1.1.1) What is Emitters ?
Emitters generate moving or stationary particles as an animation plays. Youcan use emitters to create smoke, fire, fireworks, rain, and similar objects.

Types of emitters:
o Point emitters (directional and omni) emit particles from a position inthe workspace or from particles, vertices, CVs, edit points, or latticepoints.
o Surface emitters emit particles from random, evenly distributedpositions on the outer faces of NURBS or polygonal surfaces.
o Curve emitters emit articles from random, evenly distributed positionsof a NURBS curve.
o Volume emitters emit particles from a closed volume. You can choosefrom cube, sphere, cylinder, cone and torus.

The tools used to create and control Emitters
o Basic Emitter Attributes.o Distance/Direction Attributes.o Basic Emission Speed Attributes.o Volume Emitter Attributes.o Volume Speed Attributes.
1.2.1) Basic Emitter Atributes.
Emitter type : Select one of these choices from the pop-up menu
o Omni: Sets the emitter type to anomnidirectional point emitter.
o Directional: Sets the emitter type to adirectional point emitter.
o Surface: Emits particles from randomlydistributed positions.
o Curve: Emits particles from randomlydistributed positions on or near a curve.
o Volume: Emits particles from a closed volume.

Rate (Particle/Sec): average rate at which particles are emitted per second. Scale Rate by Object Size: the size of the object emitting the particles affects the rate of particles
emitted per frame. Need Parent UV (NURBS Surface emitters only): adds parentU and parentV attributes to the particle
shape and sets the needparentUV attribute to on. Cycle Emission: Cycle Emission lets you restart the random number sequence of the emission. Cycle Interval: Defines the interval in frames for restarting the random number sequence when
using Cycle Emission.

Note: difference between created Emitter by “Create Emitter” and “Emit From Object”.
Min Distance : Sets the minimum distance from the emitterat which emission occurs.
Max Distance: Sets the maximum distance from the emitterat which emission occurs.
Direction X, Y, Z : emission direction relative to the emitter’sposition and orientation. Available only for directional, curve,and volume emitters.
Spread : emission spread angle. A value of 0.5 is 90 degrees,a value of 1 is 180 degrees. Available for only Directional andCurve emitters.

Speed : Sets a speed multiplier for the original emission speed ofthe emitted particles.
Tangent Speed : magnitude of the tangent component of emission speed for surface and curve emission.
Normal Speed : magnitude of the normal component of emission speed for surface and curve emission.

Speed Random : Speed Random attribute lets you addrandomness to your emission speeds without using expressions.Each particle’s speed is a random value between:
Speed - Speed Random/2 Speed + Speed Random/2
1.2.2) Distance/Direction Atributes.
Use the Attribute Editor instead of the Channel Box.
Volume Shape: Specifies the shape of the volume that theparticles are emitted into.
Volume Offset: Offsets the emitting volume from thelocation of the emitter.
Volume Sweep: Defines the extent of rotation for allvolumes except cubes. This can be a value between 0 and360 degrees.
Section Radius (Torus only): Defines the thickness of thesolid portion of the torus, relative to the radius of thetorus’s central ring.
Die on Emission Volume Exit: the emitted particles diewhen they exit the volume.

Apply only to the initial velocity of the particles. Away From Center: move away from the center point of cube or
sphere volumes. Away From Axis: particles move away from the central axis of
cylinder, cone, or torus volumes. Along Axis: move along the central axis of all volumes. Around Axis: move around the central axis of all volumes. Random Direction: adds irregularity to the direction and initial
speed of the particle’s Volume Speed attributes, somewhat likeSpread does for other emitter types.
Directional Speed: adds speed in the direction specified by theDirection XYZ attributes of all volume emitters.
Scale Speed by Size: increase the size of the volume, the speed ofthe particles increases.
