9. Requirements Analysis
The requirements analysis details how the system needs to be built and what functionality it will need to be complete

10. Operating Environment
Will run on any OS
Developed in Microsoft Visual Studio 6 and .NET (7.1)

11. System Components User Interface - Buttons, Tabs, Input Boxes, etc
Routines for manipulating heightmaps
- Brush, Elevation, Smoothing, Color, etc.
Routines for placing and manipulating 3D objects in the world
-Creation, Scaling, Translating, etc.

12. Software and Libraries
FLTK (Fast Light Toolkit) libraries
OpenGL libraries
FLUID was used for GUI code generation

13. Performance Requirements
The time to read/write files should be minimized
Loading/unloading portions of the world should be done in reasonable time
Rendering should be done at a rate pleasing to the eye (>30 frames per second)

14. Evaluation Metrics Creation Time - Usability
Processing Time – Frames per second

15. Software Design Multiple Classes GUI GLWindow World Sector Brush
Object

16. User Interface GUI class GLWindow class
Automatically generated with FLUID
GLWindow class
Organizes and provides access to data and rendering methods contained in other classes

17. The World World class Sector class Contains a grid of Sectors
Only stores in RAM those Sectors that have been modified
Sector class
Contains a grid of vertices (currently 32 x 32)
Each vertex contains elevation and color

18. Brushes Brush class Uses a Sector internally to represent influence
Falloff modes: none, linear, parabolic
Shapes: circle, square
Variable radius

19. Objects
Object class
Stores objects that reside separately from the terrain data
Contains orientation in 3D space and an ID
Will be rendered as loaded 3D models in the game itself

20. Difficulties
OGRE was difficult to use with deformable heightmaps.

21. Future Work
Model loading
Texturing
Better file format

25. The End
