- (The following is avaiable from swedishchef.lerc.nasa.gov in the US, or
- at the ftp site ftp.epcc.ed.ac.uk in edinburgh overseas)
-
- "Axis" will annotate a geometric, rendered image that was constructed
- from an Explorer 3D Uniform Lattice. The user has control over the
- axes that are displayed, as well as textual information such
- as axis labels, tic labels and an image title. This module is meant
- to be used in conjunction with the "Render" module, since all of its
- output is in the geometric data set.
-
- "Axis" was written so that the user can "know where he/she is looking"
- in a render window. Although explorer is an excellent visualization
- tool, the lack of any common reference can be quite confusing after
- you've stretched, rotated and zoomed behind your image a multitude of
- times. "Axis" provides you with a common reference point, and allows
- for a bit of useful annotations.
-
- Although images rendered in conjunction with "Axis" can be used
- for presentations or reports, the extreme two-dimensionality of the
- fonts in a three-dimensional world can look a bit...strange. In a
- future release, we will offer better control of font placement,
- font type, and (hopefully) three-dimensional block fonts. Until that
- time, feel free to use "Axis" as a starting point and perhaps fill
- in the "nicities" of image label using "Showcase" or a similar
- presentation tool.
-
-
- Axis can be assembled and installed in the usual manner with
- the module builder. There is, however, one item that is a little
- different. The fonts in Axis are loaded at run time from a file
- that has the font information stored in a homegrown format.
- This font information is distributed freely with the Axis
- module in file
- Axis.pp_font01
-
- Axis looks for this file in the directory
- /usr/local/explorer/modules
-
- If you wish this file stored in a different location, or if we
- distribute more fonts in future releases, the default location
- can be overridden with the environmental variable
- EXP_AXIS_FONT
-
- Set this variable to the complete path/file name that the fonts
- are kept in.
-
-
- Axis was intended as the first step of an annotation system for
- Explorer. (Later pieces will include a better titling mechanism,
- a legend for color indexes, individual labeling of items, etc.)
- With the release of Explorer 2.0, SGI plans on including an
- annontation feature for the Explorer package. I do not know when
- they plan on releasing 2.0, but I'd rather not reinvent the wheel
- if I do not have to. If people would like to see additional
- modules to perform annontation, or if you like the way Axis works,
- I'd appreciate hearing from you. Please e-mail to the below address.
