Perspective Correction in 3D Rendering: Before and After Visual Comparison #1529663 (License: Personal Use)

Panel (a) displays a checkerboard floor rendered with strong perspective distortion, where tiles near the horizon appear compressed and skewed due to wide-angle projection. Panel (b) shows the same scene after applying perspective correction, restoring uniform tile proportions and enhancing spatial realism. This visual contrast is critical for calibrating rendering engines and evaluating camera models in computer graphics.

Used in technical documentation, computer vision tutorials, and 3D graphics software guides to demonstrate perspective warping and correction techniques; targets developers, researchers, and students seeking to understand projection geometry.
