PShape problem loading hi-poly OBJ

leota

Hi there, i'm coding a simple OBJ viewer using PShape. It is fine with models up to 165K polygons, but if I try loading an OBJ with more tha 300K polygons it crashes. Is there any way to handle this? BTW here's the code:

import processing.opengl.*;
import peasy.*; 
PeasyCam cam;

PShape model;

float ry;

public void setup() {
  size(1280, 720, OPENGL);
  model = loadShape("lowResGeo165.obj");
  cam = new PeasyCam(this, width);
  model.scale(20.0);
}

public void draw() {
  background(0);
  ambientLight(102, 102, 102);
  directionalLight(126, 126, 126, 0, 0, -1);
  directionalLight(126, 126, 126, 0, 0, 1);

  translate(width/2, height/2 + 100, 0);
  rotateZ(PI);
  rotateY(ry);
  shape(model);

  ry = 0;
}

koogs

add after line 11

println(model);

this will show you whether the loadShape has worked - if it's null then you can check for that. if it throws an exception you can catch that.

we can't test your code - the problem is the obj file which you don't supply...

I'm using the same obj, the lowres one loads fine the hires crashes. Here's the error I'm getting:

If you need I can provide the obj

amnon

Try going to File > Preferences and increasing your maximum available memory.

@amnon, thanks, that worked
