ANN_TO_FIG
ANN Search Tree Visualization
ANN_TO_FIG
is a C++ program which
displays an image of
the search tree used by the ANN program.
ANN_TO_FIG expects as input a dump file created by the
ANN_TEST program. It creates a file in the FIG
format, which can be displayed by the XFIG program,
or converted to other formats using the FIG2DEV program.
Usage:
ann_to_fig -upiscale -xxoffset -yyoffset
-szsize -dxdimx -dxdimy -sldim AND value
-pspointsize file
reads the ANN_TEST dump file file.dmp and creates
the FIG format file file.fig.
-
-upi scale
-
specifies the number of FIG units per inch (default is 1200);
-
-x xoffset
-
sets the x offset of the bounding box (default 1 inch).
-
-y yoffset
-
sets the y offset of the bounding box (default 1 inch).
-
-sz size
-
specifies the length of the longer side of the box
(default 5 inches).
-
-dx dimx
-
the first plane dimension (default is "0", meaning the
first coordinate);
-
-dy dimy
-
the second plane dimension (default is "1", meaning the
second coordinate);
-
-sl dim AND value
-
specifies a slicing pair as a dimension and a slicing value.
-
-ps pointsize
-
specifies the radius of circles used for drawing points
(default is 10 FIG units).
Languages:
ANN_TO_FIG is available in
a C++ version.
