imgtrans is a Python library developed by Ryu Furusawa. It works by stacking consecutive video frames along the depth axis to form a volume with three axes: X, Y, and T (time). Within this video volume, the user can cut slices from arbitrary angles, allowing the extraction of cross-sections that reveal distorted temporal structures not visible in ordinary playback. In the provided context, the method is described as a computational extension of slit-scan principles and as a sculptural process that treats moving images as a plastic mass containing color information. It is also linked to a transformation from perspective space converging toward a vanishing point to parallel projection without a vanishing point.
