<h2>Method<a class="headerlink" href="#method" title="Permalink to this heading">#</a></h2>
<p><img alt="method overview" src="https://jkulhanek.com/tetra-nerf/resources/overview-white.svg" /><br>
The input to Tetra-NeRF is a point cloud which is triangulated to get a set of tetrahedra used to represent the radiance field. Rays are sampled, and the field is queried. The barycentric interpolation is used to interpolate tetrahedra vertices, and the resulting features are passed to a shallow MLP to get the density and colours for volumetric rendering.<br></p>
