Libraries Used:

OpenGL (obviously) - http://www.opengl.org/ SFML 1.6 (Simple-Fast Multimedia Library) - http://www.sfml-dev.org/ GLM 0.9.3 (OpenGL mathematics) - http://glm.g-truc.net/ GLM (Wavefront .obj model loader) - http://www.eden.net.nz/7/20031008glm.html GLee - http://www.opengl.org/sdk/libs/GLee/

All lib and header files are included in this repository, no extra setup should be required.

Keys

1 - 7 : toggle various render states M/N : toggle between cameras Right Ctrl : disable mouse look

Features implemented

• Terrain

  • load height values from image
  • procedurally generate height values (diamond-square)
  • multi-textured
  • lit
  • several toggleable features
    • wireframe/fill
    • light
    • texturing
    • multi-texturing
    • visualization of normals

• Fluid surface simulation

  • can interact with particle system
  • lit and blended (with lighting/blending toggleable)
  • environment mapped using skybox texture (tried to blend between day/night same as skybox, but didn't get good results)

• Particle systems

  • billboarded, textured, and blended
  • very extensible, easy to create new effects
    • ParticleEmitters contain Particles and ParticleAffectors
      • the emitter defines how to create new particles
      • the affector defines how to update particles
      • affectors are applied independently to allow for combinations of behaviors
    • ParticleSystems contain one or more ParticleEmitters
    • the ParticleManager handles the lifetime of entire ParticleSystems

• Skybox that blends between two different textures based on "time of day"

• Generic Mesh class

• Generic MeshOverlay class

  • construct by passing in another mesh and it 'drapes' itself over the parent mesh (see road)

• .obj Model loading

  • via wavefront .obj GLM library

• Generic Scene class

• Generic SceneObject class

  • extended to represent:
    • Buildings
    • Fish
    • Fishing rod
    • Fountain
    • Blimp
    • Campfire
    • Model (.obj)
    • Windmill

• Generic Camera class

  • Scene supports multiple independent cameras
    • only two at the moment, use controlled, and a follower

• Generic Light class

  • able to be repositioned and have its attributes changed
    • had a few issues with lighting though, so they don't do much at the moment

Behaviors

• Fluid surface simulation reacts to fountain particle system
• Fish swim around, staying in the main 'lake' area
• 'Runner' particle system performs a 'drunken walk' around terrain (pretend it is a very fast little mole digging around underground)
• Particle systems each have their own behavior
• Windmill spins
• Fishing pole is articulated at one joint
• circling blimp
