humm that seems to look at the backBuffer and then use the alpha or
something. so don't look like its the gluProject() I need.

I need to no where my objects are after turning, I do this :

gl.glPushMatrix();

    gl.glTranslatef(10f, 0f, 0f);
    gl.glRotatef(180f, 0f, 1f, 0f);

    float[] mat = new float[16];
    gl.glGetFloatv(GL_MODELVIEW_MATRIX, mat);
                   
    sOne.newx = mat[12];
    sOne.newy = mat[13];
    sOne.newz = mat[14];

gl.glPopMatrix();


same with object sTwo.

the newx, newy, newz should be the new pos of the objects. but it don't seem
to be.. I wont to do lines between the object so I do this after all is
drawn.


gl.glPushMatrix();
    gl.glLineWidth(2);
    gl.glBegin(GL_LINES);
        gl.glVertex3f(sOne.newx, sOne.newy, sOne.newz);
        gl.glVertex3f(sTwo.newx, sTwo.newy, sTwo.newz);
    gl.glEnd();
gl.glPopMatrix();
