  Virtual Reality, and Extended Reality in general, connect the physical body
with the virtual world. Movement of our body translates to interactions with
this virtual world. Only by moving our head will we see a different
perspective. By doing so, the physical restrictions of our body's movement
restrict our capabilities virtually. By modelling the capabilities of human
movement, render engines can get useful information to pre-cache visual texture
information or immersive light information. Such pre-caching becomes vital due
to ever increasing realism in virtual environments. This work is the first work
to predict the volume in which the head will be positioned in the future based
on a data-driven binned-ellipsoid technique. The proposed technique can reduce
a 1m3 volume to a size of 10cm3 with negligible accuracy loss. This volume then
provides the render engine with the necessary information to pre-cache visual
data.
