> "maybe in a few years I can just raytrace" HOO WEEE BOY, God I know that one all too well. I did a similar thing. I was working in reinforcement learning and there were some key problems, so I thought "oh you know I'll go do some work in supervised learning, hopefully by then the problems are alleviated". So a year goes by and the field has improved somewhat, but now the mindset is shifted toward mega-compute. So I think to myself, "okay well ill go spend the time in pure mathematics, and hopefully by the time I get back things will be more stable ...".

Shadows are such a fun and frustrating topic. A few alternative/complimentary techniques to shadow maps are screen space shadows which can be combined with shadow maps to enhance small details and soft shadows using signed distance fields. SDF shadows are used by the unreal engine to shadow objects outside the shadow map range. An interesting enhancement for cascaded shadow maps is a tight fit to the depth buffer range. This can be achieved by creating hierarchical depth containing the depth min/max. The light matrices can then be calculated in a compute shader to keep everything on the GPU. I think the Order 1886 used this technique. Shadow map sampling also has a bit of varierty. Besides the traditional "blocky" PCF sampling a lot of people use per pixel rotated poisson disks. An alternative is to use a spiral pattern as those have less sample overlap when rotated. And of course going fully stochastic with a low sample count and cleaning up with TAA. Another interesting approach is using screen space directional occlusion to approximate short soft shadows. Although I believe this is mainly used to provide shadowing for lights that can't afford a shadow map. This was originally used in Cryengine 3 and more recently in the Demon's Souls Remake.

I would say best solution for implementing some algorithm would be to mostly use the paper, and use some "random" code from github for reference if/when you you get stuck from the pure paper (which will happen). Haven't done this a lot for 3D graphics algorithms (yet), but it was my goto when doing more advanced AI algorithms in uni.

About what you said in the beginning. I find working on code and pretty much any other creative work at the same time to be very hard. Let's say the brain is a workshop, once I've put out all the tools needed for coding, there's no space left for the tools needed by others type of jobs and I have to put all your code tools back in the cupboards before starting another job. Otherwise it's too messy to make sense of anything. But I know someone that doesn't seem to have this issue.

Hey, very cool video. I was just curious about something as I tried to implement PCSS a little while back, and I would have issues where if one object was directly in front of another (like a pole in front of a wider pole) with the light facing them dead-on, the blocker search would give a value closer to the front pole's depth when sampling for points that are behind them both, and the resulting shadow would have a high-penumbra streak in the shadow of the pole in the back. So essentially there would be like an inverted shadow of the front thin pole behind the back wide pole. Tweaks to the numbers for blocker search size and everything could fix for very specific cases, but never for general cases. Did you ever encounter this issue, and if so how did you work around it? Do the cascades fix this issue, as I did not get around to implementing those before dropping for variable penumbra for the time being, in favor of another solution (currently using prefiltered EVSM and it looks really nice, but that contact-hardening is still so nice).

For debugging things like cascades (and many other things in fact), you should have two types of cameras. 1) The game camera, that is what your rendering is based, all the frustrums, cascades, culling, LODs, etc. 2) Debug / editor camera, which allow you to actually move around, and see things from different viewpoints, without affecting any. If there are some shaders that take into account some view vectors, you might have additional option which camera to use.

Are you also going to implement shadow maps/baked lighting? I imagine that as long as one doesn't do something as silly as dynamic time of day, this could be a giant win in performance and visuals. It would probably need to be ray traced with something like Radeon Rays or something. I imagine Cinema 3D would be cost and license prohibitive.

@@ventusstrife6715 One use case that I use it for is scripting language binding. If you can bind member functions to a scripting language and create an API with that it'll drastically increase the flexibility of the engine. I did mine for Lua binding, and the method that I used was I defined functors to pull individual values off the stack, and called the member function with std::apply and an array of those functors. It's quite a bit more involved than member/data reflection, but it's well worth the investment.
