tfg.rendering.volumetric.ray_radiance.compute_radiance

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

Note:

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

rgba_values A tensor of shape [A1, ..., An, N, 4], 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, 3] for the estimated rgb values, a tensor of shape [A1, ..., An, 1] for the estimated density values, and a tensor of shape [A1, ..., An, N] for the sample weights.
