I was trying to create a simple tool for volume rendering of medical images using VTK for Python, but currently the issue I am facing is that the volume render does not look visually appealing (when compared to similar tools implemented in unreal engine). I have tried using vtkOspray and its path-tracing algorithm gave the required visual appeal, but it was so slow and not suitable for real time rendering. I have also tried using vtkAnari pass through which multiple backends were used and even adding raytracing support using VisRTX didn’t show much of an improvement over VTK’s native rendering. But path-tracing using backends such as Barney gave me the required output (but it was not suitable for real time render). Are there any other methods that I can use for improving the visual appeal of volume rendering in VTK Python?
