Silhouette Parallax Occlusion Mapping in Modern Video Games: From Height-Field Ray Marching to Carved Real-Time Relief

Parallax occlusion mapping (POM) is the standard way modern games add centimetre-scale relief to surfaces without the memory and vertex cost of tessellated geometry. Yet classical POM only shifts texture coordinates inside a mesh whose outline, depth and shadows remain flat, and...
