Moving the camera -> the bsp world is shaking

[Soldier of infortune]

Hello

When i move the camera the bsp world is shaking. Have you got an explication for this strange effect ?

This is my code :

Code: Select all

		core::vector3df cam_pos = camera->getPosition();
		core::vector3df cam_tar_pos = camera->getTarget();

		cam_pos.X -= 1.0f ;
		cam_pos.Z -= 1.0f;	

		cam_tar_pos.X =  1.0f ;
		cam_tar_pos.Z =  1.0f;

		camera->setPosition(cam_pos);
		camera->setTarget(cam_tar_pos);

Thanks.
