First, create a new solid, the same size as the composition you are working in. If you end up doing this kind of work professionally, Particular is absolutely worth investing in – but you can still do a lot with After Effects’ built-in Particle World and it’s the perfect tool for learning the basics.ĬC Particle World is an effect, which means it needs to be applied to something. It offers more advanced controls and options than the built-in effects do, but it doesn’t come cheap: Particular by itself costs several hundred dollars and the entire collection of Trapcode effects runs around a thousand. Of all the many effects, scripts, and presets that can be added to After Effects, Particular is easily one of the most popular. Trapcode encompasses a suite of effects made by the third-party company Red Giant. If you do any online searches for particle techniques in After Effects, you will probably see another effect mentioned a lot: Trapcode Particular. Many of the options in Particle World can be applied to the other particle simulation effects as well, so learning this one will give you a good head start on using the others. We’re going to be focusing on CC Particle World, since it’s the only effect that works in a 3D environment. If you look under the “Simulation” section of the effects, you’ll see that there are actually a few different particle-related options: CC Particles Systems II, CC Particle World, and Particle Playground. Even as a purely abstract aesthetic element, particles can add a lot to a composition. Particles can be used to create all sorts of interesting effects, including rain, snow, smoke, flames, fireworks, stars, and a lot more. Let’s explore one last 3D topic with one of After Effects’ coolest features: particles. Usually comes from motor vehicles driving on unpaved asphalt and cement roads, crushing and grinding of materials, and dust raised by the wind.So far, we’ve created 3D objects, cameras, and lights in After Effects. PM10: PM10, also known as respirable particulate matter, refers to particulate matter with an aerodynamic equivalent diameter of ≤10 microns. PM2.5 is mainly smog and dust from roads in daily life. Human health and atmospheric environmental quality have a greater impact. It is easy to attach toxic and hazardous substances (for example, heavy metals, microorganisms, etc.), and it has a long residence time in the atmosphere and a long transportation distance. PM2.5: PM2.5 has a small particle size, large area, and strong activity. PM1 mainly comes from the burning of fossil fuels, such as coal and VOCs. The main source of PM1 is mainly daily power generation, industrial production, indoor environmental pollution, etc., which is difficult to judge by the naked eye. What is the difference between PM10, PM2.5 and PM1.0? For comparison, the average diameter of human hair is 50-70 µm. In the context of air quality issues, particulate matter is particularly important.įine particles such as PM10, PM2.5, and PM1 are defined as parts with aerodynamic diameters of less than 10, 2.5, and 1 µm (information: 1 µm = parts per million) meters or thousandths of a millimeter ). The aerodynamic diameter of a dust particle is the diameter of a spherical particle, and the diameter of the spherical particle shows the same behavior as the dust particle in ambient air (not necessarily having a spherical shape). The floating fabric is generally classified according to "aerodynamic diameter". They are usually classified as "suspended matter" and are often referred to as PM (abbreviation of "Particulate Matter" in English). These particles (suspension, liquid or solid) with different compositions and sizes are sometimes called "aerosols". In addition to gaseous pollution, the surrounding air may also be polluted by particles.
