shapeViewer is a publicly available scientific software designed to display a 3D model of a
comet/asteroid, simulate observations from a space mission, project data on the shape.
It provides a series of tools specifically developed for mapping and geomorphological investigation.
shapeViewer has been used for operations planning and scientific analysis by the Rosetta (ESA)
and Dawn (NASA) missions since 2010. shapeViewer officially supports future missions to asteroids and comets
(CAESAR, Lucy, Hayabusa 2).
3D display of small bodies shape models with photometrically accurate rendering,
switch to a new mission or load shapes with > 1 million facets in less than a second, runs at 60 FPS on a standard laptop,
interactive visualization of the illumination conditions, accurate shadows,
real time rendering of operational scenarios (e.g. a fly-by), spacecraft orbit and attitude provided by SPICE, pre-configured for each mission,
retrieval of observation geometry and solar angles (incidence, emission, phase, elevation),
calculation and display of the gravity field and effective slopes on the surface,
accurate projection of images and other datasets on the shape, individually or in a user-defined sequence (on the fly, no need for any preprocessing of the data),
view and export cylindrical, orthographic maps,
measure distances and areas on the shape, or on projected images,
extract topographic profiles,
... and many other features

Visualizations can be exported as individual frames and assembled in a movie.
Here, videos are played back at the same frame rate they run in shapeViewer itself.

shapeViewer can be used to simulate images of any space mission for which SPICE kernels are available.
Several mission packages are available by default, or can be downloaded here.
To use a mission package, sinmply unzip the downloaded archive into the "missions" folder in your shapeViewer directory.
You load the new mission by selecting the relevant XML file (e.g. "Rosetta_67P.xml") from shapeViewer's menu ("File/Load mission package...").
Each package contains everything needed for the given mission (shape models, kernels) and pre-congifures the software accordingly.
Deep Impact at comet Tempel 1 (to be available soon)
Stardust/Next at comet Hartley 2 (to be available soon)
Hayabusa 2 at asteroid Ryugu (not public, in preparation for the H2 team)
Lucy at trojan Eurybates (not public, distributed to Lucy team on request)
Dedicated packages can be generated easily for other missions (i.e. OSIRIS-REX), contact me fore more information.
Download and install
shapeViewer is currently distributed for Windows systems only (see note below).
It is provided as a single zip file. Extract it in the folder of your choice, and run the shapeViewer.exe executable file.
A graphic card supporting at least OpenGL 2.0 is necessary (usually true if your computer was built after 2004).
Note: shapeViewer is built with cross-platform libraries and can be compiled for other systems.
I personally run a native shapeViewer on Ubuntu 16.04 but do not have the resources to package it and distribute reliably.
Contact me if you absolutely need a native version, and we may work out a solution.
Many users have reported using successfully the Windows executable on Mac OS and Linux systems through the WINE interface.
shapeViewer is distributed with a user manual which can be consulted offline and within the software.
The latest version is also available on this website.
Latest changelog (complete list in User Manual)
shapeViewer 3.0.2 - 27/07/2018
- support for Hayabusa 2 mission (config files not publicly available for now)
- "activecolor" command to define the color of selected lines/facets
- "paintfov" command to paint the facets currently in the FOV with the active color
- "outlinefov" command to mark the projected contour of the current FOV (EXPERIMENTAL)
- "exportfov" command to write facets currently in FOV to a data file
- "clean" command to reset the colors
- "export" command renamed to "export3d"
- "clim" command now works also when displaying angles (i, e, phase)
- corrected syntax for loading "facet" data in this help file
- wrong FOV definition in Lutetia package
