  Immersive, stereoscopic viewing enables scientists to better analyze the
spatial structures of visualized physical phenomena. However, their findings
cannot be properly presented in traditional media, which lack these core
attributes. Creating a presentation tool that captures this environment poses
unique challenges, namely related to poor viewing accessibility. Immersive
scientific renderings often require high-end equipment, which can be
impractical to obtain. We address these challenges with our authoring tool and
navigational interface, which is designed for affordable head-mounted displays.
With the authoring tool, scientists can show salient data features as connected
360{\deg} video paths, resulting in a "choose-your-own-adventure" experience.
Our navigational interface features bidirectional video playback for added
viewing control when users traverse the tailor-made content. We evaluate our
system's benefits by authoring case studies on several data sets and conducting
a usability study on the navigational interface's design. In summary, our
approach provides scientists an immersive medium to visually present their
research to the intended audience--spanning from students to colleagues--on
affordable virtual reality headsets.
