Member Function Documentation

depop_particules()

uint16_t lampda::modes::ParticleSystem::depop_particules ( const std::function< bool(const Particle &)> &  shouldDepopFunction )

inline

Filter particles depending on condition.

Parameters

[in]

shouldDepopFunction

A function, that given a particle, will return true if it needs to be removed from the simulation.

Returns

The number of particles left in the simulation.

init_deferred_particules()

void lampda::modes::ParticleSystem::init_deferred_particules ( uint8_t  maxParticlesToPop, const std::function< int16_t(size_t)> &  positionGeneratorFunction  )

inline

Init the particles from a initialization function, in a timed defered way.

Parameters

[in]	maxParticlesToPop	Maximum particles to spawn at this call
[in]	positionGeneratorFunction	Function that takes an index and return a led strip index

init_particules()

void lampda::modes::ParticleSystem::init_particules ( const std::function< int16_t(size_t)> &  positionGeneratorFunction )

inline

Init the particles from a initialization function.

Parameters

[in]

positionGeneratorFunction

Function that takes an index and return a ledstrip index

iterate_no_collisions()

void lampda::modes::ParticleSystem::iterate_no_collisions ( const utils::vec3d &  accelerationCartesian, const float  deltaTime_s, const bool  shouldContrain = true  )

inline

Advance the particle simulation, ignoring collisions.

Parameters

[in]	accelerationCartesian	3d acceleration vector to apply to particles
[in]	deltaTime_s	Time since last update, in seconds
[in]	shouldContrain	If true, will constrain the particles to the lamp body.

iterate_with_collisions()

void lampda::modes::ParticleSystem::iterate_with_collisions ( const utils::vec3d &  accelerationCartesian, const float  deltaTime_s, const bool  shouldContrain = true  )

inline
