A method and terminal for generating animation curves

Abstract

The invention provides a method for generating an animation curve and a terminal. The method comprises the steps of acquiring at least four control points, generating a curve pattern according to the at least four control points, acquiring the number of preset animation output points, determining the coordinate values of each preset animation output point on the curve pattern, and determining that the animation curve control terminal is controlled to display the curve pattern as an animation curve according to the coordinate values when the variation state of the preset animations displayed by a curve pattern control terminal conforms to the variation state of preset standard animations, wherein the variation state of the preset animations, displayed by the control terminal, conform to the variation state of the preset standard animations. The at least four control points are composed of two control points used for respectively controlling the generation of the start end and the tail end of the curve pattern, and at least two curvature control points used for controlling the generation of the curve pattern at different curvatures. The first and second coordinate axes of the curve pattern respectively correspond to a time coordinate axis and a variation-degree coordinate axis for an animation curve pattern control terminal to display preset animations.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and terminal for generating animation curves. Background technique [0002] At present, when the animation displayed on the terminal needs to change, it will proceed from the animation start change state to the animation end change state, and the process from the start change state to the end change state of the animation is controlled by the animation curve running through the terminal background. A general animation curve is a curve formed by various nonlinear change functions encapsulated in an interpolator. Through the change values ​​defined by different functions, the change rules (such as acceleration and deceleration, etc.) relative to the time change value are determined. For example, when the interface of the terminal is switched, the transition from the interface before the switch to the interface after the switch is realized through animation, and the animatio...
