Initial position the object with Proscene in Processing

Jose_Aparecido

Hello guys,

I'm trying to combine the use of toxilibs and proscene libraries to view objects in a scene.

How could I set the initial positions of the object? (More to the middle of the screen, and a certain angle - straight for example).

I'm trying to combine more than one command, but it looks like a interfefe on the other, one could give any tips?

Below is the code and the image, to pass a better idea I'm trying to do.

Note: You need a .stl file to render and libraries, of course ...

Code import toxi.geom.*; import toxi.geom.mesh.*; import toxi.processing.*; import remixlab.proscene.*; import remixlab.dandelion.core.*; import remixlab.dandelion.geom.*;

float p1 = -1, p2 = -50, p3 = 30, p4 = -15;

int nbPart         = 2000;
boolean avoidWalls = true;
//int flockWidth = 1280, flockHeight = 720, flockDepth = 600;

PVector pCam;

void setup() {
  size(displayWidth, displayHeight, OPENGL);
  surface.setTitle("Corpo Humano");
  noStroke();
  //smooth();
  //lights(); //Inicia Luzes

  pCam = new PVector(-1, -50, 30);

  //Inicia ambiente para Cena
  scene = new Scene(this);
  scene.setAxesVisualHint(false);
  scene.setGridVisualHint(false);
  scene.addAnimationHandler(this, "animateScene");
  scene.setAnimationPeriod(40); // 25Hz
  scene.mouseAgent().setPickingMode(MouseAgent.PickingMode.CLICK);

  //scene.setBoundingBox(new Vec(0, 0, 0), new Vec(flockWidth, flockHeight, flockDepth)); //
  //scene.camera().setTranslationSensitivity(-10);
  //scene.camera().frame().setRotationSensitivity(1.5);
