3D动画之,骨骼动画(skeletal animation) - 完 关键帧动画(keyframe animation)在3D中很大的一个缺点是占用的数据量比较大,如果动画衔接需要更细致一些、自然一些,那么要加入的关键帧就更多。但是,对于关键帧动画来说,每一帧的顶点数量是固定的。所以,对稍微复杂的模型,每加入一帧,就意味着又加入那么多的顶点。解决...

Skeletal animationis a technique incomputer animation, particularly in the animation ofvertebrates, in which a character is represented in two parts: a surface representation used to draw the character (called theskin) and a hierarchical set of bones used for animation only (called theskeleton). T...
相对于Keyframe animation ,Skeletal animation的思想是将有动画的物体分为两个部分:用于渲染的Mesh 和 用与运动的骨骼(通常称为skeleton或者rig)。Mesh上的顶点和骨骼通常存在着一对多的对应关系,当骨骼发生transform的变化的时候,Mesh上的顶点会根据对应关系得出新的位置。 在游戏引擎架构这本书中,一个很有用的思想...
人体动画是电子游戏的重要组成部分,而其中最重要的技术之一就是骨骼动画skeletal animation 想象我们有一个人形的模型,我们要如何使它动起来? 我们最先想到的应该就是像移动一个固定的box一样移动整个模型,显然这一点也不自然。 生物可以想象成一个铰链结构,每个组成部分都是可以独立移动的。最简单的移动铰链结构的方式...
Pre-baked Skeletal Animation System The overriding purpose of this system is performance, so some of the sacrifice of expressiveness is considered acceptable. We have targeted a number of underlying optimizations, and the current runtime flow is roughly as follows: ...

Skeletal animation is a processor-efficient and relatively simple animation system that can simulate any jointed object, from people to insects to machinery. The titular skeleton is a hierarchy of jointed but individually rigid bones that are manipulated in the same way as a real skeleton. Vertice...
With skeletal animation each character is a hierarchy of bones( ie. skeleton ), and the bones control the deformation of the character mesh. What follows is an quick overview of one way to handle skeletal animation, based on a much simplified version of how I do it in my own program. ...
2.1 Skeletal Animation DirectMesh v2.0 will use skeletal animation as it's primary form of frame-based movement. Skeletal animation is based on bones, which are in turn connected to individual vertices. These vertices act as a "skin" on top of the bones. ...
