if 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

AquaOP•7/23/24, 4:31 PM

but i'd be happy to see me proven wrong

TechPizza•7/23/24, 4:32 PM

it would just be a lot more unnecessary work to add render targets when dealing with rays already

AquaOP•7/23/24, 4:32 PM

i suppose if the entire scene is raytraced then yeah

TechPizza•7/23/24, 4:32 PM

i guess a good showcase would be putting an object in the middle of the portal

AquaOP•7/23/24, 4:33 PM

yeah

TechPizza•7/23/24, 4:33 PM

you would not need to render objects twice like with render targets, it should "just work"

TechPizza•7/23/24, 4:33 PM

although not really because it would be in two locations at once...

TechPizza•7/23/24, 4:34 PM

raster enjoyer yells at rays

I 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)

AquaOP•7/23/24, 4:35 PM

you can, that would be potentially a lot of memory though

queenvicky•7/23/24, 4:36 PM

you really don't need a high resolution after the first idk. 3 cycles

AquaOP•7/23/24, 4:36 PM

the best way to render portals (in my own opinion) is absolutely the stencil way though. no additional render targets, just additional draw calls

queenvicky•7/23/24, 4:37 PM

I don't know if it's the best - but I like the stencil buffer so yes

AquaOP•7/23/24, 4:37 PM

portal uses it, imo that's about all the endorsement it needs lol

should get one of those GPUs with an nvme slot and use flash as memory :zigfast:

sowa705•7/23/24, 5:29 PM

I'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

Rahkiin•7/23/24, 6:49 PM

Ugh. still cannot get imgui to work properly

Rahkiin•7/23/24, 6:49 PM

looks like font issue? changing font configuration breaks it even more (nothing drawn)

Rahkiin•7/23/24, 6:49 PM

sizing of the panel is also odd compared to its content...

Rahkiin•7/23/24, 6:50 PM

at a loss on how to debug this too

Perksey•7/23/24, 7:00 PM

that's very strange

Rahkiin•7/23/24, 7:04 PM

hm these are my UVs though....

Rahkiin•7/23/24, 7:04 PM

Rahkiin•7/23/24, 7:06 PM

this is in.color (without applying texture color). I dont know what it is supposed to look like, but it looks weird to me too

Rahkiin•7/23/24, 7:27 PM

Quite unlikely the UVs are always 1...

Xima is a nice guy, just ask him. He is in a mutual server with both of us.

AAqua if they can prove it is raytracing then i would love to see that. although i don...

Lyris the Kitori•7/24/24, 9:51 AM

the 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

AquaOP•7/24/24, 10:20 AM

Perhaps 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

AquaOP•7/24/24, 10:20 AM

If this entire scene is actually ray traced then that is legitimately cool

Lyris the Kitori•7/24/24, 10:21 AM

GPUs can do real time path/ray tracing yeah

Lyris the Kitori•7/24/24, 10:21 AM

its been possible for many years

Lyris the Kitori•7/24/24, 10:22 AM

its just that the quality of the ray tracing is much better nowadays

Lyris the Kitori•7/24/24, 10:22 AM

you can get very very high quality ray tracing nowadays in realtime

Lyris the Kitori•7/24/24, 10:22 AM

you could do realtime ray tracing on the GPU in the past, but it wouldnt look better than rasterization due to perfomance issues

AquaOP•7/24/24, 10:22 AM

I see, neato

TechPizza•7/24/24, 10:23 AM

voxels are also faster to trace than typical geometry

Lyris the Kitori•7/24/24, 10:23 AM

No! Euclid! is a good example of fairly early real-time GPU ray tracing

Lyris the Kitori•7/24/24, 10:23 AM

that engine can do real time ray tracing on a GTX 540M

Lyris the Kitori•7/24/24, 10:23 AM

its just
Not Pretty

AquaOP•7/24/24, 10:26 AM

Seems like I need to look into what a modern GPU can actually achieve

AquaOP•7/24/24, 10:27 AM

I guess this is what ignorance, a gtx 1060, intel igpu as a primary GPU, and star citizen running at 5 fps on a 6750xt does to you lmfao

sowa705•7/24/24, 10:38 AM

I mean you can literally play cyberpunk with full path tracing

if they can prove it is raytracing then i would love to see that. although i don't really know what
