<font><font face="verdana,sans-serif">I guess you have to recompile the changed VTK. But I don't get the point of implementing multiplication of 4x4 matrix in CUDA. 4x4 matrix is too small to get a benefit of GPGPU, unless you plan to multiply is thousands or millions of times.<br>

i wanna know since vtk is open source could i add a new classe or derive a<br>
sub classe from the exicting one or even change the code of some classes;<br>
how to do that please<br>
<br>
i am tryed to do that :<br>
- i chosed classe called vtkMatrix4x4 and make copie and rename it to<br>
vtkMatrix4x4cu<br>
- i did some changes and add the header and the c++ file in my project<br>
- the vtkMatrix4x4 is used in vtkCamera classe so i replace it with my<br>
vtkMatrix4x4cu<br>
-when i complie the project it give me Link error<br>
I belive that vtkMatrix4x4 when the first time i build vtk was intgrated on<br>
vtkCommon.lib<br>
so please tell me how do i fix that<br>
