FusedRF: Fusing Multiple Radiance Fields
Rahul Goel Dhawal Sirikonda Rajvi Shah PJ Narayanan
Radiance Fields (RFs) have shown great potential to represent scenes from
casually captured discrete views. Compositing parts or whole of multiple
captured scenes could greatly interest several XR applications. Prior works can
generate new views of such scenes by tracing each scene in parallel. This
increases the render times and memory requirements with the number of
components. In this work, we provide a method to create a single, compact,
fused RF representation for a scene composited using multiple RFs. The fused RF
has the same render times and memory utilizations as a single RF. Our method
distills information from multiple teacher RFs into a single student RF while
also facilitating further manipulations like addition and deletion into the
fused representation.
