Sorry for my mistake

Here are the links :

EDIT :

I am thinking of a thing : Can I simply get axises mesh's point, thus I can set the Object3D.SetCenter() stick the the mesh's point (sorry for bad english).

Ok, thanks, I'll try it now.

And, yes, I put my tree above the ground to make sure the collision is computed.

I'll tell you if it works.

Nope, stille the same result...

I give you the new code :

I'm giving up, if I don't succed, I put the trees by hand.
Nah, I'll play with variable settings tomorrow.

The problem is that the trees are floating above or under the terrain, depending the initialisation location.

dir is a SimpleVector(0, 1, 0).

I tried various values of this, nothing changes...

PS : Look at the zip attached to my previous post for more details.

Thanks.

Hi all !

It's been two days I try to make collisions works. Unsuccessfully...

I load a 3ds terrain and want to stick 3ds trees on it.

Here's the project (simplified) : https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0B34S8VzVRdKMMGQxY2UwNDItNWM2OC00YzdkLTlmZmEtMjNjNDg3NmIwZWMz&hl=fr

The important code parts are :


ground = Loader.load3DS("res" + c + "ground.3ds", 70f)[0];
ground.rotateX((float) (-Math.PI / 2));
ground.translate(-100f, 10f, 2f);
ground.setSpecularLighting(true);
ground.setShadingMode(Object3D.SHADING_GOURAUD);
ground.setTexture("ground");
ground.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS);
ground.setCollisionOptimization(Object3D.COLLISION_DETECTION_OPTIMIZED);
ground.build();
world.addObject(ground);


And :


public TreeEngine(World world, Object3D ground)
{
char c = File.separatorChar;

Object3D tree = Loader.load3DS("res" + c + "tree.3ds", 3f)[0];
tree.setSpecularLighting(true);
tree.setShadingMode(Object3D.SHADING_GOURAUD);

trees = new Vector<Object3D>();
for (int i = 0; i < 25; i++)
{
trees.add(tree.cloneObject());
trees.get(i).rotateX((float) (-Math.PI / 2));
trees.get(i).rotateY((float) (-Math.PI / Math.random() * 2));
//trees.get(i).scale((float) Math.random() * 2f);
trees.get(i).setCenter(ground.getTransformedCenter());
trees.get(i).translate(new SimpleVector(Math.random() * 800f - 400f, 0, Math.random() * 800f - 400f));
trees.get(i).setCollisionMode(Object3D.COLLISION_CHECK_SELF);
trees.get(i).setCollisionOptimization(Object3D.COLLISION_DETECTION_OPTIMIZED);
trees.get(i).build();
world.addObject(trees.get(i));

dir = trees.get(i).checkForCollisionEllipsoid(dir, new SimpleVector(1, 1, 1), 1);
//System.out.print(dir);
trees.get(i).translate(dir);
}
}


Did your expert eyes seen something wrong on this ?

Btw I set "Config.collideOffset = 40;".

Thanks in advance.
