Returns the opacity for a position. Used primarily by the occupancy grid. Args: positions: the positions to evaluate the opacity

Takes in a Ray Bundle and returns a dictionary of outputs. Args: ray_bundle: Input bundle of rays. This raybundle should have all

compute output of ray samples

Computes and returns the colors. Returns output field values. Args: ray_samples: Samples locations to compute outputs.

run the model with additional inputs such as warping or rendering from unseen rays Args: ray_bundle: containing all the informatio

Render segmentation with foreground model for mesh culling.

Get global rank of current thread

Utility function to read segmentation from the given filepath If no mask is required - use mask_indices = []

Returns a function that returns the density of a point. Args: origins: Origins of rays directions: Directions of rays

Compute the total variation loss for the feature volume.

This function gets your training loss dict. This will be responsible for getting the next batch of data from the DataManager and interfacing w

Get a tree from a node class. This allows one to do tree["path"]["to"]["node"] and it will return a new node if it doesn't exist or t

Find which values are present in a list and where they are located

Get the version of the viewer.

Return path to vocab tree. Downloads vocab tree if it doesn't exist. Returns: The path to the vocab tree.

Perform reconstruction using the already-created target_dir/images.

! Generates V = buffer * 10^decimal_exponent, such that M- <= V <= M+. M- and M+ must be normalized and share the same exponent -60 <= e <= -32. */
