Hi list,
I've distilled the harukit example to just the glowing line for a lightsaber effect. My question is, is there a way to use it like the line object, ie glowingLine(0, 0, 200, 200)?
Thanks,
Justin

public int lmode = 2;
public int by = 8; //line thickness
PGraphics pg;
public color [] A;
float rr, gg, bb, dis;
int gain = 5;
float[] cc = new float[3];


void setup() {
  frameRate(3000);
  size(500, 500, P3D);
  loadPixels();
  A = pixels;
  pg = createGraphics(width, height, P3D); //offscreen graphics buffer for transparency
  colorMode(RGB, 350);
  hint(ENABLE_OPENGL_4X_SMOOTH);
  lights();
  noStroke();
  background(110);
  for(int i=0; i<3; i++) {
    cc[i] = random(40) + random(40) + random(40) + random(40) + random(40);
  }
}

void draw() {
  lights();
  stroke(255);

  for(int y=0; y<pg.height; y++) {

    for(int x=0; x<pg.width; x++) {
      // kx+=0.5;
      int pos = y*pg.width + x;
      //  int ka =int(ky)*pg.width+int(kx);
      color col = pg.pixels[pos];
      // color col =A[pos];
      rr = col >> 16 & 0xff;
      gg = col >> 8 & 0xff;
      bb = col  & 0xff;

      if( lmode ==1) dis = dist(mouseX,mouseY,x,y)/by; //spot
      if( lmode ==2) dis = dist(mouseX,mouseY,mouseX,y)/by; //lightsaber
      rr += cc[0]/dis-gain;
      gg += cc[1]/dis-gain;
      bb += cc[2]/dis-gain;

      A[x+y*pg.width] = color(rr, gg, bb);
    }
  }
    line(0, 0, 200, 200);
}
