Thank you so much for your answer,<br>i already the vtk classes and i need your help about the vtkVolumeRayCastMapper class to understand the exact algorithm and acceleration techniques it implements. I read in 'the visualization toolkit' book that the class uses depth buffer (PARC) algorithm, but i have the 2nd edition of the book. Thus, could you tell me if i am right and if there's a paper or a publication i theoretically can refer to?
