我在做仿3D转面时就思考过，要是每个网格点上的透视权重是可以通过关键帧来控制权重分配的话，那转面效果会更接近真实3D的透视感。比如一个球面的中线，它会在最中心的时候权重影响最大，越到边缘的时候权重影响越小，当我一直向左移动骨骼时，点就不会无限往左移动，而是会在一个正确的位置慢慢停下，这样我就可以用一个骨骼对球面实现上下左右更真实更大角度的旋转而不用切换切片和骨骼。这个思路是否是可行的？
后续更新有给权重打关键帧的计划吗？
林汤圆 I guess this is not exactly what you are looking for, but we have been wanting to add joystick-style controls to the Spine editor for some time. We have mentioned this in the following thread:

We're still working on improvements for Spine 4.2, and since we plan to focus on streamlining the workflow in 4.3, I don't think we'll be adding such a big new feature right away. That said, it's something we're keeping in mind for future updates.
