  We introduce altiro3D, a free extended library developed to represent reality
starting from a given original RGB image or flat video. It allows to generate a
light-field (or Native) image or video and get a realistic 3D experience. To
synthesize N-number of virtual images and add them sequentially into a Quilt
collage, we apply MiDaS models for the monocular depth estimation, simple
OpenCV and Telea inpainting techniques to map all pixels, and implement a
'Fast' algorithm to handle 3D projection camera and scene transformations along
N-viewpoints. We use the degree of depth to move proportionally the pixels,
assuming the original image to be at the center of all the viewpoints. altiro3D
can also be used with DIBR algorithm to compute intermediate snapshots from a
equivalent 'Real (slower)' camera with N-geometric viewpoints, which requires
to calibrate a priori several intrinsic and extrinsic camera parameters. We
adopt a pixel- and device-based Lookup Table to optimize computing time. The
multiple viewpoints and video generated from a single image or frame can be
displayed in a free-view LCD display.
