animation - how do I apply a wieght to a bone?

Question

If I were to assign every vertex to a bone/matrix, how would I edit the transformation matrix so some of the vertexes are transformed less?

For example, if I have the matrix

cos sin  0 0
-sin cos 0 2
0    0   1 0
0    0   0 1

What do i do to it to make the vertex rotate less?

Answer 1

引用 paddy “那些 sin 和 cos 项都应该提供一个角度。例如 sin(theta)。所以，既然你最有可能控制它，那就减少角度。” 因此，通过乘以一个值 -1 到 1 来改变角度，这将改变它改变的方向/数量。
