The premise is: particle animation should impress. Moreover, it perfectly contributes to high-tech, geometric and businesslike aesthetics – naturally finishing them off. It is not something extraordinary, yet it has a certain wow factor. From the chaotic mess of tiny white dots that were scattered throughout the canvas, it transformed into a tool with great potential. Using Particle Animation to ImpressĪs time went by, the technique matured. While the concept by Robin Selmer is just a pleasant piece to watch the other two require the interaction of the user, and that’s always exciting.


Consider Particles in space by Dean Wagman, CSS only particle system by Robin Selmer and, of course, the push away effect skillfully reproduced and featured in a codepen of Alex Safayan. However, it does not mean that the approach is limited to just this sort of realization. It is a combination of particles and parallax that results in an engaging and dynamic aesthetic. For example, check out Canvas Particles by Romswell Roswell Parian Paucar.

These sands were shown to degrade the least and had little to no fines, and their particle shape was rounded to well-rounded. The best IAS sands were sourced from quarries located on rivers that had eroded volcanic outcrops. This accelerated ageing test method is applicable only to sands and not rubber or wood fibre IAS products. IAS degradation properties of fifteen IAS sands were tested including sand particle shape, sand particle distribution, percentage fines and sand particle degradation. This paper proposes an additional IAS test to eliminate sands that degrade above an established threshold rate after installation due to normal usage.

These fines and smaller particles tend to bind the sand and lower its impact attenuating performance. When children use the playground, sand degradation can occur when sand produces fines and smaller particles with low sphericity and angular which fill the voids between the sand particles. There is a deficiency with existing IAS test methods in that they do not take account of sand degradation over time. There are three primary IAS materials used, namely: granulated rubber products, wood fibre products, and sand. To lower the likelihood and severity of injury, impact attenuating surfaces (IAS) are installed within the impact area (fall zone). 8805-8805įalls within children’s playgrounds result in long bone and serious injuries.
