We present a method that achieves advanced results for synthesizing novel views of complex scenes by optimizing an underlying continuous volumetric scene function using a sparse set of input views. Because volume rendering is naturally differentiable, the only input required to optimize our representation is a set of images with known camera poses.

• 1 Our algorithm represents a scene using a fully connected (nonconvolutional) deep network, whose input is a single continuous 5D coordinate (spatial location ( x , y , z ) and viewing direction ( θ, ϕ )) and whose output is the volume density and view-dependent emitted radiance at that spatial location.
• 2 We synthesize views by querying 5D coordinates along camera rays and use classic volume rendering techniques to project the output colors and densities into an image.
• 3 Because volume rendering is naturally differentiable, the only input required to optimize our representation is a set of images with known camera poses.
