Dragonfly supports the creation, importation, and visualization of meshes, which are collection of vertices, edges, and faces that can define 3D surface geometries in computer graphics and solid modeling. It is possible to examine mesh properties and scalar values, select a fill mode, choose colors, smooth meshes, and to export meshes to a number of common file formats.
The following options for creating meshes are available in Dragonfly:
Contour meshes… You can generate contour meshes that describe the contour around values in a dataset that are above the selected lower threshold (see Generating Contour Meshes). Contour meshes can also be generated from regions of interest (see Generating Contour Meshes from ROIs).
Regions of interest… Regions of interest can be exported as meshes either normally, with sampling, or confined within a cubic structure (see Exporting ROIs to Meshes). Thickness meshes, which show the referential values of local thickness between boundary points, can also be computed from regions of interest (see Exporting ROIs to Thickness Meshes).
Active contour… Dragonfly's Active Contour feature lets you quickly and efficiently complete segmentation tasks. The Active Contour workflow begins with adding a series of paths to the 2D views of volumetric image data, fitting the closed splines (known as snakes) to object boundaries, and then generating a mesh that fully describes the surface of the targeted feature of interest (see Active Contours).
Multi-ROIs… Meshes can be created from multi-ROIs, in which the scalar values of the multi-ROI are retained (see Multi-ROI Pop-Up Menu).
