Purpose

The MarkersToSurface module allows to generate a surface from a list of markers by rasterizing the markers as spheres. The rasterization is a bit coarse, but the resulting surface can be smoothed and modified using level set filter provided by OpenVDB.

This module can be used to e.g. do a surface reconstruction of particles represented as markers.

Overwrite label and description

name: overwriteLabelDescription, type: Bool, default: FALSE

Grid Cell Size

name: gridCellSize, type: Double, default: 1

The grid size of the cells. Markers with a radius smaller than the grid size will not be well represented.

Adaptivity

name: adaptivity, type: Double, default: 0.2

The adaptivity of the mesh generator.

Radius Mode

name: radiusMode, type: Enum, default: FixedRadius

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

The radius scale is multiplied with the marker radius if per-marker radius calculation is used.
