Work with fields Collision effect: What is collision effect ? Make collide Make particle collision events Examples: Creating waterfalls Rain on car Field & Collision Effect 1) FIELD BASICS Field & Collision Effect 1) FIELD BASICS 1.1) What is field ? How to add dynamic field ? 1.2) Work with fields 1) FIELD BASICS 1.1) What is Field ? Fields You can simulate the motion of natural forces with dynamic fields For example, you can connect a vortex field to emitted particles to create swirling motion Types of fields Air fields Drag fields Gravity fields Newton fields Radial fields Turbulence fields Uniform fields Vortex fields Volume Axis fileds 1) FIELD BASICS Types of Field Fields - Air o An air field simulates the effects of moving air The objects you connect to the air field accelerate or decelerate so their velocities match that of the air as the animation plays o You can parent an air field to a moving part of an object to simulate a wake of air from the moving part 1) FIELD BASICS Types of Field Fields - Air o Wind: effects of wind o Wake: movement of air disrupted and pulled along by a moving object o Fan: a local fan effect o Magnitude: strength of the air field o Attenuation: strength of the field diminishes as distance to the affected object increases o Direction X, Y, Z :Specifies the direction the air blows o Speed: Controls how quickly the connected objects match the velocity of the air field o Inherit Rotation: rotating or parented to a rotating object, the air flow undergoes that same rotation o Component Only: direction specified by the combination of its Direction, Speed, and Inherit Velocity attributes o Enable Spread: Specifies whether to use the Spread angle o Spread : Represents the angle from the Direction settings within which objects are affected by the air field o Use Max Distance: connected objects within the area defined by the Max Distance o Max Distance: Sets the maximum distance from the air field at which the field is exerted 1) FIELD BASICS Types of Field Fields - Drag o A drag field exerts a friction or braking force on an object that’s animated with dynamic motion 1) FIELD BASICS Types of Field Fields - Drag o Magnitude: Sets the strength of the drag field The greater the magnitude, the greater the braking force on the moving object o Attenuation: Sets how much the strength of the field diminishes as distance to the affected object increases The rate of change is exponential with distance; the Attenuation is the exponent If you set Attenuation to 0, the force remains constant over distance o Use Direction: Specifies that the braking force is exerted only against the object’s velocity that lies along Direction X, Y, Z Available in the Attribute Editor only o Use Max Distance: If you turn on Use Max Distance, connected objects within the area defined by the Max Distance setting are affected by the drag field Any connected objects outside the Max Distance are not affected by the drag field Available in Attribute Editor only 1) FIELD BASICS Types of Field Fields - Gravity o A gravity field simulates the Earth's gravitational force It accelerates objects in a fixed direction Field & Collision Effect 2) COLLISION EFFECT 2.1) What is collision effect ? 2.2) Make collide 2.3) Edit connector 2.4) Make particle collision events 2) COLLISION EFFECT 2.3) Edit Connector Tesselation Fator: attribute represents the approximate number of polygons in the tessellated surface Reslience: sets how much the colliding particle’s velocity parallel to the surface decreases or increases as it bounces off the collision surface Friction: rebound occurs A value of makes particles collide with no bounce A value of causes particles to rebound fully Offeset 2) COLLISION EFFECT 2.3) Edit Connector Tesselation Fator 2) COLLISION EFFECT 2.3) Edit Connector Reslience 2) COLLISION EFFECT 2.3) Edit Connector Friction Field & Collision Effect 2) COLLISION EFFECT 2.1) What is collision effect ? 2.2) Make collide 2.3) Edit connector 2.4) Make particle collision events 2) COLLISION EFFECT 2.4) Make particle collision events Event effect in which two or more bodies exert forces on each other for a relatively short time Object Object 2) COLLISION EFFECT 2.4) Make particle collision events Create a collision event in Maya Field & Collision Effect 3) EXAMPLES Field & Collision Effect 3) EXAMPLES 3.1) Creating waterfalls 3.2) Rain splashing on the floor 3) EXAMPLES 3.1) Creating star effect Using Turbulence field Field & Collision Effect 3) EXAMPLES 3.1) Water poured into a glass 3.2) Rain on car 3) EXAMPLES 3.2) Rain on car This example is a form of Collision effect 3) EXAMPLES You can create it Thanks! ...
