Static Glowing Animation

Hello Everyone,

I'm trying to make a static (in place) glowing animation for ellipse (static glowing animation like this, but with basic shapes not gif). For the glowing effect, I have found something close in this post. However, it will also blur the background. Is there a way to reset the filter?

I "think" what I need is draw (and not draw) the glowing object behind the actual object to make it seems like it's glowing. I checked out all the animation packages on the processing website, it seems like Ani can cycle through the glowing object repeated to create what I want. Does this sound like a reasonable approach? Any pointers on this would be much appreciated!

Thanks in advance.

Cheers,

Betty

You could use a transparent PGraphics to isolate the glowing shape.

Code Example

PGraphics pg;
void setup(){
size(200,200);
fill(0, 0, 255);
noStroke();
smooth();
pg = createGraphics(width, height, JAVA2D);
pg.beginDraw();
pg.smooth();
pg.background(255, 0);
pg.noStroke();
pg.fill(255,0,0);
pg.ellipse(100,100,95,95);
pg.filter( BLUR, 6 );
pg.fill(255,255,0);
pg.ellipse(100,100,90,90);
pg.endDraw();
}
void draw(){
background(255);
ellipse(mouseX, mouseY, 100, 100);
image(pg, 0, 0);
}
