Question

Can someone help me understand this topic in computergraphics course?

Z-Buffering and Raytracing both have fairly distinct uses. While the end result is a rendered image, the approaches taken to get there - and the techniques available - vary wildly with each algorithm, the following:

What are the differences between Z-Buffer and Raytraced rendering?

What are some common uses of Z-Buffering?

What are some common uses of Raytracing?

What is an example of a technique that is easy in Raytracing, but complicated in Z-Buffering?

THANK YOU

Explanation / Answer

1)
z-buffering is all about management of image depth coordinates. where as in ray tracing technique
itis all about tracing the path od light through pixels.
ray tracing technique has greate scene quality comparatively to z buffer.

----------------------------------------------------------------------------------------------
2)
z-buffer mostly used in computers epecially for computer gaming field. It was implemented as
hardware in silicon ICs. For creaitng movie effects also , z buffer used.

---------------------------------------------------------------------------------------------
3)
Ray tracing is used for realistic simulation of lighting. For movie effects such as shadows..
this technique is widely used.
------------------------------------------------------------------------------------
4)
Very familiar example is .. creatting shadow effects in easy in ray tracing ..where is difficult
in z-buffering.
