ParaQ:Design

Overview

This page serves as the formal gathering place for discussions, documentation, and doodling related to ParaQ design. It's the final resting place for documents that may appear other places in the site (for example, on the page for a meeting, if the document was presented at that meeting).

Initial Design

• Design document, presented and discussed at the first ParQ summit.
• Crash Test Dummies - the modern-day equivalent of straw men.

Applications

• ParaQ Applications - prototypes of specialized applications built on the ParaQ framework.

PGraph

• Plotting Parallel Data (PGraph) - Initial design for the parallel plotting framework.
• PGraph Implementation - Notes on the (current) state of the PGraph implementation.
• PGraph User Interface - Initial discussion on how users could create and interact with PGraph.

Time Support

• Time Support

Compound Filters

• Secure Connections - discusses using SSL to secure forward and reverse connections, plus reconnects, etc.
• Server Connections - discusses requirements and design for making server connections.
• Where's The State? - covers some recently-identified issues with where we store state - client or server?

Selection

• Selection - possible approaches to handling interactive selection of geometry.

Testing

• Early Testing Prototype - brief overview of the prototype testing implemented in the original "Hello, World" client.
• Testing Design - discusses the later, agreed-upon design for testing in the ParaQ client.
• ParaView 2.4.x User Testing - User testing on the existing ParaView user interface, to find out requirements and other improvments that we can make in ParaQ.
• ParaQ User Testing - User testing on ParaQ.

UI Design

• UI Design Guidelines document
• UI Design Literature Study
• High Level Usability Goals
• Popup/Panel/Modal and Non-modal Dialog Discussion

Undo

• Screen Updates - a framework for handling screen updates that allows for a wide variety of update policies.

• Screen Update / Undo Interaction - discusses use-cases where screen updates and undo / redo operations intersect.

High level design

• High Level Design - A high level design for how the core ParaQ functionality interacts with componentes of ParaQ. And how multiple applications can work with ParaQ.
