Module: ROI Box ()

Description:

This module defines a region-of-interest with the shape of an axis-aligned 3D box. This box can be used to restrict the output of many visualization modules like Volume Rendering, Image Ortho Projections, or all modules derived from View Base, e.g., Isosurface or Surface View.

When a SelectRoi is created, a 3D box with green handles is displayed in the 3D viewer that can be adjusted interactively. In the Project View, the ROI input port of the visualization modules should be connected to the SelectRoi object in order to restrict the visualization.

Connections:

Data [required]
Connection to a 3D data object which defines the maximum size of the region-of-interest. Only the bounding box of the data object but not the data itself is interpreted by this module.

Ports:

Minimum

Minimum x-, y-, and z-coordinates of the region-of-interest.

Maximum

Maximum x-, y-, and z-coordinates of the region-of-interest.

Options

If the option show dragger is enabled a tab-box dragger is shown which allows you to interactively adjust the region-of-interest in the 3D viewer.

Draw

After pressing the restrict button you can draw a contour in the viewer window in order to restrict the region-of-interest. However, note that although you can draw an arbitrary contour the region-of-interest itself still remains a box. The reset button resets the box so that is covers the full bounding box of the connected data set.

Size

Size of data in the region of interest in MBytes. This port is available only for regular grid.
