Ren said texture mapping can be used to correct distortion, like the curved appearance of masks on a ship due to a curved lens in a photograph. My understanding is that here, the distorted image itself acts as the texture. Then, instead of mapping a simple rectangle on the screen, we map a "bent grid" onto the distorted image. This means each square of the grid gets mapped to a specific, distorted area of the image. By applying the distorted image (texture) with the "bent grid" mapping, we essentially corrects the distortion. It's like the bends cancel

Many image editing software packages feature automated lens distortion correction tools that can detect and correct distortions based on metadata embedded in the image file which streamlines the process for photographers
