This is an overview for the different tools that are currently planned for the curves sculpt mode. This list is based on meetings in the geometry nodes module. More stuff will probably be added over time.

Brushes:

• Comb (T96445): Same basic behavior as the old comb brush.
• Add (T96444): Used to add a fixed number of curves. Often this is used to just add a single guide curve at a time.
• Delete (T96446): Removes curves within the brush radius completely.
• Density (T96440): Used to add or remove hair to achieve a specific density that is a setting of the tool.
• Grow/Shrink (T96447): Used to grow and shrink existing curves gradually. The approximate shape of the existing curve does not change. Growing extrapolates the existing curves based on one or more heuristics.
• Snake Hook (T96448): Used to extend curves into a specific direction.
• Cut (T96450): Used for precise trimming of hair.

Some brush settings:

• 2D projection vs. 3D brush. We have to iterate on how to determine the center of a 3D brush.
• Front Faces Only
• Brushes that add new curves (Add/Density) need interpolation settings.
  • Interpolate Length
  • Interpolate Shape
  • Interpolate Attributes
