grid of boxes with random sizes..

Hello,

I am trying to build a grid of boxes, which i can view in 3d with peasy cam.. My problem is that I would like to have random sizes, but only with a trigger every time I want and not in a loop.. To use peasy cam you need to update the boxes inside draw() but how can I use a random function outside side the loop, so the random sizes can be fixed after a random trigger? As you can see in the following code, the size is constanlty changing within a loop..

Thank you in advance!!

import processing.opengl.*;

import peasy.*;

PeasyCam cam;

void setup() {

        size(800, 800, OPENGL);

    noStroke();

cam = new PeasyCam(this, 1800);

cam.setMinimumDistance(10);

cam.setMaximumDistance(1800);



}

void draw() {

      lights();

        background(0);



translate(0, 0, 0);

       for (int x = 0; x <= width; x += 120) {

for (int y = 0; y <= height; y += 120) {

                   pushMatrix();

translate(x, y);

                   box(30,30,random(0.2,50));

popMatrix();



}



}

}

Hemesh OBJ export

Hello!

I have the following code that I found on the web to make 3D Voronoi, how can I export to Obj? Can anyone please help?

import wblut.processing.*;

import wblut.hemesh.creators.*;

import wblut.hemesh.core.*;

import wblut.geom.*;

import processing.opengl.*;

import wblut.hemesh.modifiers.*;

import wblut.hemesh.tools.*;

float[][] points;

int numpoints;

HE_Mesh container;

HE_Mesh[] cells;

int numcells;

WB_Render render;

void setup() {

  size(800,800,OPENGL);

  hint(DISABLE_OPENGL_2X_SMOOTH);

  hint(ENABLE_OPENGL_4X_SMOOTH);

  smooth();

  //create a container mesh



  container=new HE_Mesh(new HEC_Box().setWidth(400).setHeight(400).setDepth(400));



  //generate points

  numpoints=200;

  points=new float[numpoints][12];

  for(int i=0;i<numpoints;i++) {

   points[i][0]=random(-250,250);

   points[i][1]=random(-250,250);

   points[i][2]=random(-250,250);

  }



  // generate voronoi cells

  HEMC_VoronoiCells multiCreator=new HEMC_VoronoiCells();

  multiCreator.setPoints(points);

  // alternatively points can be WB_Point[], any Collection<WB_Point> and double[][];

  multiCreator.setN(190);//number of points, can be smaller than number of points in input.

  multiCreator.setContainer(container);// cutoff mesh for the voronoi cells, complex meshes increase the generation time

  multiCreator.setOffset(0);// offset of the bisector cutting planes, sides of the voronoi cells will be separated by twice this distance

  multiCreator.setSurface(false);// is container mesh a volume (false) or a surface (true)

  multiCreator.setCreateSkin(true);// create the combined outer skin of the cells as an additional mesh? This mesh is the last in the returned array.

  multiCreator.setUseDummy(false);

  // can help speed up things for complex container and give more stable results. Creates the voronoi cells for a simple box and

  // uses this to reduce the number of slicing operations on the actual container. Not fully tested yet.



  cells=multiCreator.create();

  numcells=cells.length;



  render=new WB_Render(this);





   for (int i = 0; i < numcells; i++) {



   HEM_Lattice lattice = new HEM_Lattice().setWidth(26).setDepth(6);

   cells[i].modify(lattice);









   }





}

void draw() {

  background(255);

  directionalLight(255, 255, 255, 1, 1, -1);

  directionalLight(127, 127, 127, -1, -1, 1);

  translate(400, 400, 0);

  rotateY(mouseX*1.0f/width*TWO_PI);

  rotateX(mouseY*1.0f/height*TWO_PI);

  drawFaces();

  drawEdges();

}

void drawEdges(){

  smooth();

  stroke(0);

  for(int i=0;i<numcells;i++) {

   render.drawEdges(cells[i]);

  }

}

void drawFaces(){

  noSmooth();

  noStroke();

  fill(255);

  for(int i=0;i<numcells;i++) {

   render.drawFaces(cells[i]);

  }

}

SuperCollider and Processing

Hello people,

I found many examples about drawing a waveform real time in processing from supercollider buffers, but I would like to make a static one, like the SoundFileView object in supercollider. I would like to get the values from a buffer in supercollider and draw a waveform of the entire sound file, so I can then place cursors on the waveform to control sample position, select a range etc. Can anyone please help? :)

(sorry that I post this topic again with a different account, but i had a problem and I had to change it.. )
