Hi again! 

Last time I was trying to rotate my ship by local coordinate system. So after rotation I was reading each rotation matrix and multiply (axis)vectors by them and results put to glRotatef function. Program works but rotations not... ship rotations is very strange... I don't know what is wrong in my idea so please help me 

Init code:
static Vector4f zaxis = new Vector4f(0,0,1,1);
         static Vector4f yaxis = new Vector4f(0,1,0,1);
         static FloatBuffer macierzz = BufferUtils.createFloatBuffer(64);
         static FloatBuffer macierzy = BufferUtils.createFloatBuffer(64);
       
//nowe wektory
static Vector4f zaxisd = new Vector4f();
static Vector4f yaxisd = new Vector4f();
//macierze
static Matrix4f zm = new Matrix4f();
static Matrix4f ym = new Matrix4f();Loop code:
                         GL11.glPushMatrix();
GL11.glRotatef(shipzrot,zaxis.getX(),zaxis.getY(),zaxis.getZ());
macierzz.clear();
GL11.glGetFloat(GL11.GL_MODELVIEW_MATRIX, macierzz);
macierzz.rewind();
zm.load(macierzz);
zm.transpose();

Matrix4f.transform(zm, zaxis, zaxisd);
Matrix4f.transform(zm, yaxis, yaxisd);

GL11.glRotatef(shipyrot,yaxisd.getX(),yaxisd.getY(),yaxisd.getZ());

macierzy.clear();
GL11.glGetFloat(GL11.GL_MODELVIEW_MATRIX, macierzy);
macierzy.rewind();
ym.load(macierzy);
ym.transpose();

Matrix4f.transform(ym, zaxisd, zaxis);
Matrix4f.transform(ym, yaxisd, yaxis);

GL11.glCallList(ship.getWskaznik());
GL11.glPopMatrix();

GL's  MODELVIEW_MATRIX is relative to the viewer, so it changes if the viewpoint changes, which is usually not useful! If you read it back, you got your ships transform relative to the camera, but not to your "space".


It would be quite cleaner if you manage your ship's transforms inside a Matrix4f only and apply it as whole with GL11.glLoadMatrix. Somewhat like

Matrix4f transformMatrix=new Matrix4f();

...

GL11.glPushMatrix();

---now update transformMatrix with your ship controls

transformMatrix.store(matrixBuffer);
matrixBuffer.flip();
GL11.glMultMatrix(matrixBuffer);

---draw the ship

GL11.glPopMatrix();


Thanks 
I resolved it about two days ago. Here is code without using Matrix4f:

private static void run(){
int licz=0;
//petla gry
while (gameRunning) {
         long a = System.currentTimeMillis();
         // wywoluj funkcje gamelogic
         GameLogic();
       
   
// czyscimy obraz i Depth Buffer
GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);         

GL11.glMatrixMode(GL11.GL_MODELVIEW);
GL11.glLoadIdentity();

cam.trans1(RotZ, RotY, PozY);
cam.update();
                     

if (licz != 0){
GL11.glLoadMatrix(m);
}

GL11.glPushMatrix();

GL11.glRotatef(shipyrot, 0, 1, 0);    
GL11.glRotatef(shipzrot, 0, 0, 1);
           GL11.glRotatef(shipxrot, 1, 0, 0);
           GL11.glTranslatef(0, 0, shipx);
   
           GL11.glGetFloat(GL11.GL_MODELVIEW_MATRIX, m);
   
GL11.glCallList(ship.getWskaznik());
GL11.glPopMatrix();

licz += 1;
                                  // now tell the screen to update
Display.update();

           // sprawdzamy czy uzytkownik niechce wyjsc, jezeli tak to wychodzimy z petli
           if (Display.isCloseRequested()) {
    gameRunning = false;
           Display.destroy();
           System.exit(0);
    }
    long b = System.currentTimeMillis();
    time = (int) (b-a);    
}        
}
