Project Overview

7Brandon Shelton

Science on a Sphere• Developed by NOAA

• Installations across the globe (and Fiske!)

• Designed for playback of high-resolution animations• Weather patterns, surfaces of planets, historic climate, etc.

Using the SoS exhibit at Fiske, provide an interactive tool for exploring spherical geometry and simple programming

Laser Mission

The Solution: Laser Mission

Students use Laser Mission as a tool to facilitate exploration of spherical geometry and simple

programming.

•Laser Mission applies Turtle Geometry to a spherical surface.•Users Interact with the Sphere via an intuitive GUI.

Environmental Requirements

13

Project Overview

Software Environment:• Geometry on a Sphere

• Python implementation

• Sphere Emulator• OpenGL

Hardware Environment:• SOS Server

• Server at Fiske running Red Hat Linux

• Tablet PC• User Interface

Laser Mission

Functional Requirements

14

Project Overview

• Provide both a GUI and command-line interface• Command-line: simple functionality but robust for

adept programmers• GUI: complex enough to grab students’ attention, but

not too confusing that they get lost• Ensure that Laser Mission can be easily extended by

other programmers, i.e. straightforward design

Laser Mission

Issues and Ideas

Architecture

GUI Issues:• Sensitivity of Move/Turn Dials• Confusion Concerning the “Go” Button• Visualization of the Sphere in the GUI

Command-line Interpreter Issues:• Fragility of Long Programs• Command-line Parameters for Extensibility
