Reply To: Reversed Magnus effect

[Martins.Brics]

Hi Robin,

sorry for long not response. After vacation I had to deal with another project.

But I finally understood why the effect suddenly disappeared. I changed the ration matrix from

rotationMatrix[0] = cos;
rotationMatrix[1] = -sin;
rotationMatrix[2] = sin;
rotationMatrix[3] = cos;

to

rotationMatrix[0] = cos;
rotationMatrix[2] = -sin;
rotationMatrix[1] = sin;
rotationMatrix[3] = cos;

and forgot that I did the changes. Changed indicis [1]->[2] and [2]->[1]. This is equivalent to rotation by negative angle. In version 1.4 I have to change to do the same trik in order not to observe visually reversed Magnus effect.
