Ayou can easily "recurse" them, plus the resolution doesn't decrease when you get closer, and there's no additional memory needed for the potentially 4 or 5 render targets if you are using deferred rendering
Ayeah lol
Ehello again 
back from school.. thinking about OpenGL and Silk.NET
yesterday i started working on adding textures to objects

Twdym? when a ray hits a portal you can just move it over, that's why it's trivial
Ryepp, and the reason it does not recurse is because there is a limit to how many times the ray can be: reflected, refracted and moved/teleported
Ato me, this looks like it is quite obviously just a render target
Tthey could show it off better if they got more light through the portal
Aif they can prove it is raytracing then i would love to see that. although i don't really know what the point would be considering that you can do the same with a render target or stencil buffer
Abut i'd be happy to see me proven wrong
Tit would just be a lot more unnecessary work to add render targets when dealing with rays already
Ai suppose if the entire scene is raytraced then yeah
Ti guess a good showcase would be putting an object in the middle of the portal
Ayeah
Tyou would not need to render objects twice like with render targets, it should "just work"
Talthough not really because it would be in two locations at once...
Traster enjoyer yells at rays

QI mean you could do this recursively with N render targets and then put them into each-other. Wouldn't that allow portal recursion (You set a recursion-max yes, but you also set a ray-bounce-max and there's no point in going beyond a certain depth)
Ayou can, that would be potentially a lot of memory though
Qyou really don't need a high resolution after the first idk. 3 cycles
Athe best way to render portals (in my own opinion) is absolutely the stencil way though. no additional render targets, just additional draw calls
QI don't know if it's the best - but I like the stencil buffer so yes
Aportal uses it, imo that's about all the endorsement it needs lol
SMeta AI
Bringing open intelligence to all, our latest models expand context length, add support across eight languages, and include Meta Llama 3.1 405B— the first frontier-level open source AI model.
Tshould get one of those GPUs with an nvme slot and use flash as memory :zigfast:
SI'm testing the 8B now and it's pretty awful, hard to say if its the model being bad or the software is broken currently
RUgh. still cannot get imgui to work properly
Rlooks like font issue? changing font configuration breaks it even more (nothing drawn)
Rsizing of the panel is also odd compared to its content...
Rat a loss on how to debug this too 
Pthat's very strange
Rhm these are my UVs though....
R
Rthis is in.color (without applying texture color). I dont know what it is supposed to look like, but it looks weird to me too
RQuite unlikely the UVs are always 1...
Sits 6am and i still cant sleep
Si give up
TEyy
TSame boat

CXima is a nice guy, just ask him. He is in a mutual server with both of us.
Lthe point is that their engine is already ray-traced, so portals are easy
why do it with a render target when you can just
move the ray

APerhaps my definition of what ray tracing on modern hardware is wrong, I did not think that entire scenes could be ray traced in real time, this just looks like rasterization to me. I do have a bias against "ray tracing" due to Nvidias crappy hardware ray tracing, it just looks like a gimmick that reduces FPS and encourages the use of crap like DLSS. Granted I have not looked in years because I don't care about GPUs much
AIf this entire scene is actually ray traced then that is legitimately cool
LGPUs can do real time path/ray tracing yeah
Lits been possible for many years
Lits just that the quality of the ray tracing is much better nowadays
Lyou can get very very high quality ray tracing nowadays in realtime
Lyou could do realtime ray tracing on the GPU in the past, but it wouldnt look better than rasterization due to perfomance issues
