Colorizing 3 Channel MSG Procedural…

Today’s post will continue the topic we started yesterday, looking at different approaches to colorizing MSG procedural imagery. Today we’ll look at using the ForceColorMap processor to colorize a 3 channel MSG procedural preset.

I started by using 3 GenAdvTurb processors to generate 3 different turbulence noise images, one for each of the 3 output image streams (ROut,GOut,BOut) as seen in the first 3 gallery images below. Note that each of the 3 GenAdvTurb processors outputs to a different output image stream.

The 4th gallery image shows what this kind of procedural color output looks like. Note that there’s a characteristic ‘look’ that is generated when 3 randomly correlated noise images are used for the 3 color channels of a procedural color image.

There are some special MSG processors that can be used to recolorize full color output, based on color gradients or color palettes. The particular one we’ll be looking at today is the ForceColorMap processor.

The 5th gallery image above shows how we modified out original simple 3 channel procedural preset to incorporate the ForceColorMap processor. Note that we’re using the 3 output image streams (ROut,GOut,BOut) for both the 3 input ports (In R,In G,In B) and the 3 output ports (Out R,Out G,Out B) of the ForceColorMap processor. The processors has 2 different input ports, which are hooked up to the ColorPalette and ColorPalette1 streams.

The 6th gallery image above shows the effect of colorizing the original simple MSG preset with the ForceColorMap processor. Note that we now have much more control over the range of colors used for the final procedural image output. And by editing the 2 color palettes we can generate an infinite variety of different colorizations for the procedural image.

The 2 gallery images above show mutated variations of our simple MSG preset in the Evolution Editor. The first image is using the ForceColorMap processor to colorize the output based on the 2 color palettes. The second image shows what we get when we turn off the ForceColorMap processor.

Note that all of the mutations generated without the ForceColorMap processor have a certain similarity to their look, while the first set of mutations generated with the ForceColorMap processor show off a great variety of different color styles (and are more visually interesting because of the more complex coloring in the various procedural images).

The SmoothColorMap processor is another processor that can be used to colorize a full color procedural image based on a single color palette stream.
