angularVelocity

angularVelocity

float G3D::ParticleSystem::Particle::angularVelocity

Used for simulation in some animation modes.

Not mapped to the GPU.

coverage

float G3D::ParticleSystem::Particle::coverage

Scales the material's own coverage.

Useful for fading out particles.

dragCoefficient

float G3D::ParticleSystem::Particle::dragCoefficient

Zero means no friction/air resistance, higher values represent increased drag.

Used for simulation in some animation modes. Not mapped to the GPU.

Used for simulation in some animation modes.

Not mapped to the GPU.

Referenced by density().

material

shared_ptr<ParticleMaterial> G3D::ParticleSystem::Particle::material

Mapped to the GPU as a texture layer index.

normal

NormalDataType G3D::ParticleSystem::Particle::normal

Scaled and biased normal, where the 4th element is the signficiance: 0 = ignore.

position

Point3 G3D::ParticleSystem::Particle::position

Relative to the ParticleSystem's frame.

This is either in object or world space depending on the value of the ParticleSystem::particlesAreInWorldSpace flag.

May not be NaN or inf.

radius

float G3D::ParticleSystem::Particle::radius

In world-space units.

Referenced by density().

spawnTime

SimTime G3D::ParticleSystem::Particle::spawnTime

userdataFloat

float G3D::ParticleSystem::Particle::userdataFloat

Arbitrary data visible in the shader as an additional attribute.

userdataInt

uint16 G3D::ParticleSystem::Particle::userdataInt

Arbitrary data visible in the shader as additional attributes.

velocity

Vector3 G3D::ParticleSystem::Particle::velocity

Used for simulation in some animation modes.
