Animation button device based on a parameter, and display method

Abstract

The invention discloses an animation button device based on a parameter, and a display method. The method comprises the steps of i, judging a sequence type of an animation when the animation is played, entering a step ii if the animation is a parallel animation, and entering a iv step if the animation is a serial animation; ii, in the parallel animation, calculating the highest common divisor of motion intervals of multiple variables as a synchronous reference interval; iii, calculating the actual motion step size and required motion times of each variable under the reference interval calculated in the step ii; and iv, carrying out a corresponding single-time parallel, or repeated parallel or reciprocated parallel, or single-time serial, or repeated serial, or reciprocated serial animation process according to the type of the animation. According to the method and the device, the operation difficulty of establishing compound and animation sequences by a user is reduced, the animation types and sequences are completed, and a dynamic geometric animation function is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of dynamic geometry application software, in particular to a parameter-based animation button device and display method. Background technique [0002] The application software based on dynamic geometry is mainly used as teaching aid software for mathematics, physics and other science subjects; the animation control button among them achieves the effect of dynamically displaying the unchanging geometric properties between graphic elements by controlling the change of parameters. For example, the range of parameter u000 is 0-1, and its value controls the position of a semi-free point on a line segment (it can be the ratio of the distance from the point to the starting point of the line segment to the length of the line segment); The coordinate points represented by , etc., are constrained by different variables to constrain their geometric positions. Existing animation buttons usually specify the name of the ...

AI Technical Summary

Problems solved by technology

[0003] Disadvantages of the prior art: 1. An animation button can usually only control one variable, and complex combined animation cannot be easily realized: if multiple geometric elements need to be controlled at the same time, these geometric elements must be associated with the same variable. Increased difficulty of use

2. The start value, end value, number of motions, and motion frequency of the animation are all set to specific values, which cannot be dynamically modified; nor can it complete the data iteration commonly used in mathematics; 3. The animation type is single: the default is one motion, that is, from the start The initial value moves to the end value according to the preset number of movements and frequency; the animation sequence, movement direction, etc. cannot be realized
