![]() This is not surprising, since the most general two-dimensional rotation consists. To do this, you’ll need to convert the vector to polar coordinates (radius + angle), adjust the angle, and the convert it back to cartesian to solve for the components (x and y). were to rotate any vector v, the end result would still be eq. Here is my function to transform a 2D vectors components under rotation. If you wanted to rotate that point around the origin, the coordinates of the new point would be. the effect of rotating a vector from the origin to some arbitrary point. ![]() I dont know much about the mathematical side of programming. There are directx functions for rotating 3d vectors but I couldnt find any for 2d vector rotation. The question of how to rotate a PVector object (the data of the vector itself, I’m not talking about rotating while drawing) came up in my nature of code course yesterday. 2D rotation is represented solely by its angle in counterclockwise direction and rotation transformation can be created by calling Translation. The two dimensional rotation matrix which rotates points in the xy plane. Im making a 2d game in directx and need a function to rotate a 2d vector(D3DXVECTOR2).
