Constructor & Destructor Documentation

ON_Particle() [1/2]

ON_ParticleSystem::ON_Particle::ON_Particle

(

)

The default constructor does not initialize the values of the m_mass, m_position m_velocity and m_force.
It sets m_particle_id = 0 and m_context = 0;

ON_Particle() [2/2]

ON_ParticleSystem::ON_Particle::ON_Particle

(

const ON_Particle &

src

)

Remarks: The copy constructor copies the values of every field including m_context and m_particle_id.

Member Function Documentation

DistanceMoved()

double ON_ParticleSystem::ON_Particle::DistanceMoved

(

)

const

Returns: The distance from the previous position to the current position. If either the previous or current positions are unset, then ON_UNSET_VALUE is returned.

IsFixed()

bool ON_ParticleSystem::ON_Particle::IsFixed

(

)

const

operator=()

ON_Particle& ON_ParticleSystem::ON_Particle::operator=

(

const ON_Particle &

src

)

Remarks: The operator= copies the values of every field except m_particle_id, which is left unchanged.

m_context

ON__UINT_PTR ON_ParticleSystem::ON_Particle::m_context

each application can use m_context as it sees fit.

m_current_state

ON_ParticleState ON_ParticleSystem::ON_Particle::m_current_state

current mass, position, and whatever else this system cares about

m_particle_id

const unsigned int ON_ParticleSystem::ON_Particle::m_particle_id

0 != (0x80000000 & m_particle_id) indicates the particle will not be moved by ON_ParticleSystem::IncrementTime().

m_previous_state

ON_ParticleState ON_ParticleSystem::ON_Particle::m_previous_state

previous mass, position, and whatever else this system cares about
