echinopsis posted:https://youtu.be/BpT6MkCeP7Y oh yeah i remember these the geometry is really nice on the closer street scenes. it has a real-esque look to it, but not anywhere near as smooth. way too noisy, especially when moving because the ray hasn’t caught up between frames, so it’s nothing that could be playable like something running with rtx

Good Sphere posted:oh yeah i remember these this is true but also a 4 year old video also the method it uses is that it blanks out whenever camera moves, and then sends samples. it could possibly use a method of using the previous frames rather than blank to start. would look a bit motion blurry but would look less noisy point also is that if they made a card that had dedicated solvers for path tracing, then wow. would be crazy insane good. the lighting is just so superior

but lol I also realise that gpu engineers aren't stupid and that my worthless opinion is based on lack of information and being a dork

heh well since exploring it im discovering real time path tracing engines inside unity 2018 etc anyway. this ray tracing poo poo is poo poo they integrated that brigade engine into octane which is a gpu render http://on-demand.gputechconf.com/gtc/2018/video/S8950/ this video is long and dumb but the quality is off the hook given the frame rate. gonna put this technology into games? gta 6 is going to be so beuaitful echinopsis fucked around with this message at 10:50 on Aug 24, 2018 |

yeah but the rtx is ray tracing, not path tracing, so it's always going to look like a game ray tracing sends a ray, and then when it hits that point, it tries to send rays to the lights, and if it gets there, it lights up the point, and the shading is determined by the normal to the light using like phong shaders or whatever path tracing sends a ray, and when hits a surface, bounces the ray according to the surface (ie, a mirror will be a straight bounce, but a diffuse surface will bounce the ray in a random direction (as in real life)), and then continues bouncing, picking up the colour changes, and when it hits a light, then it lights the surfaces. because the bounces in path tracing are random (as in real life), you need multple samples per pixel, whereas ray tracing only needs one. unless these guys mean path tracing when they say raytracing, I am just not happy with what they're doing looks like path tracing is coming to games. there are vids on youtube with quake 2 with path tracing.. but this isnt't that

https://www.youtube.com/watch?v=7MV26bOSAyk this is minecraft using pathtracing, or at least uses pathtracing for an aspect of the shading. it also uses temporal samples and I think traditional shading, and combines them or something so you dont get that noise effect but ya do get accurate lighting its good go to 5:13. it almost as if it uses pathtracing or something, but locks the samples to the surfaces that are seen.. its an unusual effect because when he goes around a corner, and sees a surface that isnt currently on the screen, it redraws it. looks like its fading in, in a unique way. ots gppd

sounds like you would need to trace a lot of rays to do this "path tracing"

mate yes the rodtronics poo poo I make like this : is like 2500 samples per pixel and its still a bit noisy to be fair that is completely true path tracing without any tricks. im sure real time stuff has all kinds of tricks to improve efficiency (like low res light samples and screen res texture samples, or something)

in a not unreal way, the noise resembles photos taking in low light with high iso film. as in the cause of the noise isn't dissimilar, high iso film is basically low # of samples with high brightness per sample

echinopsis posted:mate yes woah sweet. i have no idea how you’re getting that rainbow effect in the edges, but it’s awesome i’ve used mandelbulb, but for some reason in can only make the lighting convincingly realistic in black and white, though the color’s still cool this is sorta a doomy looking this with color
