Acceleration is not a property of a particle in a particle system. Instead, it is calculated based on the forces acting on the particle.

The inverse square force is commonly used to simulate gravity in particle systems because it accurately models the gravitational force between particles.

Volumetric rendering is a technique used to render particles as they move through a volume. It takes into account the density and opacity of the particles to create realistic effects.

Rigid body dynamics is not an application of particle systems. It is a separate field of computer graphics that deals with the simulation of rigid objects.

Particle seeding is the technique used to generate a distribution of particles within a volume. It involves placing particles at specific locations or using a random distribution algorithm.

A Verlet integrator is used in particle systems to calculate particle positions at a given time step based on their previous positions and velocities.

Phong shading is not a type of volumetric rendering technique. It is a shading technique used in computer graphics to render surfaces.

Particle sampling is the process of calculating the contribution of each particle to the final image in volumetric rendering. It involves determining the opacity and color of each particle along a ray.

Lighting is not a factor that directly affects the quality of a particle system simulation. It is a factor that affects the appearance of the particles in the final rendered image.

Particle collision is the technique used to simulate the interaction between particles in a particle system. It involves calculating the forces between particles and updating their positions and velocities accordingly.

Rigid body is not a type of particle system. It is a separate field of computer graphics that deals with the simulation of rigid objects.

A bounding volume hierarchy (BVH) is used in particle systems to accelerate particle-particle collision detection. It involves creating a hierarchy of bounding volumes that enclose the particles, allowing for efficient collision detection.

Electrostatic force is not a type of force commonly used in particle systems. It is a force that acts between charged particles.

Particle advection is the technique used to simulate the advection of particles in a particle system. It involves moving particles along a velocity field or flow field.

Z-buffering is not a type of volumetric rendering algorithm. It is a technique used in computer graphics to determine which objects are visible and which are hidden.
