Modifying Yesterday’s Smart Screening to Emulate a Woodcut Screen Effect
Yesterday we showed how to use the paint synthesizer to build a smart random screen halftone effect. today we will show how a simple editing change in the paint synthesizer can change the effect to emulate a woodcut screening or litho print effect.
Building a Smart Halftone Screen Using the Paint Synthesizer
The real power of Studio Artist is that it’s an extremely user configurable environment for building custom visual effects. In today’s post, we’ll take a look at using the paint synthesizer to build smart halftone screens, which can then be used in a PASeq to build custom halftone screening effects.
Simple MSG LineScreen Halftone Effect
Since we’ve been on a thread with recent posts discussing exotic halftone processing using space filling curves as halftone screens, i thought it would be instructional to put together a much simpler traditional line screen color halftone effect. This post will show you how to build this simple MSG effect, and might provide some additional insight into the more exotic processing used in the examples shown over the past few posts.
Making the Hilbert Adaptive Halftone Effect a Vector Effect
See the full gallery on Posterous We’re returning to the MSG effect we discussed 2 days ago, which generates a Hilbert space filling curve adaptive halftone effect with built in colorization. The MSG effect itself generates raster image output. In today’s post we will show how you can convert this effect into one that generates vector output, which allows for resolution independent printing (on a billboard sized canvas with full detail if you wanted to). The first image in the gallery above shows the MSG effect, the second shows the effect output as an EPS file and zoomed into using Apple’s Preview application to show that when the effect is output as a vector file it can be scaled up without aliasing effects since all of the information in the effect is composed or resolution independent vectors. The third image shows a similar 600% magnification of the original raster effect, note how different it looks when compared to the vector magnification in the 2nd gallery image.
Adaptive Chamfer Distance MSG Halftoning Effect
Today’s post continues the thread we’ve been following for the last 2 days. This post will show a modification of yesterday’s MSG processing effect with the space filling curve part removed. So the effect is purely based on an adaptive halftone screen generated from the source image edge map and some additional chamfer distance map processing.
Hilbert Curve Adaptive Halftone Screen Effect
Today’s post continues the thread we started yesterday. In yesterday’s post we showed 2 different approaches to building halftone screen effects based on space filling curves. Today we show how to build an adaptive halftone screen effect based on a variate of a Hilbert space filling curve. Adaptive halftone screening means that the halftone screen is not just purely geometrical but also derived from some form of source image modulation, leading to a screening effect unique to a given source image.
Building a Halftone Screen with a Space-Filling Curve
Studio Artist 4.03 has some cool new MSG processors that generate space-filling curve based effects. One fun thing you can do is to generate a halftone screen based on the space-filling curve. We’ll take a look at how to build this effect in today’s post.
