Particles systems are used to create multiple objects that moveover time.

Used to stimulate rain, snow, blowing sand and smoke, or anythingthat involves numerous small objects.

Two common features of particles systems is:

Emitter Non-rendering object use as the location where the particles begin their lives.Variety of shapes, including planes, boxes, cylinder, and emitter-specificicons.

ParticlesThe real meat of a particle system.How the particles looks known as the type of particles emitted.2D particle shape, called facing particle (square shape)3D particle shape.

Three types of 3D particles :

Standard shapes (Triangles, stars, tetrahedrons, cubes, andspheres)

Metaparticles (based on metaball technology)

Instance geometry (Substituted particles with any 3D objectin a scene) at rendering time.

Six types of particles systems is:

3. Spray

Basic particle system.Particles are emitted from a plane-shaped emitter (tetrahedronor facing particles).

4. SnowSimilar to spray particle system.Has a tumble factor to each 2D particle emitted.Enable star, triangle, or facing particles to rotate randomly infalling snow or billowing leaves.

1. Super SprayHas large amount of control over emission, motion, and type of particles.

2. BlizzardUpdated version of snow particle system with much of thecontrol found in the Super Spray.

3. PAarrayUse existing geometry object in the scene as the emitter.Particles can be emitted from the objects edges, vertices, or faces.

2. PCloud

Restricts the loction of the particles to the volume of Pcloudicon or a selected geometry object.

Creating particles object by using several types of particlessystems (Using spray, snow and super spray)

Render the result into .avi file format.

Two tools that can be used to alter the particles direction isspace warps and deflector.

4. Space warps

Non-rendering object that can influence the appearance of geometry or the motion of the particles in a particle system.Altering the direction and speed of the particles.Example : Force (Wind, gravity, drag, PBomb and etc..)

Particles Direction Alteration

2. Deflector

Cause particles that impact the deflectors to bounce at thereciprocal angle that they hit the deflector.

Deflectors are planar and SDeflectors are spherical, whileUDflector allows the selection of a scene object to act as a

deflector.

2. Changing particles objects direction by using tools thatcause particles objects direction alteration (Space Warpsand Deflectors)

4. Render the result into .avi file format.
