Okay, I have the paint strokes streaming along simultaneously but I can't get the canvas to fill up from edge to edge. The source i am using is a 1920 x 1080 TIFF file that has color over its entirety, and I created a path from the source that entirely fills the 1920 x 1080 canvas, which I see in Bezier mode. But when I auto-paint, the canvas remains blank along the left edge.
How might I get the entire canvas to fill with paint over time?
Thanks for the help.
I you want to export the bezier path frame you are using i can take a look at it. It's hard to comment on anything otherwise.
Here you go.
What exactly is your goal for this preset. Do you want the bezier paths you just uploaded to paint in?
Hey John. I want the canvas to very gradually fill up with multiple simultaneous painting strokes until the entire screen is full. It is working mostly as needed except that there is always a fairly large area on the upper left of the canvas that receives no paint and stays black.
I would also like to understand why exactly the canvas is not getting completely filled with paint so I can better tweak future presets.
Your original paint preset picks a random path start point. Then is uses the random path scan setting to build a set of additional path start points derived from the random path picekd from path memory 1. So additional start points are then generated off of that random selected path (offset by the original random generator position). Until that path has been transversed, then another random start point is selected.
the actual painting is based on the path shape controls, which are using a curved path type based on source orientation (path angle control panel). So the paths being generated have nothing to do with the bezier paths you dumped into path memory 1. if you just use a simple Point Scan i think you will actually get better coverage. use an inhibitor to restrict path starts to non painted areas of the canvas if you want to speed up coverage.
Symmetric (Sym) for the Symmetry parameter works better for path shape settings (as opposed to Non Sym for Symmetry) if you want to do a better job of full coverage. With a symmetric setting, the path start point is used as the center of the generated path, which essentially grows from that start point at 180 degree offset. Non Sym starts path generation at the start point. So based on the source orientation, it might never fill in certain areas.
Thanks John, looks like that nailed it
Btw, is there a particular parameter or set of parameters that allow this preset to have multiple simultaneous strokes of paint appearing on the canvas? That technique is something I have been trying to generalize forever. I had played with the pen tracking param some time back but that is not being used here. So is there a general set of params to make that occur?
Particle pen mode is the one with multitple simultaneous paint particles drawing at the same time (in normal action painting).
The other approach is to use time particles, usually with a path length of 1 so you just are seeing the paint nib, and the multiple painting occurs when you run the time particles in loop action. So each time particle is one of the simultaneous paint paths, and the actual painting occurs over multiple cycles in loop action.
I wanted to turn this question around a little. So, what kind of additional multi-path painting behavior should we be thinking about, or adding to Studio Artist in the future? As opposed to the 2 options i mentioned above to answer your initial question.
