@MomentsInGraphics @c0de517e Sad ! being caught in work I dont think I will be able to finish paper I wanted to submit to HPG :( seems I have to go for JCGT. Working full time in non research team and find time to publish is sooooo hard :(. Though looking forward to all cool work and all the best with conference!
@neilhenning @aras @wolfpld I can empathize with you. You have spent 20+ years and have seen Unity grow from infancy. I hope you will be able to detach yourself and move on. I come from country where we have sunlight 12 hours a day 365 days. So coming to Canada hits me really bad. What I found useful is going out right as I wake up. Doesnt matter what I do most of the time I just take coffee and sit. Second is having a hobby for me music helps. So I keep learning musical instruments. Take Care!
@yiningkarlli I am really happy and humbled that you noticed my work :). Thanks alot for your kind words, means a lot coming from you!
@yiningkarlli your hobby project Takua renderer and your website was the reason I got interested in path tracing :) . I still cant forget the beautiful renders on that website. I still remember I showed it to my friend and we both said its surely not possible to the point we thought its fake :)
@dbat thanks a lot for suggestion. I will try to do that😊
Here I cover basics of how light modeled i.e light as particles travelling in straight line, assumptions with geometric optics, cosine law, intuitive derivation to rendering equation as integral over solid angle.
I am a self taught graphics programmer. I learnt path tracing/re learnt it and iterated it over and over many times. I had many gaps in my knowledge. I went back and back till time I find my self in position where I can teach someone. I meant to write blog posts someday but with my current workload it seems it will take time so I am sharing poor mans notes here and hoping someone will find it useful. I will release them in parts.
Here is the implementation for Single pass LBVH based on the paper "Fast and Simple Agglomerative
LBVH Construction" : https://github.com/Niravaana/HIP-BVH-Construction/blob/main/src/SinglePassLbvh.cpp
You can also find two traversal methods there if/if and while/while based method as discussed in research paper "Understanding the Efficiency of Ray Traversal on GPUs". More methods from this paper will be added along the way.

This is reference implementation for research paper ero Karras, "Maximizing Parallelism in the Construction of BVHs, Octrees, and k-d Trees", High Performance Graphics (2012) - Niravaana/...
