General Module Function
The modify_data_3D
Module Input Ports
modify_data_3D has two input ports. The left input port will accept 3D field (mesh AND nodal data) which contains the data to be altered.
The right input port accepts the z scale (exaggeration) of the incoming coordinates.
Module Output Ports
modify_data_3D has two output ports.
The left port outputs the data field with modified nodal data. This port can be connected to any module that can process data fields, such as the isolines module, which can use the data field to display isolines if the output were a surface. The right port outputs a renderable version of the modified data.
Module Control Panel
The control panel for modify_data_3D is shown in the figure above.
The Center of Modification panel has sliders (with "" buttons to access type-ins) that control the center and radius of the
Glyph Display Radius is the size (in your units) of the spherical glyph that identifies the center modification location.
Outer Change Radius: is the radius in the x-y plane of the total region affected.
Inner Change Radius: is the radius in the x-y plane of the region affected at the constant Inner Weighting.
Modification Value is the value to change (clamp) the data set.
Inner Weighting is the constant value over the inner change radius.
Transition Options
Linear causes the weighting to be a straight line (linear interpolation) from the Inner Weighting value to zero at the outer change radius.
Non-Linear is a smooth transition (no discontinuities in slope) from the Inner Weighting value to zero at the outer change radius.
Horiz./Vert. Anisotropy is the ratio of the change radius in the x-y plane to the vertical (z) direction (for undistorted..not z-scaled coordinates).
Pre-Altered Z Scaling is the z-exaggeration you are using for display purposes.
Display Points toggle controls whether the affected nodes (cloud of points) will be displayed.
(Display) Data Component is the data component that is used for coloring the cloud of points.
modified_data will show the data as modified.
original_data will show the data as it is unmodified.
distance is the from the center.
change is the amount of change to the data.
Create Modified Output Field button causes the modified data to be output.
The figure below shows the cloud of points display from this module. Note the adaptively gridded regions with clusters of nodes!
