Oh, maybe I get it. I need to send plane to GPU with the same size like the screen size. First problem was frustum culling, because coordinates are in another coordinate system, I didn't realize, that will be discard (and probably if is camera position in 0 and object position in 0, will be also discard). And probably second problem is in building object and merge the vertices? Could you confirm it? If yes, how can I fix it?
plane.addTriangle(new SimpleVector(-1, -1, -1), 0, 1, new SimpleVector(-1, 1, 1), 1, 0, new SimpleVector(-1, -1, 1), 0, 0);
plane.addTriangle(new SimpleVector(-1, -1, -1), 0, 1, new SimpleVector(-1, 1, -1), 1, 1, new SimpleVector(-1, -1, 1), 1, 0);
plane.translate(1, 0, 1);
worldDOF.getCamera().lookAt(new SimpleVector(-1,0,0));
