Two of the most used viewers for 3D virtual reality grids are Firestorm and Singularity. We are not going to recommend either as that is solely up to each persons individual preferences. Both work well in Virtuality though each has their own qualities that make them different. If you are completely new to virtual reality, we suggest trying each to learn the differences so you will be able to make a well informed choice according to your preferences and how easily you are able to navigate through each program. If you need help once you are logged in, any staff member can help you to learn the viewer and some basic things you will need to get around inside the grid.
