| Abstract: |
The GPUs in modern computers, even laptops, are now sufficiently powerful that it becomes
feasible to take advantage of this power to display astronomical data interactively in new and
possibly more informative ways. AAOGlimpse is a simple experimental display program that uses
OpenGL to display FITS images (and even JPEG files) as
3D surfaces that can be rotated and viewed from different angles, all in real-time. It is
WCS-compliant and designed to handle three-dimensional data. Each plane in a data cube is surfaced
in the same way, and the program allows the user to travel through a cube by ‘peeling off’
successive planes, or to look into a cube by suppressing the display of data below a given cutoff
value. It can blink images and can superimpose images and contour maps from different sources using
their world coordinate data. A limited socket interface allows communication with other programs. |
