Laser Mission The Solution: Laser Mission Turtle Geometry Model “Turtle moving on a surface”“Turtle moving on a surface” Controlled by simple commandsControlled by simple commands i.e “Forward 10”i.e “Forward 10” “Left 90” “Left 90” “Forward 10” “Forward 10” 9 Project Overview 9 Brandon Shelton

Laser Mission The Solution: Laser Mission Science on a Sphere Science on a Sphere – Displays JPEG sequences Giant spherical globe Giant spherical globe – Written by NOAA Geometry on a Sphere – Mike Macfarrin 10 Project Overview 10 Brandon Shelton

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 surfaceLaser Mission applies Turtle Geometry to a spherical surface Users Interact with the Sphere via an intuitive GUIUsers Interact with the Sphere via an intuitive GUI 11 Project Overview 11 Brandon Shelton

Laser Mission Environmental Requirements 12 Project Overview Software Environment: “Geometry on a Sphere” Implemented in Python Written by Mike MacFarrin 2D-to-3D image conversion Sphere Emulator OpenGL and C Hardware Environment: SOS Server Server at Fiske running Red Hat Linux Tablet PC User Interface 12 Brandon Shelton

Laser Mission Functional Requirements 13 Project Overview  Interactivity!  Intuitive, easy to learn programming language  Draw many types of geometric designs on the sphere  Target users: 6 th -12 th grade students  Introduce and reinforce spherical geometry principles  User Interface  Language: Easy to learn syntax, simple functionality  GUI: Graphical representations of programming concepts 13 Brandon Shelton
