Data Structures

• Vector.h

  • struct Vec2
  • struct Vec3

• Point.h

  • struct Vertex
    • A simple type of points with only position and normal data
    • Used in rigid body (without texture or anything else)
  • struct Particle
    • Point with physical properties.
    • Fluid consists of particles.
    • Execute boundary and collision detection actively.

• Rigid.h

  • struct Ground
  • struct Sphere
  • struct Ball
    • Ball struct include a center data and a sphere.

• Fluid.h

  • struct Boundary
    • The container of fluid.
  • class Fluid
    • Applied SPH algorithm.

• Program.h -> Shader program built itself from .glsl files

  • class Program
    • Compile and connect shaders then make rendering program.

• Display.h -> Global camera, light & Renderers for cloth and rigid bodies

  All those render classes accept only the pointer of the thing it renders. Call their flush() function in the main render loop.

  • struct Camera
  • struct Light
  • class BoundaryRender
  • class FluidRender
  • class RigidRender
  • class GroundRender
  • class BallRender
