Visualizing Perspective Transformation to NDC
Perspective projection is a fundamental concept in 3D graphics. This transformation, akin to morphing a view frustum shape into a cube—known as Normalized Device Coordinates (NDC)—, generates a realistic foreshortening effect when applied to all scene vertices. The visualization below showcases this transformation on a set of cajas, rendered with a custom shader for shape morphing and viewed from a third-person perspective using a secondary camera, which enables the display of the main view frustum....
