 SCIRun has nine geometric meshes available for Fields:
 
-- **PointCloudMesh**: unconnected points
-- **ScanlineMesh**: regularly segmented straight line (a regular 1D grid)
-- **CurveMesh:** segmented curve
-- **ImageMesh**: regular 2D grid (see note below)
-- **Structured Quad Surface mesh**: surface made of connected quadrilaterals on a structured grid
-- **Structured Hex Volume mesh**: subdivision of space into structured hexagonal elements
-- **TriSurfMesh**: surface made of connected triangles
-- **QuadSurfMesh**: surface made of connected quadrilaterals
-- **LatVolMesh**: regular 3D grid
-- **TetVolMesh**: subdivision of space into tetrahedral elements
-- **HexVolMesh**: subdivision of space into hexagonal elements
-- **PrismVolMesh**: five faces, two triangular faces connected together by three quadrilateral faces.
