Please help ;

error: invalid operands to binary expression ('fs::path' and 'const char *') [3]

Changing the line

writeImage( getHomeDirectory() + "BubbleChamber/" + toString( mNumSaveFrames ) + ".png", copyWindowSurface() );

in the Bubble Chamber app to

writeImage( toString(getHomeDirectory()) + "BubbleChamber/" + toString( mNumSaveFrames ) + ".png", copyWindowSurface() );

fixes the compiling error.

(modified) CinderTraer block missing from Annihilation

Just noting here in case anyone wonders why that project doesn't work straight outta github.

can someone explain those lantern shaders in flocking app?

I tried that shader in shaderfrog here. Some thing looks wired about it. I also tried to use it in processing. here is what it looks like .
black cube is the light position.
one thing that seems wrong is when cube goes behind the sphere the red blob does not go back. I think its because in code mvpMatrix of cam is passed to shader but I am not getting it how to access mvpMatrix of camera in processing. it must be that problem that is causing the anomaily.
Hey robert please don't mind I am just trying to understand the shader. :) your work always amaze me and I love it just trying to understand how you create those visuals. I know its hard for you to explain the code but I would appreciate if some one might do that. Just learning shaders.

PShader lantern;

void setup() {
  size(700  , 600, P3D);
  noStroke();
  fill(204);
  lantern = loadShader("frag.glsl", "vert.glsl");
  float z =(height/2.0) / tan(PI*30.0 / 180.0);        //default camera pos for processing
  //println(z);
  lantern.set("eyePos",width/2.0, height/2.0, z);  //default camera pos for processing
  lantern.set("roomDim",7000.0,7000.0,7000.0);
  lantern.set("mainPower",05.99);
  
}
float t=0;float r=173;// ticker and radius of sphere
void draw() {
  float dirY = 0;
  float dirX = r*sin(t*2*PI);
  float dirZ = r*cos(t*2*PI);
  lantern.set("lightPos",-dirX,-dirY,dirZ,0);  //setting light pos for the shader 
  shader(lantern);          
  background(0);
  t+=0.01;
  translate(width/2, height/2,0);                 //moiving to center of screen
  //fill(255);
  //directionalLight(20, 204, 204, -dirX, -dirY, dirZ);  // setting directional  ,not need for this shader
  for(int i=0;i<1;i++){         //for if you wanted to create multiple spheres
  fill(120,100,80);
  pushMatrix();
  translate(0, 0, 0);           // translate multiple spheres to different positions : set the random values or some calculated locations(x= rad*sin(theta), y= rad*cos(theta))
  sphere(170);                   //main sphere with shader
  //box(900,900,0);
  popMatrix();
  }

  resetShader();
  pushMatrix();
  translate(-dirX, -dirY, dirZ);
  fill(255,0,0);
  box(10,10,10);           //virtual light box , just to see where the light is.
  popMatrix();
