Vector3 Cross Operation for CLI/C++

Posted Tuesday, 21 December, 2010 - 21:26 by LikeTK in 
Vector3^ v1= gcnew Vector3(0, 2.0f, 1.0f);        
Vector3^ v2 = gcnew Vector3(0, 1.0f, 0.0f);          
Vector3^ v3 = Vector3::Cross(v2, v1);

error C2665: 'OpenTK::Vector3::Cross' : none of the 2 overloads could convert all the argument types

Any feedback

Vector3 v1= gcnew Vector3(0, 2.0f, 1.0f);        
Vector3 v2 = gcnew Vector3(0, 1.0f, 0.0f);          
Vector3^ v3 = Vector3::Cross(v2, v1);   //This is OK

But 

Vector3 v1= gcnew Vector3(0, 2.0f, 1.0f);        
Vector3 v2 = gcnew Vector3(0, 1.0f, 0.0f);

error C2440: 'initializing' : cannot convert from 'OpenTK::Vector3 ^' to 'OpenTK::Vector3'

Is there something I can do to Re-Compile the source code to make the Cross method to take 

Vector3 Cross( Vector3^ v1, Vector3^ v2)

There are two overloads:

Vector3 Cross(Vector3 v1, Vector3 v2)
void Cross(ref Vector3 v1, ref Vector3 v2, out Vector3 result)

You are trying to use this:

Vector3 Cross(ref Vector3 v1, ref Vector3 v2)

but there is no such signature, because the CLS prohibits overloads on reference specifiers. Use the overload with the out parameter instead.

Thanks, I figure out the problem through your feedbacks.
