68 Chapter 1 An Overview of the Shake User Interface

Right-click the Viewer DOD button to access the DOD control options. For example,

using Frame DOD to Viewer (sets the DOD to the Viewer frame), you can zoom in on an

area you want to focus on and limit your DOD to that area. Note that the DOD is not

dynamic, as it would need to constantly recalculate as you pan. For more information,

see “T

he Domain of Definition (DOD)” on page 82.

Creating Your Own VLUTs and Viewer Scripts

The preset examples are stored in the end of the nreal.h file. To roll your own, you first

declare them in a startup directory following the same guidelines as for macros. The

following functions do absolutely nothing:

image ViewerLookup1_(image img)

{

return img;

}

image ViewerScript1_(image img)

{

return img;

}

Next, also in a startup file, hook them into the Viewers:

nfxDefViewerLookup(“Lookup1”, “ViewerLookup1_()”, “default”);

nfxDefViewerScript(“Script1”, “ViewerScript1_()”, “default”);

The first argument (“Lookup1”, “Script1”) is the name of the VLUT/Script as it appears in

the list in the interface. The second arguments (“ViewerLookup1_()”, “ViewerScript1_()”)

are the actual functions they call when activated. These must be declared in a startup .h

file. The third arguments are the optional icon files, relative to the icons/viewer

directory. It is assumed there is an .nri extension and that you also have a focused

version called [icon].focus.nri.

Therefore, if you want to load a button called icons/viewer/vluts/dufus.nri, you also

create a focused version called icons/viewer/vluts/dufus.focus.nri. You then use “vluts/

myVLUT” as your icon name. “default” means it is looking for [email protected], [email protected],

[email protected], and [email protected] (@ = 1, 2, 3, etc.). All paths are relative to icons/

viewer. The icons for Viewer scripts are 30 x 30 pixels, no alpha. The standard VLUT

buttons are 51 x 30 pixels, no alpha. See “Other Macros–VLUT Button” in Chapter 32,

“The Cookbook.” Other macros required to run the VLUT Button macro can be found in

doc/html/cook/macros.
