Projective transformations

Projective transformations are mathematical techniques used to change the perspective of an image or shape, simulating how objects appear when viewed from different angles or positions. They preserve straight lines but can distort sizes and proportions, allowing us to "reframe" or "warp" images to correct perspective or create artistic effects. These transformations are widely used in computer graphics, image editing, and photography to produce realistic representations of scenes from different viewpoints, making two-dimensional images more closely resemble how our eyes perceive three-dimensional space.
