When it comes to true accuracy in regards to the visualization of your data, you can only trust the robustness of ray tracing. These methods yield true quality images like those seen in Hollywood’s movies as well as extremely complex numerical simulations.
Ray-tracing methods are often much slower computationally than other visualization methods, but they represent the most realistic and accurate visualization of data that can be produced. The resulting images often look very realistic depending upon the rendering methods applied to the data.
