I am tired of 2D plots or Vised software, so I am looking for a software for 3D plots. I'm not looking for very complex/efficient things (such as computer scheme translation into MCNP language) just something reliable and straightforward.
Thanks for your answer, but the software you use cannot be used for MCNP. My question was perhaps not clear enough. I'm looking for a software able to read the MCNP code and translate it into 3D geometry visualization. (MCNP is a Monte Carlo code to simulate the particule transportation into matter).
You're definitively right. Vised is one of the sofware which can be used to visualized MCNP geometry. Unfortunaly, I experience a LOT of crashes with it when I include my input in it. And when it doesn't crash, the 3D result itself is often very buggy.
