Object Distance

icon

Calculate distance from the surface of other meshes.

object_distance

Specify up to 6 objects or a collection to measure distance from.

Signed/Unsigned Distance

  • Unsigned distance is the absolute distance to nearest surface.
  • Signed distance will produce negative distances on the inside of objects.

  • Unsigned Distance

    unsigned_dist

  • Signed Distance

    signed_dist

Signed distance will allow isloation of outside/inside areas when remapping.

Union Islands

There is an option to union Boolean manifold islands before calulating distance. This removes artifacts caused by overlapping surfaces.

Outputs

  • Output: Distance point attribute.
  • Color: Distance attribute as color (used for visualisation).

Settings

Objects

  • Objects/Collection: Choose up to 6 objects or a collection:
    • Objects.
    • Collection.
  • Object Count: Number of objects to include.
  • Union Manifold Islands: Union manifold mesh islands. This removes areas of mesh overlap.

Distance

  • Distance: How to measure distance from surface.
    • Unsigned: Absolute distance from the surface.
    • Signed: Areas inside the surface have negative distance, outside areas have positive distance.
  • Min Distance: Points closer than this will be black.
  • Max Distance: Points further away than this will be white.
  • Interpolation: Interpolation of distance to value.
    • Linear.
    • Smooth Step.
    • Smoother Step.
  • Invert: Invert the values of the distance attribute.

Blur

Blur the distance attribute.

  • Iterations: How many times to blur the values for all elements.
