Detailed Description

2-D particle system data.

This class is the key data structure for storing particle system data. A single particle has position, velocity, and force attributes by default. But it can also have additional custom scalar or vector attributes.

Member Function Documentation

◆ AddParticle()

void CubbyFlow::ParticleSystemData2::AddParticle	(	const Vector2D &	newPosition,
		const Vector2D &	newVelocity = `Vector2D()`,
		const Vector2D &	newForce = `Vector2D()`
	)

Adds a particle to the data structure.

This function will add a single particle to the data structure. For custom data layers, zeros will be assigned for new particles. However, this will invalidate neighbor searcher and neighbor lists. It is users responsibility to call ParticleSystemData2::BuildNeighborSearcher and ParticleSystemData2::BuildNeighborLists to refresh those data.

Parameters

[in]	newPosition	The new position.
[in]	newVelocity	The new velocity.
[in]	newForce	The new force.

◆ AddParticles()

void CubbyFlow::ParticleSystemData2::AddParticles	(	const ConstArrayAccessor1< Vector2D > &	newPositions,

		const ConstArrayAccessor1< Vector2D > &	newForces = `ConstArrayAccessor1< Vector2D >()`
	)

Adds particles to the data structure.

This function will add particles to the data structure. For custom data layers, zeros will be assigned for new particles. However, this will invalidate neighbor searcher and neighbor lists. It is users responsibility to call ParticleSystemData2::BuildNeighborSearcher and ParticleSystemData2::BuildNeighborLists to refresh those data.

Parameters

[in]	newPositions	The new positions.
[in]	newVelocities	The new velocities.
[in]	newForces	The new forces.

size_t CubbyFlow::ParticleSystemData2::AddScalarData ( double initialVal = 0.0 )

Adds a scalar data layer and returns its index.

This function adds a new scalar data layer to the system. It can be used for adding a scalar attribute, such as temperature, to the particles.

Parameters

[in] initialVal Initial value of the new scalar data.

◆ AddVectorData()

size_t CubbyFlow::ParticleSystemData2::AddVectorData ( const Vector2D & initialVal = Vector2D() )

Adds a vector data layer and returns its index.

This function adds a new vector data layer to the system. It can be used for adding a vector attribute, such as vortex, to the particles.

Parameters

[in] initialVal Initial value of the new vector data.
