This project contains a definition of a module which creates `wiggle' displays in seismic (or other) data. It requires a 2D structured mesh as input. It computes coordinates and connectivity lists for a polyline and polytriangle strip. These are the input to the polyline_mesh and polytri_mesh field mappers. Data can be added to the output fields through the use of the interp_data module.
direction
Boolean parameter which specifies whether the direction of the wiggle is along the x axis (0) or along the y axis (1). This parameter is controlled by the `Wiggle Direction' radio box options.
scale
Floating point parameter that specifies by how much the seismic data should be scaled. This parameter can be modified by the use of the `Wiggle Scale' slider.
mode
Integer list parameter which allows you to choose the type of area fill: 0: no fill, 1: fill above base line, 2: fill below base line, 3: fill above and below base line. This parameter can be modified by the use of the `Wiggle Mode' option menu.
component
Boolean parameter which allows you to specify which data component to use. This parameter can be modified by the use of the `Wiggle Component' radio box.
offset
Floating point parameter which can be used to move the base line of the wiggle. This parameter can be modified by the use of the `Wiggle Offset' field.
out_line
Mesh data output that contains the geometry data read from the field file. The output consists of the nodal coordinates and a single triangle cell-set that describes the connectivity of the data. No node data or cell data is output.
out_mesh
Mesh data output that contains the geometry data read from the field file. The output consists of the nodal coordinates and a single triangle cell-set that describes the connectivity of the data. No node data or cell data is output.
out_obj
The directly renderable output of the wiggle macro. This output contains the geometry data read from the field, in a form that can be rendered by the standard data viewers.
The WiggleFunc functional macro uses the WiggleCore low-level module. The wiggle user macro uses this functional macro and the WiggleUI user interface macro. All of these macros use the WiggleParams parameter block to communicate parameters between themselves.
One example application is provided with the Wiggle project. The WiggleEg example application uses read_field to read one of the AVS datasets. The dataset is preprocessed using the orthoslice and downsize modules before it is passed into the wiggle module.
iac_proj/wiggle/wigmods.v contains the V definitions of the WiggleCore module and the WiggleParams parameter block.
iac_proj/wiggle/wigmacs.v contains the V definitions of the WiggleUI UI macro, the WiggleFunc functional macro and the wiggle user macro.
iac_proj/wiggle/wigapps.v contains the V definitions of the WiggleEg example application.
