So, can I found where is my light source?. I have setposition and getposition method for light. Can I example getposition of light and set this position for object3d, ex cube - samething like marker? But How I can getposition of any object? getTranslation? .. When I add light source and not specify the position, it's in (0 0 0) ?

And other question. I lighting my scene but I haven't shadow. I found "setShadingMode" but I have no idea about this.

Sorry for my very begginer question, and Thanks very much.

I'm surprised. I think that I do not have big demands, so probably something I'm doing wrong. I have to go, but when I get home that I edit this post, I'll post my code and screens.

Hello. 
I found for solution of my problem but I don't know still. Is it possible samething like "multiple lights" in jpct-ae?
ex:

or

I was add two light to world, but I see only one. .

Hello
I'm try to do something like this: I have a object. I use a "getMaxPolygonID()" and result is 21 part of object. I want click on part of object (something like click on polygon number1, or better click on group of the poligon ex. (polygon1 + polygon2) and do whatever. I think about "Interact2D", "VisList" and "Polygon Menager" , but I have no idea about this. So my question is, How I can realize samething like:

1)Split object into pieces.
2)Group selected pieces to object

Or, maybe it's different way to do this.

PS. It's my four question, and I'm very glad of jpct support in this forum. It's very helpful and quick.

edit: I found a "getPolygonIDs" from CollisionEvent.. hmm it's what I want?

I have a class. This create the box with two textures. One of the textures is for "front" and other is for "back". Function reTexture repeat the texture. It's work great:

Now, i want add normal mapping to the texture, and i want "3d effect" of brick. I try make this very long time but the result is nothing.
my code :
public class Prostokat {

public Object3D createBox(final float width, final float depth,
final float height) {
final Object3D box = new Object3D(10);
final Object3D box1 = new Object3D(2);
Object3D box_suma;
final float x = width / 2;
final float y = depth / 2;
final float z = height / 2;

final int textureFactor = 512; //

final SimpleVector upperLeftFront = new SimpleVector(-x, -y, -z);
final SimpleVector upperRightFront = new SimpleVector(x, -y, -z);
final SimpleVector lowerLeftFront = new SimpleVector(-x, y, -z);
final SimpleVector lowerRightFront = new SimpleVector(x, y, -z);

final SimpleVector upperLeftBack = new SimpleVector(-x, -y, z);
final SimpleVector upperRightBack = new SimpleVector(x, -y, z);
final SimpleVector lowerLeftBack = new SimpleVector(-x, y, z);
final SimpleVector lowerRightBack = new SimpleVector(x, y, z);

int texIDw = TextureManager.getInstance().getTextureID("TexScianaW");
int texIDz = TextureManager.getInstance().getTextureID("TexScianaZ");
// front
box1.addTriangle(lowerLeftFront, x / textureFactor, 0, lowerRightFront,
0, 0, upperLeftFront, x / textureFactor, y / textureFactor); //zeby dobrze zorientowac normalne do mapowania tekstury musze o dobry kąt obrócić normalne , dlatego dziele przez texturefactor/ chyba ;/
box1.addTriangle(lowerRightFront, 0, 0, upperRightFront, 0, y
/ textureFactor, upperLeftFront, x / textureFactor, y
/ textureFactor);
box1.calcTextureWrapSpherical();
box1.build();
reTexture(box1, "TexScianaZ", 2f);

// back
box.addTriangle(upperLeftBack, x / textureFactor, 0, upperRightBack, 0,
0, lowerLeftBack, x / textureFactor, z / textureFactor,
texIDw);
box.addTriangle(upperRightBack, 0, 0, lowerRightBack, 0, z
/ textureFactor, lowerLeftBack, x / textureFactor, z
/ textureFactor, texIDw);

// upper
box.addTriangle(upperLeftFront, x / textureFactor, z / textureFactor,
upperRightBack, 0, 0, upperLeftBack, x / textureFactor, 0,
texIDz);
box.addTriangle(upperLeftFront, x / textureFactor, z / textureFactor,
upperRightFront, 0, z / textureFactor, upperRightBack, 0, 0,
texIDz);

// lower
box.addTriangle(lowerLeftBack, x / textureFactor, 0, lowerRightBack, 0,
0, lowerLeftFront, x / textureFactor, z / textureFactor,
texIDz);
box.addTriangle(lowerRightBack, 0, 0, lowerRightFront, 0, z
/ textureFactor, lowerLeftFront, x / textureFactor, z
/ textureFactor, texIDz);

// Left
box.addTriangle(lowerRightBack, y / textureFactor, 0, upperRightBack,
0, 0, lowerRightFront, y / textureFactor, z / textureFactor,
texIDz);
box.addTriangle(upperRightBack, 0, 0, upperRightFront, 0, z
/ textureFactor, lowerRightFront, y / textureFactor, z
/ textureFactor, texIDz);

// Right
box.addTriangle(upperLeftBack, y / textureFactor, 0, lowerLeftBack, 0,
0, upperLeftFront, y / textureFactor, z / textureFactor,
texIDz);
box.addTriangle(lowerLeftBack, 0, 0, lowerLeftFront, 0, z
/ textureFactor, upperLeftFront, y / textureFactor, z
/ textureFactor, texIDz);
box.calcTextureWrapSpherical();
box.build();
box_suma = Object3D.mergeObjects(box, box1);
box_suma.build();
return box_suma;
}
private void reTexture(Object3D obj, String t2, float tileFactor) {
Logger.log("ReTexturing...", Logger.MESSAGE);
PolygonManager pm=obj.getPolygonManager();
int t2Id=TextureManager.getInstance().getTextureID(t2);
int end=pm.getMaxPolygonID();
for (int i=0; i<end; i++) {
int t1=pm.getPolygonTexture(i);
SimpleVector uv0=pm.getTextureUV(i, 0);
SimpleVector uv1=pm.getTextureUV(i, 1);
SimpleVector uv2=pm.getTextureUV(i, 2);
TextureInfo ti=new TextureInfo(t1, uv0.x, uv0.y, uv1.x, uv1.y, uv2.x, uv2.y);

uv0.scalarMul(tileFactor);
uv1.scalarMul(tileFactor);
uv2.scalarMul(tileFactor);

ti.add(t2Id, uv0.x, uv0.y, uv1.x, uv1.y, uv2.x, uv2.y, TextureInfo.MODE_MODULATE);
pm.setPolygonTexture(i, ti);
}
Logger.log("ReTexturing...done!", Logger.MESSAGE);
}
}
I try connect this class with modyfied example "HelloShrader" but i can't.

Please help
