Skeletons and animations can also be imported from other project files. Spine can import data in its JSON or binary formats, which enables a path to import data from other tools into Spine. Spine can also export animated GIFs, PNG or JPEG image sequences and AVI or QuickTime video.
Spine exports animation data in its own, documented JSON and binary formats which are ideal for use with the Spine Runtimes.
Posing a character with images that can bend becomes as easy as just positioning the bones. When the bones move, the vertices move with them and the mesh is deformed automatically. Weights (often called "skinning") allow individual vertices in a mesh to be attached to different bones. FFD allows meshes to stretch, squash, bend and bounce in ways that aren't possible using rectangular images. Meshes also enable FFD and skinning.įree-Form Deformation (FFD) allows you to move individual mesh vertices to deform the image. This improves the fill rate because pixels outside the polygon won't be drawn, which is especially important for mobile game. Instead of drawing rectangles, meshes allow you to specify a polygon inside your image. It provides a detailed view of all the timelines that make up an animation and allows fine adjustments to be made to the animation's timing. The dopesheet is at the heart of animating. Beyond the many editor features described below, the live demos for the Spine Runtimes show how animations can be layered and blended to achieve all kinds of dynamic behavior. Spine is packed with features to keep you productive while building great looking animations. Spine is dedicated to 2D skeletal animation, providing an efficient workflow both for creating amazing animation and for integrating it into your games. We believe creating great 2D animation requires not only powerful software, but a powerful workflow.
