Public Methods

Method	Description
Draw ( NamedBoxCollection data ) : void
GrowCapacity ( int size ) : void	Increases the capacity of this system by the specified amount.
Initialise ( ParticleSystemDescription description ) : void	Initialises this ParticleSystem instance.
ParticleSystem ( GraphicsDevice device ) : System.Diagnostics	Initializes a new instance of the ParticleSystem class.
Spawn ( System.Numerics.Vector3 position, System.Numerics.Vector3 velocity, float angularVelocity, float size, float lifetimeScale, Microsoft.Xna.Framework.Color startColour, Microsoft.Xna.Framework.Color endColour ) : void	Spawns a new particle.
Update ( float dt ) : void

Private Methods

Method	Description
AddNewParticlesToVertexBuffer ( ) : void	Helper for uploading new particles from our managed array to the GPU vertex buffer.
CalculateWorldView ( Matrix4x4 &view ) : void
FreeRetiredParticles ( ) : void	Helper for checking when retired particles have been kept around long enough that we can be sure the GPU is no longer using them. It moves old particles from the retired area of the queue to the free section.
IGeometry ( Myre.Graphics.Materials.Material material, Renderer renderer ) : void
IGeometry ( string phase, Renderer renderer ) : void
InitialiseBuffer ( ) : void
RetireActiveParticles ( ) : void	Helper for checking when active particles have reached the end of their life. It moves old particles from the active area of the queue to the retired section.
SelectParticleType ( ) : void
