These modules create geometric structures for rendering and display (e.g., bands, triangle connections, isosurfaces, and boundary boxes). In some ways, these modules are the heart of DX in the sense that they convert data into viewable geometry. However a few other modules in the annotation catagory (glyph, autoglyph, ribbon, tube, plot) convert data to geometry also.

• Band -- Divides a Field into bands based on given division values.

• Connect -- Creates triangle connections for a Field of scattered positions.

• Construct -- Constructs an arbitrary Field. You can specify the origin, the deltas, the counts in each dimension, and the data. You can also use Construct to create a Field containing a "positions" component with given position values (e.g., the output of the ProbeList tool).

• Enumerate -- Generates a numeric list.

• Grid -- Produces a set of points on a grid. You can construct rectangles, ellipses, lines, crosshairs, and bricks. You can specify the size of the object and the number of points in the grid.

• Isolate -- Shrinks the connections elements of a Field so that they can be individually seen.

• Isosurface -- Creates surfaces or lines of constant value. For volumetric inputs, it creates isosurfaces; for surface inputs, contour lines. Use the ClipPlane module to display the interior of an isosurface.

• MapToPlane -- Maps a 3-dimensional data Field onto an arbitrary plane. You can specify a point and a normal to define the plane.

• Regrid -- Maps a set of scattered points onto a specified grid.

• RubberSheet -- Deforms a surface field (composed of triangles, quads, or lines) by an amount proportional to the data value at each point. You can use the Normals or FaceNormals module to add shading before rendering.

• Sample -- Produces a set of points in an arbitrary field. For example, you can produce a set of approximately evenly spaced samples on an isosurface.

• ShowBoundary -- Creates a renderable object that is the boundary of a volumetric field.

• ShowBox -- Creates a set of renderable lines that represent the bounding box of a field.

• ShowConnections -- Creates a set of renderable lines that represent the connections of elements in a field.

• ShowPositions -- Creates a set of renderable points that represent the positions of a field.

• Streakline -- Computes a line that traces the path of a particle through a changing vector field. The data input to the module is a vector field series, or a single field that is a member of a vector field series. You can control the starting points of the streaklines, and can optionally provide a curl field to produce twist on any ribbons or tubes constructed from the streakline.

• Streamline -- Computes a line that traces the path of a particle through a constant vector field. The data input to the module is a vector field. You can control the starting points of the streamlines, and can optionally provide a curl field to produce twist on any ribbons or tubes constructed from the streamline.
