GuidableTexture

Only in Wrap4D

GuidableTexture is an example-based texture generating method that can predict new texture for new type of expression using the example expressions.

Inputs

Input geometry

Geometry New expression geometry to predict texture for

Neutral geometry

Geometry Neutral geometry, in same topology as Input Geometry

Output

Image Predicted texture 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 texture predicting process

Train Parameters tab

Neutral Reference Mesh:

a file name of Neutral Reference Mesh

Blendshape Reference Meshes:

a list of file names of Blendshape Reference Meshes

Neutral Reference Texture:

a file name of Neutral Reference Texture, correspondent to Neutral Reference Mesh

Blendshape Reference Textures:

a list of file names of Blendshape Reference Textures, correspondent to Blendshape Reference Meshes

Reload:

forces to reload geometries and textures from Neutral Reference Mesh, Blendshape Reference Meshes, Neutral Reference Texture and Blendshape Reference Textures

Mesh Segmentation Parameters tab

Note

To check the size of the sampled patches use Visual Editor Tab. The smaller the patches, the more accurate the predicted texture will be, but it at a cost of increased computation time.

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

Save Weights tab

Note

For advanced users there is an option to save texture blending weights per vertex to JSON. JSON arranged like a dictionary, where the key is texture file full name (file path from the root) and value is a vector of weights (float value from 0.0 to 1.0) per vertex.

Save Per Vertex Weights to JSON:

if set, will automatically save blending texture weights per vertices to json

Create Intermediate Directories:

if set, nonexistent directories in the file path will be created

File name:

a single or multiple file names to be saved.

Any occurrence of # will be replaced with the current frame number during saving. ` For example, if the current frame is 1, "Weights###.jpg"` will be replaced with ``"Weights001.jpg"

Tip

If you need to compute multiple weights per frame simultaneously use Nodes >> Compute all from main menu.
