BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
SIDB (Scientific Image Database) is a Web-driven database for (scientific) images. Entry of image meta-data is facilitated through the use of user-definable templates. Users have complete control over who else may see the submitted image and data. SIDB offers various views on the actual image data. Thumbnail plus meta-data can be printed, and multiple thumbnails can be combined in galleries. A freeware version of the Huygens software (http://www.svi.nl) can be used to generate projections from 3-D images (most confocal microscope image formats are supported), as well as MPEG movies, showing the individual layers from the 3-D images.
PHPLOT is a PHP graphics class for creating charts and plots. It works with PHP5 (but older versions can use PHP4). PHPlot uses the PHP GD extension to produce PNG, GIF, or JPEG images. TrueType fonts (TTF) are optional, or built-in GD fonts can be used. The available plot types are: area, bars, line/points, lines, pie, points, squared, stacked-bars, and thin bar-line. Labels, tick marks, plot legend, X/Y axes, and more are all configurable. Images can be imported as a background, multiple graphs can be drawn on one image, and images can be saved to disk or returned to a browser.
PasTmon (Passive Application Response Time Monitor) passively monitors your application servers, measuring and reporting user response times, throughput and congestion. It currently works with HTTP, telnet, rlogin, rsh, FTP (control channel), SMTP, POP3, and IRC. Measurements are recorded in a PostgreSQL database and are presented graphically via a PHP Web front-end using R statistical analysis scripts to create the plots.
DTGraph builds graphs and stats based on temperature readings stored in MySQL from any temperature measurement interface such as 1-wire/digitemp (even Web sources if desired). It can show closeups of particular intervals and sensors. Several useful utilities for alarm notifications and mobile monitoring are also included.
The PHP SETI@home web monitor is a very simple PHP script to monitor a single SETI@Home program running on a workstation or server via the local Web server. It displays general information of the user, the current work unit and the processing statistics. It also displays a skymap to show the source of the current data.
