Ray tracing and Z buffering in graphics - Stack Exchange
https://gamedev.stackexchange.com/questions/146378/ray-tracing-and-z-buffering-in-graphics
For your second question, recent progress in graphics, particularly with deferred rendering, has enabled graphics developers the ability to use some ray tracing techniques in a Z-buffered system for effects like screen-space reflection and shadowing. These are often used with deferred rendering, rather than forward rendering, as shader writers ...

The pioneering research of Chen and Liu [10] in the hybrid rendering has suggested the use of the z-buffer map source as an approximation of the primary rays to accelerate the ray tracing. ...
The Ray-z- Buffer - An Approach for Ray Tracing Arbitrarily Large Scenes
https://www.researchgate.net/publication/2644325_The_Ray-z-_Buffer_-_An_Approach_for_Ray_Tracing_Arbitrarily_Large_Scenes
The ray-z-buffer algorithm presented here is part of an alternative strategy of ray tracing called breadth first ray tracing. Breadth first ray tracing differs from usual pixelwise rendering in ...

Effects that are difficult with Z-buffer, are easy with ray tracing: shadows, reflections, transparency, procedural textures and objects. Assume image plane is placed in the virtual space (e.g. front plane of the viewing frustum). Algorithm: for each pixel shoot a ray r from the camera to the pixelshoot a ray r from the camera to the pixel

Area Sampling Buffer: Tracing Rays with Z‐Buffer Hardware
https://onlinelibrary.wiley.com/doi/10.1111/1467-8659.1130299
An algorithm that allows the use of z‐buffer hardware in assisting area sampling for a ray tracing style renderer is described. The implementation issues involved in discretizing the sampling area and light source area are discussed and solutions are proposed.
Z-Buffer - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/mathematics/z-buffer
A ray tracer gives access to certain realistic effects not readily available in a hardware Z-buffer renderer, e.g., shadows, atmospheric effects, and procedural textures (Musgrave, 1990, 1991). A result of this effort is seen in Plate 1 (see color insert), a panoramic view of …
Hierarchical Z-Buffer Visibility - Princeton University
https://www.cs.princeton.edu/courses/archive/spr01/cs598b/papers/greene93.pdf
tions are Z-buffer scan conversion and ray-tracing. Since Z buffers do not handle partially transparent surfaces well, we will restrict the discussion to models consisting entirely of opaque surfaces. For these models, only rays from the eye to the first surface are relevant for visibility, so the choice is between Z buffering and ray-casting ...
