Purpose

The MarkersToSurface module allows for generating a surface from a list of markers by rasterizing the markers as spheres.

The rasterization is somewhat coarse, but the resulting surface can be smoothed and modified using level set filters provided by OpenVDB.

This module can be used, for example, to perform surface reconstruction of particles represented as markers.

Apply

name: apply, type: Trigger

Overwrite label and description

name: overwriteLabelDescription, type: Bool, default: FALSE

Grid Cell Size

name: gridCellSize, type: Double, default: 1

Sets the grid size of the cells.

Markers with a radius smaller than the grid size will not be accurately represented.

Adaptivity

name: adaptivity, type: Double, default: 0.2

Sets the adaptivity of the mesh generator.

Radius Mode

name: radiusMode, type: Enum, default: FixedRadius

Defines the mode for the radius of the markers.

Values:

Title	Name	Description
​Fixed Radius	​FixedRadius	​Use the Radius field.
​Marker Radius	​MarkerRadius	​Use the length of the vec component of each marker.

Radius

name: radius, type: Double, default: 4

Sets the fixed radius.

Radius Scale

name: radiusScale, type: Double, default: 1

Sets the radius scale that is multiplied by the marker radius if per-marker radius calculation is used.
