Recursive MSG Abstract Animation

The following image is a frame capture from an animation generated by running a MSG preset in loop action into an open movie stream. The processing is recursive, which means that the output of the previous MSG processing cycle is used as the input to the current MSG processing cycle. This post extends on the ideas presented in our post 3 days ago (Jan30th) on Simple MSG Procedural Abstract Animation.

The image gallery below shows the MSG Advanced Editor settings used for the MSG preset that created the animation discussed in this post. The gallery images show off the IO (input-output) connections used for several of the processors.

Note that the first 3C Frame CP processor is using the 3 input streams for the MSG effects (RSrc,GSrc,BSrc) as the input to the processor. If you look at the very last image in the gallery you will see that the IP Source for the MSG preset is the Current Layer, so this is what is setting up the recursive processing going on in each cycle in the developing animation. The previous output frame image is used as the input to the effect for the current processing cycle. The animation starts with a black canvas for the first cycle of the animation.

The 3C Frame CP processors overlays a vector frame effect onto it’s input streams. The coloring comes from a color palette stream, which is what the CP in the processor name stands for. The CP shortcut in MSG processor names always stands for Color Palette, and the CG shortcut in MSG processor names always stands for Color Gradient.

Note in the progression of gallery images shown above that the same IO routing strategy discussed in the previous post in this series. A 3C Rotate processor is used to rotate the output streams and that rotated output is routed to 3 temporary image streams. The original output and then temporary rotated output are then combined back together again using a 3C Composite processor. This editing motif happens twice in the processor chain editor.

The MSG preset used for this example includes an additional 3CRotateScale processor. Note that the IO routine for this processor uses the same strategy discussed above. It’s output is routed to the 3 temporary image streams. Those 3 temporary image streams are then used as input to the final SmoothColorMap processor, which routes it’s output to the effects 3 output streams (ROut,GOut,BOut).

I added the 3CRotateScale processor to generate a pull in attractor into the recursive processing, which is a technique we’ve discussed here before in other contexts.

The final abstract animation can be seen here. I did a little hand editing of the hue of the color palette used for the effect in real time as the loop action streaming to the open movie stream was outputting in real time.

I also created a second example, using a different set of mutated MSG presets based on the original post in this series. That second animation example can be seen here. I used the Evolution Editor in real time to mutate the current MSG preset running in loop action mode into the open movie stream in real time when building this other animation.
