Scatter is one of the more complex of the filters we've done. In essence, it takes a group of images you provide it, and scatters them repeatedly over the source image. In depth, the controls you can use to set up how it scatters the 'particles' give it a wide range of uses.
Scatter allows you to set up a grid of images, 5 by 5, and provides controls to select the order in which those images are used when scattering. You can have it select which image using parameters such as strict ordering (one after the other), random, distance from the edges, or underlying colour properties of the source image.
When the particles are placed, their size, rotation, opacity, and colour properties can be adjusted based on various other parameters. For example, you could have the size of the particle adjusted based on its position in the source image, or a random value. The colour properties of the particle (H, L, and S) can be adjusted in a similar manner, even linked to the underlying image so that the particle takes on the base colour of the region on which it's sitting. These 'variants' give you a huge number of possible results, and allow you to do things like reconstruct an image from particles matched to its colour.
The placement of particles has a similar depth of control. You can have them placed randomly, left to right, top to bottom etc. You can even have them placed in a spiral, with control over how many branches it has, and how twisty they are.
Scatter can also generate procedural shadows for your particles, placing them correctly regardless of the scale and orientation of the individual particles. It supports alpha channels for the incoming particles, so you can have any shaped objects scattered over your image.
Scatter is perhaps the trickiest of our plugins to get in to. The controls are detailed, and push the envelope for what the current KPT UI model can do. Once you understand it though, the system can do anything from constructing clouds of butterflies, each unique, to reconstructing images from coloured marbles and candies. |
