TemporalSmoothing

Only in Wrap4D

Smoothes a sequence Geometry using information of nearest frames. The positions of each vertex of the new Geometry are smoothed based on information about neighbor frames. Can be computed multiple times, using neighbors of neighbor and so on.

This node was previously available as a Temporal Smoothing Tool.

Inputs

Reference geometry

Geometry (multiple) Topology, transform and visual params donor

Mask

VertexMask (optional)

A vertex mask that defines a smoothing ratio for each vertex.

Output

Geometry Smoothed geometry

Parameters

File Name:

a sorce file path mask to load from. Supports Path Interpretation, must contain # symbols.

Method:

smoothing method: Linear, Linear with Average Ratio, Gaussian.

Neighbors:

number of frames in both directions which will affect the current frame

Iterations:

number of iterations of temporal smoothing algorithm. Increases number of frames required for computation

Averaging Strength:

smoothing strength for Linear with Average Ratio method.

Gaussian Sigma:

smoothing strength for Gaussian method.

Frame:

scripted frame number, by default equals to the current frame number (starts from zero).

Note

At least Neighbors * Iterations Geometries are needed on one side of a frame to compute it.

How to specify a mask

In order to specify a file mask, replace sequence digits in a file path by a hash symbols #.

If your folder structure is simple (for example, D:/CapturedData/Frame0001.obj), you may select a single file using a file dialog. In that case, a tool will try to convert it to a required mask and fill range values automatically.
