Particle Goal

1) OVERVIEW PARTICLE GOAL

1.1) Goal ?

PARTICLE GOAL

Working with Particle Goal ( A goal is an object that particles follow or move towards Youcan use goals to give trailing particles a flowing motion that’s hard to generate with otheranimation techniques The trailing particles move as if connected to the goal by invisiblesprings In the context of goals, soft bodies are considered particles )

1.2) What is Particle Goal ?

PARTICLE GOAL

Particle objects are useful as goal objects because of the many techniques available foranimating particle motion You can’t add a goal to individual particles of the particle object,but you can control how influential each particle is on the trailing object

If the goal is a particle object, its particles attract the particles of the trailing object one forone as the animation plays If particles in the objects do not die, the trailing particles followgoal particles based on the creation order

If particles in either object die, the preceding scheme no longer applies You can no longervisually predict which trailing particle will follow a particular goal particle

If the trailing particle object has more particles than the goal object and particles don’t die ineither object, the extra particles follow the first-created particles of the goal

For instance, suppose you create a goal object with two

particles and a trailing object with four particles The four

particles would move toward the two particles like this:

1.3) What is Multiple goals ?

If the goal weights differ, each goal object attracts the trailing object with different strength The trailing object comes to rest at a position closer to the goal with the higher goal weight.

1.4) What we can do with Particle Goal ?

1.5) Create a Particle Goal

PARTICLE GOAL

 Step 1:

o Select the particle object you want to be affected by the goal

o To select a soft body rather than a conventional particle object, you canselect the soft body’s original geometry or its child particle object

 Step 2: Shift-select the object you want to become the goal.

 Step 3: Select Particles > Goal

 Step 4: To adjust the goal’s influence, see Edit goal attributes.

 Step 5: Play the animation to see the particles move towards the goal.

1.5) Create a Particle Goal

1 moves the trailing particles to the goal object position immediately

 Use Transform as Goal:

o Makes particles follow the object’s transform rather than its particles,CVs, vertices, or lattice points
