There are several FLOW simulations here.
You can create the same images following the instructions.
To make it easier, we prepare a tar ball (*.tar.gz) in each example including the config-file
and a shell script 'prepare.sh'.
The 'prepare.sh' is going to download a set of SPICE kernels which size is as follows, and convert them appropriately.
Before running the scripts in this page, set the environment variables "FLOW_DATA_PREFIX" and "SPICE_TOBIN".
The following is a bash-shell example:

how to make
$ tar zxvf color_rosetta.tar.gz
$ cd color_rosetta
$ ./prepare.sh
$ flow_se color_rosetta.lua | flow_ig -o test.png
Saturn Ring (Cassini ISS NAC)

to compare.
how to make
$ tar zxvf ring_saturn.tar.gz
$ cd ring_saturn.tar.gz
$ ./prepare.sh
$ flow_se ring_saturn.lua | flow_ig -o test.png
Polygon model (Hayabusa AMICA)

kernels
overview
This example creates an asteroid Itokawa shot observed by Hayabusa at 2005-10-10T07:35:40
which corresponds to product 'ST_2447883873_b' in
Hayabusa Project Science Data Archive.
Rotate the simulated image 90 degrees clockwise to compare.
how to make
$ tar zxvf stl_hayabusa.tar.gz
$ cd stl_hayabusa
$ ./prepare.sh
$ gzip -d models/itokawa_f0049152.stl.gz
$ flow_se stl_hayabusa.lua | flow_ig -o test.png
Polygonal FOV (VEX VMC)
download
tar-ball
/
config
/
kernels
overview
Some instruments have polygonal shapes of their FOVs.
This example shows a simulation of Venus Express VMC which has the octagonal FOV.
how to make
$ tar zxvf fov_polygon_vex.tar.gz
$ cd fov_polygon_vex
$ ./prepare.sh
Download venus texture from the internet
(
search)
, then put it into texture/ directory:
$ mv (downloaded_venus.jpg) texture/venus.jpg
$ flow_se fov_polygon_vex.lua | flow_ig -o test.png
Pushbroom (SELENE TC)
download
tar-ball
/
config
/
kernels
overview
This example simulates a push broom scanner.
SELENE Terrain Camera (TC) adopted the push broom scanner,
and the SPICE IK contains only one line definition of FOV (4096 x 1).
how to make
$ tar zxvf pb_selene_tc.tar.gz
$ cd pb_selene_tc
$ ./prepare.sh
$ flow_se pb_selene_tc.lua | flow_ig -o test.png
notice
- High resolution texture is required if the observed area is narrow.
- It takes too much time because the simulation is performed repeatedly.
Dynamic Frame (Hinode SOT)
download
tar-ball
/
config
overview
This example simulates Venus Transit observed by HINODE SOT at 2012-06-05T22:30:00.
Refer to
Hinode Views 2012 Venus Transit to compare.
how to make
$ tar zxvf df_hinode_sot.tar.gz
$ cd df_hinode_sot
$ ./prepare.sh
Download
sun texture and
venus texture from the internet, then put them into texture/ directory respectively:
$ mv (downloaded_sun.jpg) texture/sun.jpg
$ mv (downloaded_venus.jpg) texture/venus.jpg
$ flow_se df_hinode_sot.lua | flow_ig -o test.png
notice
There is no HINODE's SPICE kernels, then dummy SPICE kernels are prepared:
- orbit.bsp ... dummy orbit (at 600 km above from the Earth)
- hinode.tf ... dummy attitude (Venus-oriented using Dynamic-Frame)
- hinode.ti ... dummy instrument (based on Hinode SOT)
WMS (SELENE HDTV)

config
/
kernels
overview
This example shows the simulation using Web Map Server to overlay the lunar texture.
The target is a shot taken by SELENE HDTV WIDE at 2007-11-07T05:56:00.
Refer to
KAGUYA (SELENE) Image Taking of Earth-Rise by HDTV
.
how to make
$ tar zxvf wms_selene_hdtv.tar.gz
$ cd wms_selene_hdtv
$ ./prepare.sh
$ flow_se wms_selene_hdtv.lua | flow_ig -x ge_disable_light -o test.png
notice
This example is trying to connect the USGS Web Map Server (http://onmoon.jpl.nasa.gov/wms.cgi).
DSK Type 2 (MEX HRSC SRC)

/
kernels
overview
This example shows the simulation of Phobos image taken by
Mars Express HRSC SRC at 2006-01-20T23:07:49.
SPICE DSK Type 2 is used as a shape model of Phobos.
Refer to
Sub-Mars to trailing side of Phobos
.
Rotate the simulated image 90 degrees anticlockwise to compare.
how to make
$ tar zxvf dsk_mex_hrsc.tar.gz
$ cd dsk_mex_hrsc
$ ./prepare.sh
$ flow_se dsk_mex_hrsc.lua | flow_ig -o test.png
notice
SPICE DSK Type 2 (a shape model format) is experimental.
To run this example, use alpha_dsk_c instead of the normal cspice when compiling.
Go to
alpha_dsk page in the NAIF,
and read DSK_alpha_test.pdf.
