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.
The image below shows the MSG Advanced Editor processor chain used for generating the adaptive screening effect above.
Note that the effect is very similar to the one examined in detail yesterday. What is different is that the processors associated with generating the space filling curve and compositing it with the source edge map have been removed. So the adaptive halftone screen is purely based on the source edge map generated by the TexFv and Threshold processors, as shown in the first gallery image below.
The 2nd gallery image above shows the distance map image generated by processing the 1st gallery edge map image with the 1toFloatChamferDist and 1DMapFloatChamDist processors. Note that the grayscale gradient patterns radiate outwards from the original source edge features. By adjusting the controls associated with the 1DMapFloatChamDist processor you can change the freuqncy of the radiating patterning effect.
The last gallery image above shows the color halftone output prior to the ForceColorMap processor. This processor takes the 3 color binary halftone image and color maps it using 2 color palettes. The image below shows how you can use the Evolution Editor to generate various mutations of this adaptive screening effect. Note that the patterning can be changed as well as the color palette based mapping associated with the final effect.
