[fixed]quaternion::rotationFromTo() wrong

[takamoto]

Isn't this wrong?

Code: Select all

 
    else if (d <= -1.0f) // exactly opposite
    {
        core::vector3df axis(1.0f, 0.f, 0.f);
        axis = axis.crossProduct(v0);
        if (axis.getLength()==0)
        {
            axis.set(0.f,1.f,0.f);
            // axis.crossProduct(v0); // wrong
            axis = axis.crossProduct(v0); // correct
        }
        // same as fromAngleAxis(core::PI, axis).normalize();
        return set(axis.X, axis.Y, axis.Z, 0).normalize();
    }

Thanks, calling crossProduct without using the result does indeed not make sense. It's fixed now in svn release branch 1.8 in revision 4583. Will be merged with trunk soon.
