The holoprinter technology based on holographic stereograms has generated a fast development in holographic display applications by the holographic recording of a 2D image sequence with information of a 3D scene, which could be real or computer generated. The images used in holographic stereograms initially start from the acquisition of the different image perspectives of the 3D scene by the re -centering camera configuration and then, this images must be rearranged before the optical recording. This paper proposes a method to acquire the required images or hogel images in one step without using rearrange algorithms, the method uses a virtual camera that moves along a virtual rail by conventional computer graphic s software. The proposed method reduced the time required to ob tain the hogel images and enhance the quality of the 3D holographic images; it also can be applied in different computer graphic s software. To validate the method, a full parallax holographic stereogram was made for a computer generated object. Key words: Holographic displays, Holographic stereograms, Holoprinter, Hogel images .
