GuidableDeltaMush

Only in Wrap4D

GuidableDeltaMush is similar to DeltaMush, but rather than using a reference geometry, it predicts high frequency details for new expression by number of example expressions.

Tip

This node can increase the resolution of input mesh using high resolution FACs.

Inputs

Input Geometry: Geometry Geometry to be deformed
Neutral Geometry: Geometry Neutral geometry, in same topology as Input Geometry

Output

Geometry Predicted DeltaMush for Input Geometry

Parameters

Auto-Compute:

if set, the node will be recomputed each time some parameter or input data is changed

Compute:

if Auto-Compute is off, starts DeltaMush predicting process

Sync View:

if set, synchronize left and right viewports inside the Visual Editor

Smooth Input Geometries:

if set, smoothes Input Geometry and Neutral Geometry

Input Smoothing Type:

Uniform: consider weights to be equal
Edge Length: weights depend on edge lengths

Input Smoothing iterations:

number of smoothing iterations

Input Smoothing step size:

smoothing factor

Train Parameters tab

Note

To predict DeltaMush for Input Geometry you need high resolution FACs (Detailed Blendshape Reference Meshes) and corresponding low resolution FACs (Simplified Blendshape Reference Meshes) in same topology as Input Geometry. In order for the result to be the best, low resolution FACs and Input Geometry should be in the same detail space. You can use Visual Editor to compare input geometries and low resolution FACs.

Note

To check the size of the sampled patches use Visual Editor Tab. The smaller the patches, the more accurate will the predicted DeltaMush be, but it would need more time to compute.

Show Patches:: if set, shows sampled patches inside the Visual Editor
Polygroup Blur Iterations:: number of iterations while blurring patches
Patch Blur Weight (cm):: average adjacent weight on every iteration while blurring patches
Sample Radius (cm):: radius of samples, which become patches
