First draft of a list of features

• Particle Grouping
  • Group Sizes
  • Rotation around centre
  • Attraction and repulsion within the group
• Alpha Blending
  • Variable blending types
• Variable emission rates
  • Emission rates that change over time
  • Emission to max particles
  • Emission to time limit
• Variable particle sizes
  • Particles sizes that change over time
  • Different particles sizes for each particle
  • Random particle sizes within a range
• Variable particle colours
  • Colour Cycle
  • Colour Change while running(on function call)
  • Colour change over time
• Emission Patches
  • Particles emitted from lines, line strips and points
  • Particles emitted randomly from within a polygon
    • Possibly point weighting
  • Transformation of patches
    • On the fly and set pre-calculated transformations
  • Morphing
    • Morphing of individual points within the patch
• Emission control
  • Emit towards a point
  • Emit away from a point
  • Emit in a direction
  • Emission flight paths
    • Possibly variable flight paths
    • Possibly Flight path cycle
    • Possibly Flight path change on the fly
    • Possibly emission flight path equation plug-ins
• Velocity inheritance
  • Adjustable Percentage of velocity inheritance
• Variable velocity and inheritance rates
• Burst emission
• Particle ribbons
• Positional adjustments
  • Set up areas around the system that change the properties of the particles when they pass through it
  • Multiple areas
  • Multiple changes per area
• Particles textures
  • Texture animations
  • Texture transformation
  • Decals
  • Support for shaders(height maps mainly)
• Particles types
  • Quads, triangles , custom etc…
• Constant systems
• Particle attributes
  • Individual attraction/repulsion
  • Inter-particle collision detection
• Pluggable or overridable control of particle movement
  • example sinusoidal motion or even AI
• Pluggable or overridable particle renderer
  • a classic renderer might render each particle as a sprite or a geometry instance, another renderer might draw lines between particles for a lightening or web effect, another renderer might distort a nice blue shaded geometry-grid based on particle positions for a water effect.
• Super emission(particles emitting particles)
