Will work on that next then). It will be cool -- and worth the wait. Sorry if the project got on stall for some years. Life can be difficult some times and it was for me for all these years. Yet I put my heart into writing what's about 500.000 words now which is equivalent of roughly 8 books of 200 pages. All this for free since 2009). I understand your frustration, but hopefully with time and the community support (don't expect any of the corporations out there to help us in that process) we will get these topics covered. But as I am no millionaire, I can only work at the speed at which I can feed myself.
sounds good!, i do very much appreciate all that you have written so far. its just that texturing is the one thing i really do find difficult and its frustrating its not there :) -- thanks again for all your hard work.
In the real world light travels from the light source to the eye. But this lesson xplains that simulating this with a computer is not efficient. A more efficient technique is to follow the path of light but in reverse, starting from the eye and waking back to the lights making up the scene. Again read the lesson(s) it's all explained and that's why the lessons are there in the first place.
Hum to familiarize yourself with shaders/rendering techniques, do you see any other way but to build academic/collegiate level knowledge on computer graphics? Would love to understand how you intent to achieve results without knowledge.
That's why the lessons are online. You can read through them and everything is explained there. In ray-tracing light most often travels from the eyes to the surface and from the surface to the lights (direct illumination). Various laws (such as as the inverse square and lambert-cosine laws) are applied to simulate reality.
Just remove the images now, until you have real ones.
I've seen several blogs/sites of decent quality and technical depth start throwing random semi-related generated images into their articles, and it just makes me immediately wary of BS. No images is better than AI-generated ones if you want your site to look like it was made with care and has good information on it.
