Input Curves Config

Overview

Stitches Curves Config is a utility node designed to prepare custom curves for use with the Fibric Stitches node. It provides preprocessing tools for curves sourced from multiple methods including direct mesh drawing, UV drawing, and image-based curve generation from contrast differences, ensuring curves are properly optimized before being fed into the stitch engine.

The node includes a From Image method that generates stitches procedurally from texture contrast. To use this method, you must connect the mesh to the node's input so it can properly read the UV coordinates. 

General

• Type

  • On UVs:  For when users draw curves in 2D UV space by using the UV output from Fibric Stitches in template mode, allowing precise 2D stitch layouts.

  • On Mesh: For when users draw curves directly onto the 3D mesh geometry using a Draw Curve SOP node.

  • From Image: Generate curves procedurally from textures using an internal trace SOP node, but with UDIM texture support. (Mesh needed in second input)

• Name
  Attribute name of curves

• Resample
  Resamples curves into even-length segments.

• Smooth
  Relax curves without increasing the number of points.

• Reverse order
  Reverse curve point order.

• Keep Color
  Keeps curve input color.

From Image

To use this method, you must connect the mesh to the second node's input so it can properly read the UV coordinates. 

• Image File
  Path to texture or COPs setup.

• UDIM Filename Expansion
  Toggle to activate UDIM token usage.

• Channel
  Channel to be used.

• Threshold
  Adjusts the image value sensitivity for determining which regions convert into curves from image contrast.
