Goals

• Procedural Generation Techniques
• Referential transparency
• 3D equations
• Local randomization/realism
• Game skill adjustment
• Procedural Applications
• Terrain/Textures
• Procedural Modeling (enemies, obstacles, etc)?
• Terrain Rendering
• Local Detail/Distant Approximation
• Smart Rendering?

3
Scope

• Context Camel Crusaders
• Lion killing game (Bombs)?
• OpenGL generated
• Limits
• 3-D
• Low resolution

4
Background

• Common techniques for procedurally generated
  terrain and textures
• Spore procedural modeling and animation

5
Procedural Terrain

• Local Realism
• Random 3D midpoint displacement
• Global Referential Transparency
• Algebraic Algorithms
• Patterns of 3 Variable Functions
• Nested Trigonometric Functions
• Recursing

7
Procedural Modeling

• Temporary Models from Blender
• Enemies
• Built of ellipses
• X, y, z radii determine statistics
• X, y, and z are a function of t

8
Procedural Environments

• Dirt
• Snow
• Grass
• Forest- Tree Generation

9
Terrain Rendering

• Nearer- More Detail, Farther- Less Detail
• Rendering Only in front
• Smart Rendering?
• Problems
• Relatively Motionless-Fixed with Textures
• Flat Approximation of Dramatic Landscapes

10
What's Done

• Game Aspects
• 3D Environment, Motion Physics, Texturing
• Water (limited physics)?
• Enemies, Bombs (Drop, throw, and detonate keys)?
• Project Aspects
• 2 Java Assisting Programs (Height map and OpenGL
  modeling)?
• Fractal terrain shell and Algebraic terrain shell
• NearerGreater Detail Rendering
• In Game Map, Water

11
What's Next?

• PG Aspects
• Work to Improve Terrain Function (Iteration)?
• Create Terrain Environments
• Basic enemy generation shell
• Rendering Aspects
• Develop some kind of smart rendering?
• Increase Fps
