Animation Technology-keyframe) Key Frames are a commonly used animation technology. The basic principle is to extract key frames from the animation sequence, and other frames are computed by interpolation of these key frames based on time. A simple key frame structure: Typedef struct skeyframe {DWORD time;D3dmatrix ma

Similar to from/to/by animations, Keyframe Animations can also animate the target property values in an animated form. Unlike from/to/by animations, from/to/by animations only control changes between two states, while keyframe animations can vary between states, for example, for the previous example of changing the width of a button, if we want to achieve the following effect: Change width from 0 t

In CSS3, we can create keyframe animation effects through @keyframes. We need to bind the @keyframes to the selector, otherwise no effect will occur. Also, we need to define the animation duration and animation name Grammar @keyframes Animationname {keyframes-selector {css-styles;}} value Descriptio

// KeyP Ath: attribute name of CAlayer. Not all attributes are allowed. You can modify attributes of an animation only when the animation attribute appears in the header file, for example, bounds. size // CALayer CABasicAnimation * basic = [CABasicAnimation animationWithKeyPath: @ "bounds"]; [basic setDuration: 2]; // 2 modify the attribute value basic. fromValue = [NSValue valueWithCGRect: CGRectMake (0,
