darkening the surroundings. In addition, in the present invention, since the animation object can be imprinted and used in the transparent disk, a support is not necessary, and thus, three-dimensional animation composed of fine particles can be easily implemented. Thus, atypical objects such as clouds, fog, or nebulae can be represented in three-dimensional animation. When utilizing these features, the present invention may be utilized as a new visual information transmission medium that embeds educational, entertainment, or commercial three-dimensional animation content into everyday objects for people to enjoy.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following examples are only presented to understand the content of the present invention, and those skilled in the art will be capable of many modifications within the spirit of the present invention. Therefore, the scope of the present invention should not be construed as limited to these examples.

1 is a perspective view of a transparent disk as a main part of a three-dimensional animation display device according to an embodiment of the present invention. In this embodiment, crystal (crystal) was used as a material of the transparent body. Referring to FIG. 1, in the transparent disk 110, hundreds of three-dimensional animation objects 120 constituting each frame of the animation are disposed in the disk along concentric circles or vortices. The adjacent series of objects constituting the animation are arranged slightly differently and maintaining the same angular distance θ, which corresponds to each frame in the two-dimensional animation. Sub-Surface Laser Engraving (SSLE) technology is used to place animation objects in the transparent disk 110. An animation object is designed and placed in space using a 3D CAD program and imprinted on the transparent disk 110 using SSLE equipment. The animation object 120 is disposed on concentric circles or vortices according to the frame order.

2 is a partial front cross-sectional view of a three-dimensional animation display device according to an embodiment of the present invention, Figure 3 is a plan view of a three-dimensional animation display device according to an embodiment of the present invention. 2 and 3, a light emitter array 125 formed of a power LED is annularly installed around the transparent disk 110 so as to flash toward the animation object 120 in the transparent disk 110. The light emitter array 125 blinks at a frequency of, for example, about 70 to 90 Hz by an input provided from the light emitting control signal output line 190 to the controller module 400. Light emitted from the light emitter array 125 illuminates the animation object 120 in the transparent disk 110, and the image reflected in the A direction generates a three-dimensional animation image based on the principle of the afterimage of the eye. Rotating means 180 such as a motor rotates the transparent disk 110 at a constant speed. The tapered roller bearing 170 and the connecting portion 160 are positioned between the two parts to support the vertical load of the transparent disk 110 and to effectively transmit the rotational force of the rotating means 180. According to the angular distance between successive animation objects 120 imprinted on the transparent disk 110 and the blinking frequency of the light emitting array 125, the speed of the rotating means 180 is increased in the same manner as in Equation 1 below. Control to create three-dimensional animation. In addition, the lighting time is determined as shown in Equation 1 (2) according to the lighting ratio of the light emitting array 125, which changes the brightness and sharpness of the 3D animation.

[Equation 1]

(1) Rotational speed of rotation means (RPS) = blinking frequency of light emitting array (Hz) * angular distance between animation objects / 360 degrees

(2) Lighting time of the light emitting array = lighting ratio / blinking frequency of the light emitting array (Hz).

A series of animation objects 120 in the transparent disk 110 which are brightly illuminated by the light emitter array 125 at a frequency of 70 to 90 Hz are superimposed in the same space so that people can see the vivid three-dimensional animation with visual afterimage effects. . In order to obtain a clear animation image, it is preferable to search the optimal value for the lighting frequency and ratio of the rotating means 180 and the light emitting array 125 through experiments according to the implementation conditions.

On the other hand, because of the ambient light flashing the light emitter array 125 to the transparent disk 110, only the irradiation of light can not obtain a clear animation. Thus, the transparent disk 110 and the light emitting array 125 were embedded in a table top plate made of, for example, an opaque sidewall 302 and a bottom plate 304, and only the top surface of the table top plate was covered with a transparent cover 130. The transparent cover 130 is coated with a film that blocks a ratio of light from the outside, and the film blocks light corresponding to the wavelength of ambient light and transmits light corresponding to the wavelength of light emitted from the light emitting array 125. It is preferable that it is a transparent acrylic plate coated with a light blocking thin film. In this way, the transparent cover 130 reduces the reflection of the animation object 120 by the ambient light and emits the reflected light by the light emitted from the light emitting array 125 to generate a clear three-dimensional animation image. According to the implementation condition, a filtering film having an appropriate transmittance may be selected according to the brightness of the light emitting array 125 and the illuminance of the ambient light. The heat radiation reflector 150 absorbs heat from the light emitter array 125 to prevent failure of the light emitter array 125, and also reflects and blocks light emitted directly from the light emitter array 125 to the outside, thereby providing a clear three-dimensional animation image. It does not interfere with the creation of the. The heat radiation reflector 150 is installed to surround the light emitter array 125 under the transparent cover 130.

The touch sensor array 140 is located directly below the transparent cover 130 to detect contact and rub of a person from the outside, and to detect the rotational speed of the rotating means 180 and the flashing frequency and the flashing time of the light emitting array 125. Generates a touch sensor input signal to control and transmits it to the controller module 400 through the touch sensor input signal line 200, the controller module 400 receives the touch sensor input signal and the rotational speed and the light emitting array of the rotating means 180 The flashing frequency and the flashing time of the 125 are calculated and the power for the rotating means 180 and the light emitting array 125 are provided through the light emitting control signal output line 190 and the rotating means control signal output line 210 which are output cables. Pass each to.

The transparent disk 110, the rotating means 180, the light emitting array 125, and the power transmission component, which are components of the 3D animation display apparatus according to the embodiment of the present invention, are supported by the housing part. The housing parts can be everyday objects such as tables, lighting, walls, floors, furniture, and the environment. 4 illustrates an example in which a three-dimensional animation display device according to an embodiment of the present invention is embedded in a circular table. Referring to FIG. 4, the display device includes a table top plate formed of a transparent cover 130, sidewalls 302, and a bottom plate 304, a controller module 400, and a power and signal transmission cable 405. The table consists of a table top, legs 306 and a support 308 and most of the components of the animation device are embedded above the table top and legs 306. The controller module 400 has a power switch 410 connected to the power plug 420, but the power is turned on when watching the animation, otherwise it is turned off.

On the other hand, when the device is controlled in the above manner, it is possible to generate a lively three-dimensional animation that does not move in the rotational direction of the disc. FIG. 5 is an exemplary diagram for interaction between a 3D animation display device and a person through a touch sensor array in the 3D animation display device according to an embodiment of the present invention. Referring to FIG. 5, the controller module 400 may receive an input from the touch sensor array 140 to control the flow of animation. As shown in FIGS. 2 and 3, the touch sensor array 140 is positioned directly below the transparent cover 130 of the table top plate. As shown in FIG. 5, when the viewer's hand 500 rubs the table surface, the touch sensor array 140 is made in the touch sensor array 140. The signal is transmitted to the controller module 400 and adjusts the flashing frequency of the light emitter array 125 so that the animation moves in the rotational direction of the transparent disk 110 in proportion to the direction and width of the rub. This interaction makes the viewer feel as if they are moving the 3D animation by hand, making it more interesting to watch.
