Support / Is it possible to postpone the garbage collection?
« on: July 20, 2012, 05:39:18 pm »
Hi, I need to load 3D models which are of relative large size (1MB-10MB). The loading of an object takes a long time (20 sec for a model of 1.5MB), when I look at the logs I see that the garbage collector is constantly freeing memory and pausing. See below for a few logs:

Code: [Select]

Is it possible to let the garbage collector free memory after the model is loaded?

Thanks

Support / while dragging, object moves faster than finger
« on: June 24, 2012, 03:41:06 pm »
Hi

I have a problem with touch gestures using jPCT-AE. When I want to drag an Object3D, the object moves faster than my finger. I use following code:

Code: [Select]
public boolean onTouchEvent(MotionEvent me) {
if (me.getAction() == MotionEvent.ACTION_DOWN) {
xpos = me.getX();
ypos = me.getY();
return true;
}

if (me.getAction() == MotionEvent.ACTION_UP) {
xpos = -1;
ypos = -1;
                        dragging = false;
moveX = 0; //used for dragging
moveY = 0; //used for dragging
return true;
}

if (me.getAction() == MotionEvent.ACTION_MOVE) {
float xd = me.getX() - xpos;
float yd = me.getY() - ypos;

              xpos = me.getX();
ypos = me.getY();

dragging = true;
moveX = xd; //used for dragging
moveY = yd; //usedf or dragging
return true;
}

try {
Thread.sleep(15);
} catch (Exception e) {
// No need for this...
}

return super.onTouchEvent(me);
}

public void onDrawFrame(GL10 gl) {
        if(dragging){
cube.translate(0, moveY, 0);
cube.translate(moveX, 0, 0);
dragging = false;
        }

}

Any suggestions on how I can keep the object under my finger?

PS: I'm fairly new to this library, but I really like it so far!! Great job!
