tfg.rendering.volumetric.ray_density.compute_density

Renders the density values (alpha) for points along a ray, as described in "NeRF Representing Scenes as Neural Radiance Fields for View Synthesis".

tfg.rendering.volumetric.ray_density.compute_density(
    density_values, distances, name=None
)

In the following, A1 to An are optional batch dimensions.

density_values A tensor of shape [A1, ..., An, N, 1], where N are the samples on the ray.
distances A tensor of shape [A1, ..., An, N] containing the distances between the samples, where N are the samples on the ray.
name A name for this op. Defaults to "ray_radiance".

A tensor of shape [A1, ..., An, 1] for the estimated density values, and a tensor of shape [A1, ..., An, N] for the sample weights.
