Ramjet
Ramjet est un moteur d'animation JavaScript et une bibliothèque de morphing d'éléments DOM. Il fonctionne comme un utilitaire de transition qui anime les mouvements et les dimensions entre différents éléments HTML pour créer des changements visuels entre les états d'interface.
La bibliothèque se spécialise dans le morphing d'éléments cross-tree, ce qui lui permet d'animer la position et les dimensions d'un élément pour correspondre à un autre, indépendamment de leur emplacement relatif dans la hiérarchie du document. Elle y parvient en calculant les offsets visuels et en utilisant un mécanisme de clonage personnalisable pour créer des proxies visuels temporaires.
Le système gère le mouvement organique via des fonctions de timing personnalisées et des courbes d'accélération. Il coordonne ces transformations en utilisant des translations accélérées par le matériel et un contrôle de visibilité basé sur l'opacité pour effectuer la transition des éléments sans déclencher de reflow de mise en page du navigateur.
Features
- Element Transitioning Mechanisms - Provides a comprehensive system for animating the movement and size of DOM elements as they transition between states.
- JavaScript Animation Libraries - Functions as a high-performance JavaScript engine for driving organic movement and interface transitions.
- UI Element Bounding Boxes - Calculates visual offsets between elements to drive precise spatial transformations.
- DOM Node Manipulators - Implements a cloning mechanism to create temporary visual proxies for animating elements across the document tree.
- DOM Node Transition Utilities - Provides utilities to clone and morph elements, enabling seamless visual shifts across the document tree.
- CSS Transform Animations - Uses hardware-accelerated CSS transforms like translate and scale to animate elements without triggering reflows.
- Cross-Tree Element Pairing - Pairs elements for transition regardless of their nested position in the document hierarchy using unique identifiers.
- Dynamic Layout Morphing - Smoothly slides and resizes elements to morph the page layout from one configuration to another.
- Cross-Tree Morphing - Specializes in morphing the position and dimensions of elements regardless of their relative location in the document hierarchy.
- Visual Element Morphing - Animates transitions between DOM elements by calculating visual offsets and morphing their dimensions.
- Visual Offset Morphing - Calculates visual offsets to animate the transition of one element into the position and dimensions of another.
- Easing Functions - Applies mathematical easing curves to coordinate the acceleration and deceleration of spatial transformations.
- Animation Easing Functions - Implements mathematical timing functions to control the acceleration and deceleration of element transformations.
- Smooth Animation Interfaces - Creates fluid, organic visual transitions between interface states to enhance the overall user experience.
- Customizable Node Cloning - Allows developers to control how nodes are duplicated by excluding specific attributes or subtree depths.
- Transition-Aware Cloning - Provides customizable cloning that allows excluding specific attributes or children to ensure smooth transitions.
