It would be nice to have a Vector3 function that rotates it towards another Vector3, restricted to a maximum rotation delta. This exists in Unity, and it's very handy since it's kind of hard to do on your own.

What i need to do is to randomly choose 2 elements of each row (but not the ones and the zeros) and rotate the vector in between them . For example new_n= [ 1,19,15,17,3,7,2,16,10,21,18,6,1; 1,14,13,4,8,20,9,5,1,0,0,0,0; 1,12,11,1,0,0,0,0,0,0,0,...

实际上完成的就是A ->A'->A"->A"'->A ,实现四个区域的替换。所以外层循环从0~matrix.size()/2, 内层循环根据对角线从i ~ matrix.size() - i -1。 代码实现如下: class Solution { public: void rotate(vector<vector<int> > &matrix) { int n = matrix.size(); for(int i = 0; i < ...
It will give you the homogeneous coordinate transformation matrix, M, of the rotation. So, if the equation for the plane to be rotated in homogeneous coordinates is, [a,b,c,d]*[x;y;z;1]=0 then the rotated equation vector for the plane will be ...
4. How to Rotate a Shape in PhotoshopNow let's see how to rotate a shape in Photoshop. If you want to rotate a vector shape, and you're wondering if it's possible to rotate it without losing the stroke or other properties, don't worry—the Free Transform Tool doesn't affect them ...
