Full HTML Index
Scivis is a client-server data visualization and analysis system which takes full advantage of Java.
The purpose of this system is provide researchers with a customizable data analysis system to aid their research.
We also provide a collaborative framework, where the users can exchange data and their own personalized filters.
Available via http://kopernik.npac.syr.edu:8888/scivis
NOTE: Scivis is not Web-based. It's a visualization server (Java application).
  • ScivisLight will be a browser version of Scivis, but will not be as powerful as Scivis!

Foil 7 Visualization Sever Model-I

From Scivis Java Visualization System ISDA Meeting Doubletree Hotel Pasadena -- March 25-27. *
Full HTML Index
Scivis is a visualization server.
Simulations servers connect to Scivis with Pipes.
  • They send data to Scivis via API's that we provide.
  • These API's open up temporary connections to Scivis.
  • These servers may just read in data and pipe it to Scivis.

Contour Server
  • Originally we implemented the contour server as part of Scivis.
    • This server was slow, and a major bottleneck in Scivis.
  • Currently, we are implementing the contour server as "C" code, and Java code.
  • The Contour server calculates the contour, and sends the data to Scivis.

Foil 10 User-Definable-Filters

From Scivis Java Visualization System ISDA Meeting Doubletree Hotel Pasadena -- March 25-27. *
Full HTML Index
A filter is an action which is performed on a data set(s) to create a new data set based on this action.
We provide an infrastructure for users to create their own filters.
Filters can be created on-the-fly and can be shared among collaborators. We provide a Wizard to create filter templates.
Examples:
  • Merging of data sets by a point-and-click interface.
  • Extraction 1d data from 2d data over x and y values
  • Numerical method filters:
    • Cubic Spline.
    • Derivatives in Space and Time.

Foil 11 General Collaboration

From Scivis Java Visualization System ISDA Meeting Doubletree Hotel Pasadena -- March 25-27. *
Full HTML Index
Still developing and experimenting to find the best framework.
  • Different uses will need different approaches
There are several possible methods to implement:
  • Using Custom Socket programming
    • Fast
    • Very expensive to maintain elegant programming
  • Using Remote Method Invocation(RMI)
    • RMI is an abstraction for communicating between Java virtual machines.
    • It's not as efficient as a direct sockets-based method. (5 times slower than socket programming)
  • Existing Collaboration Tools (TANGO, etc..)
Scivis uses the socket model.
We are working with people at Rutgers to define a different collaboration model.

Foil 17 Collaboration with Filters

From Scivis Java Visualization System ISDA Meeting Doubletree Hotel Pasadena -- March 25-27. *
Full HTML Index
Since filters are user-definable, different users in a collaboration can have different filters.
If a user in a collaboration runs a filter, her/his local version of Scivis checks to see if the other collaborator(s) have this filter.
  • If they do, then we send the command of the filter.
  • If not, we use serialization to send the class file, of the filter, to Scivis.
This system will allow users to exchange new filters among the collaborators
