All depends on how elaborate you want that walkthrough to be. For example, you could create Quicktime VR files in Vue (360 panoramas) and edit them with a QTVR editor to link them together with hotspots (I have never done that but I guess it should be possible). That would give you the equivalent of games such as Riven. If you want simple walthrough with basic shading and lights, VRML should be ok. If you want more elaborate shading, textures and effects (reflection, transparency, etc), you will have to chose a rendering engine and create a file to open in that engine. Typically, you would do that with games such as Unreal, HalfLife or Quake, and their corresponding editor. The advantage is that you can go pretty far in realism with these editors. The problem is that viewing the final file requires to have that game engine installed.
