v Maya offers a way to try this form of pc animation in which you set up the situations that you want to occur, then allow the software program solve a way to animate the items in the scene. With Particle effects, you may create the illusions of smoke, fireworks, rain, fire, and explosions.v With inflexible frame Dynamics, you may simulate real-world physical interactions among objects, consisting of collisions among surfaces. as an instance, you could simulate a bowling ball crashing through pins or simulate the effects of gravity when a ball falls to the ground. you may additionally simulate herbal forces, which include wind.v Dynamics is a branch of physics that describes how objects pass. Dynamic animation uses rules of physics to simulate natural forces. You specify the movements you want the object to take, then let the software figure out how to animate the item.v Dynamic animation lets you create a realistic movement that’s tough to gain with traditional keyframe animation. for instance, you can make effects together with tumbling dice, waving flags, moving cloth, rain, bubbles, fog, smoke and exploding fireworks.Ø Work with superior functions of particles such as substituting animated geometry for moving particleØ Use gravity and other force fields to animate particles, smooth bodies, and rigid our bodies.Ø Use emitters to release particles for effects consisting of steam, fire, rain, fireworks, and explosions.Ø We can Create, color, and animate particles in Dynamic. 4.2 Particles v Particles are points that show as dots, streaks, spheres, blobby surfaces, or other objects. you could animate the display and movement of particles with diverse techniques; for example, keys, expressions, and fields including gravity.v A particle object is a collection of particles that share the same attributes. you can create particle objects containing a single particle or thousands and thousands of particles. every particle in a scene belongs to some particle object.v Particles are points in 3D space that can be grouped collectively to create unique effects. To create particles in 3-D space, first choose the FX menuset from the Menuset drop-down list.Next, choose nParticles > Legacy particles > Particle tool from the menubar and click inside the viewport; a particle will be created in 3D space. via default, Maya creates one particle on a single click. l How you create particle :1. Particle Tool:Tool Settings (Particle device) window, choose nParticles > Legacy particles > Particle tool > option field from the menubar; the tool Settings (Particle tool) window might be displayed. Figure 4.1 : Particle tool Setting 2. Conserve:The Conserve attribute is used to control the motion of particles.3. Number of particles:The number of particles attribute is used to specify the number of particles to be created within the viewport with a single click on. The default value of this attribute is 1. if you specify a value more than 1 for this attribute, the maximum radius attribute underneath it will get activated. The maximum radius attribute is used to specify a spherical area wherein the specified range of particles might be randomly allotted.4. Create particle grid:The Create particle grid check box is used to create a grid of particles inside the workspace. To create a grid of particles, select this check field and click on once inside the viewport; a particle is created because the first point of the grid. next, click at a location this is diagonal to the first point and press enter; a grid of particles may be created. On selecting this test box, the Particle spacing attribute and the radio buttons in the Placement area may be activated.5. Set display attributes:l Set the render type of the particle object to select its form. For example, you can display particles as small spheres.l Color particlesl Make particles disappear as they age.6. Animate the particles:Set the position, speed, or acceleration attributes of particles. you can additionally set keys to animate a whole particle object’s translate, scale, and rotate attributes. 7. Render the particles:The last step is Rendering to make particle effects. It depends on the render type you select, you can render the particles with hardware or software rendering. Figure 4.2 : Rendering 4.3 Fields v Fields are forces that you use to animate the motion of particles, nParticles, nCloth, soft bodies, rigid bodies, fluids, and hair. A soft body is a polygonal surface, NURBS surface, NURBS curve, lattice, wire, or wrap deformer that you convert as described in Soft bodies. A rigid body is a polygonal or NURBS surface that you convert as described in Rigid bodies. You can create a field on an object or as a stand-alone force.v You can simulate the motion of natural forces with dynamic fields. as an instance, you may connect a vortex field to emitted particles to create swirling motion. 4.3.1 Create fields and connect objects to them v While you create a field, you usually also connect it to the objects you need the field to persuade. you can alternatively join objects to the field’s have an impact on after creation (see Dynamic relationship editor). so long as a connected object lies within the impact of the field, it is going to be affected by the field. you can upload a subject to selected CVs, edit points, vertices, or lattice points of an object inside the scenel Stand-alone fields:Stand-alone fields affect objects from a stationary or moving position inside the workspace.l Object fields:Item fields are owned by using an object and exert have an effect on from the item.l Extent fields:You may select a volume to define the region in space wherein particles or rigid bodies are affected by any field in Maya. 4.3.2 Types of fields 1. Air field:An air field simulates the effects of moving air. The objects you connect with the air field accelerate or decelerate so their velocities match that of the air as the animation plays. Air field option dialog box will be displayed here.
