Description

Detailed Description of the Invention: Industrial Application Field The present invention logically interrupts the flow of a series of animations by simultaneously performing interpolation settings by specifying key frames for the environment and interpolation settings by specifying key frames for figures. This invention relates to an animation editing device that performs animation at high speed by simply registering a single animation as a single animation without drawing, and by instructing primitives not to be drawn in each frame and having the drawing device draw only the necessary figures. be.

BACKGROUND OF THE INVENTION An example of animation editing means of a conventional animation editing device will be described below with reference to the drawings.

14 is an editing device, 14 is a picture designation memory, 15 is a viewpoint setting memory, 16 is a light source setting memory, 17 is an animation control device, and 18 is a drawing device.

Further, FIG. 4 shows a configuration diagram of another conventional animation editing device. In FIG. 4, 20 is an input device, 21 is an editing device, 22 is an environment specification memory, 23 is a graphic data memory, 24 is an animation control device, 2
5 is a drawing device.

The operation of the animation editing device configured as described above will be described below.

In FIG. 3, the input device 12 collects a group of data called a picture consisting of the shape, size, position, etc. of figures included in a still frame displayed during a certain period, as well as the type and intensity of the viewpoint and light source. Enter data such as location.

Via the editing device 13, the picture data is stored in the picture designation memory 14, the time series data of viewpoints is stored in the viewpoint setting memory 15, and the data of the negative set of light sources is stored in the light source setting memory 16. Each piece of viewpoint time series data corresponds to viewpoint data at a key frame time designated by the user.

It is also possible to create the graphic data included in the picture in advance and to specify the name or identification number of the picture in the picture designation memory 14.

The animation control device 17 retrieves the type of conversion from the viewpoint setting memory 16, temporally interpolates data of discretely set time-series viewpoint positions, and calculates the viewpoint at each frame time point. The animation control device 17 stores the resulting viewpoint at each frame point and the picture designation memory 14.
The figure to be displayed taken out from the light source setting memory 16
The type 9 position 9 intensity of the light source, etc. are output to the drawing device 18 according to a preset frame time interval. The drawing device 18 draws a figure to be displayed according to the viewpoint and light source settings and outputs it to a display device or an image memory.

In addition, in FIG. 4, environmental data regarding the viewpoint, light source, etc., and graphic data such as the shape, size, and position of the graphic to be displayed are inputted from the input device 2o, and the environmental data is stored in the environment setting memory 22. In the figure data memory 23,
It is stored via the editing device 21.

The animation control device 24 includes a graphic data memory 23
Time-series graphic data set discretely for each key frame time is taken out from , and interpolated in time to calculate the position and size of the graphic at each frame time.

The animation control device 24 outputs the resulting graphic data at each frame point and the viewpoint and light source data retrieved from the environment setting memory 22 to the drawing device 26 according to preset frame time intervals. The drawing device 25 draws a figure to be displayed according to the viewpoint and light source settings and outputs it to a display device or an image memory.

Problems to be Solved by the Invention However, in the above configuration, in the first example,
Only the viewpoint changes in a series of animations,
If the light source data is changed or the type of figure included in the picture is changed or moved, it is necessary to edit the animation again and register and connect it as a separate series of animations.

Next, in the second example, it is possible to change the type and size of the shapes displayed in a series of animations, but the drawing environment such as the viewpoint and light source is fixed, and to change them, you need to edit the animation separately. You must register and connect as .

In this way, animations that are originally semantically coherent are cut off, and it takes a lot of effort to set up, so
There was a problem in that it had to be possible to register the animation continuously as a series of animations.

For this reason, there is a problem in that high-speed performance is impaired because visibility is determined for all the graphics stored in the graphics data memory.

Therefore, when the type of figure used is constant, if you want to temporarily hide the figure without removing it, you cannot specify that it will not be displayed, so move it to a position where it cannot be seen from the display screen. It was necessary to do so.

In view of the above-mentioned problems, the present invention inputs the drawing environment such as the viewpoint and light source and the displayed figures as objects in animation as time-series data set discretely for each key frame.

By interpolating at pre-specified time intervals, changes in the type of coordinate transformation, changes in the viewpoint position, changes in the type, position, and intensity of the light source, and changes in the type, size, and position of the displayed figures can be kept constant. By editing, it can be registered as a series of animations, and by registering invisible as solid usage information in the shape object attribute memory, shapes that are not displayed can be saved, visibility determination can be omitted, and the shape can be saved in the environment object attribute memory. The present invention provides an animation editing device that performs high-speed animation by saving unused environments and omitting environment settings by registering non-use as usage information of environment data.

Means for Solving the Problems In order to solve the above problems, the animation editing device of the present invention uses interpolation information such as graphic object data, environment object data, interpolation method, key frame time, and temporal interpolation timing. an input device for inputting or editing data; a graphic object attribute memory that stores a specified key frame time, graphic data to be displayed at that time, and activation information for determining whether the graphic is visible;
An environment object attribute memory that stores the specified key frame time, environment data to be changed at that time, and activation information that determines whether the environment is used; an editing device including a display section for displaying and writing the data into a graphic object attribute memory and an environment object attribute memory for editing, a drawing device that draws a graphic under a specified drawing environment, and a graphic object attribute memory. Reads keyframe graphic object data and environmental object data whose characteristics are captured at discrete times from the environmental object attribute memory, interpolates them temporally, and outputs the graphic data necessary for environment settings and display to the drawing device for each frame. It is equipped with an animation control device.

Effect of the present invention With the above-described configuration, by specifying a key frame and inputting environmental object data and graphic object data such as viewpoints and light sources, changes in viewpoints, light sources, and graphics at each frame point are internally and temporally controlled. By interpolating and drawing, you can easily register a group of connected movements as one animation, and objects that do not need to be displayed at each frame can be stored as invisible or unused as usage information. By omitting the determination by the drawing device, a series of animations can be made faster.
