Preparing for “Fundamentals of Rendering”

Hi,

I am planning to post some write-up on Fundamentals of Rendering soon. I am now preparing for some good topics on that. I am getting this ready, by using my collection of articles, notes, tutorials and by my personal experience of last 8 years in CG field.

The points will cover fundamentals of digital rendering in 3d softwares, such as Render Engines, Rasterisation, Resolution, Anti-aliasing, Aspect ratio, Ray-tracing, Render passes, Effects like DOF, Blur, Indirect Illumination, and so on…

If you have some more points regarding rendering, please list them below in the reply area. We all will discuss them together.

Stay tuned! See ya soon!!
