Current revision
The following series of How Tos show you how to solve a range of common visualisation problems with S2PLOT. They are not intended to provide a complete user guide to all the functionality of S2PLOT, and should be supplemented by looking at the Function List.
Choose from either C, Fortran or Python categories depending on your preferred programming mode. The How Tos assume that you have a working, a tested, version of S2PLOT installed on your system, and that you have suitable compilers available.
Spherical coordinate systems in S2PLOT in C
Astronomers like to use spherical coordinate systems, but S2PLOT would prefer you to use Cartesian coordinates. To aid in the development of visualisations that require spherical coordinate grids, we have put together some sample code.
Please download us2spherical.c, us2spherical.h and spheredemo.c and follow the instructions in the comments spheredemo.c.
How To ... in C
- Getting started
- Drawing points
- create, modify and travel along a camera flight path
- draw and save specific views of a model / visualisation
- wrap a large-area FITS file on to the celestial sky
- Make textures transparent
- Use an OpenGL callback function
- Follow an object with the camera
- use panels
- S2PLOT coordinate systems: world coordinates, screen coordinates
How To ... without (much) programming
- Run an existing S2PLOT program over a background image
- "Script" key presses for S2PLOT
- Create an s2slides presentation
- Convert images to textures
- Create and embed 3-d figures in PDF files
- Create and embed 3-d figures in web pages (using Flash)
