@SignataDesign
All i notice is that path tracing is just brighter 😂
Infact, They are technically the same thing, but the implementation is different. So-called ray tracing effects are added to a rasterized scene, and effects can be divided into ray-traced reflections, ray-traced GI, etc. So you can disable less important effects and have better performance. The path tracing method constructs the whole frame using rays with all effects on with adding color estimation. No rasterization and more expensive. Direct and indirect lighting quality depends on bounce count, not the implementation. You will still have less correct indirect lighting with path tracing if you limit bounces to fewer counts.
Yess i agree both are technically same, but they have difference style to handle the inderict lighting. If you know about cook stochastic theory in 1984 about distibution theory in Ray tracing, that was the basic of Ray tracing now. And path tracing is based on Kajiya-style diffuse interreflection by James Kajiya 2 years after cook stochastic. If you read that theory, then you will know both are basically same but different in style 😊😊😊
@@SignataDesign I didn't read about them. Thank you, I will check them out. I agree they have differences in application yet if they are done correct they should output similar and natural results assuming they are using correct PBR maps. Anyway, I will check them out and come back 🤘🤘
@@user-dp8ez9ik9e i really like this kind of discussion😊😊. Please comeback and disscuss again
@@SignataDesignnot really different either, one is just new to common parlance to differentiate itself from more raster dependent solutions. The debate between bundling, descret, and more complete systems have been a debate in ray tracers forever.
@@SignataDesignmaybe I'm wrong, but the method of scattering is controlled by the BSDF (bidirectional scattering distribution function) or BRDF.
Tho I've never heard one referred to as path tracing and one as ray tracing.
The difference is this:
Path tracing bounces on 100% every geometry objectin your scene.
Imagine foliage, water, leaves on a tree, everything.
You can imagine that in realtime this would destroy your framerate.
This is why path tracing is an offline, post processing intensive gpu task. It works on a single frame at a time. Therefore, single shot renders or movie renders are perfect for path tracing.
Ray tracing is for high fps realtime gaming and therefore less realistic and less performance intensive.
Path tracing appears to produce the majority of the best results in these examples although lower-tier GPUs will struggle with it. In the Cyberpunk 2077 examples, for instance, it looks like I would have to employ DLSS upscaling to make up for the performance loss. A great-looking game that runs poorly isn't fun, in my opinion.
I have a 4090, and I9-14900k, running pathtracing with the game maxed out and dlss enabled I get about 70 - 80fps, its perfectly playable but the fact you need a 650 dollar cpu and a 2000 dollar gpu to even get a playable framerate and STILL need DLSS is insane, though I think its insane even base ray-tracing can even be live rendered in any regard.
very good comparison. brilliantly done.
thank you so much
@@SignataDesignyes really keep it doing. Try using better voice ai or your own
Using path tracing reduces shadow load and introduces unnecessary light.
Good movie
RAY TRACING... let's add more details to the dark and light bits... like better contrast kinda thing
PATH tracing - add MORE light to everything everywhere and reflect everything everywhere
Does nvidia 1650 and 16 gb ram .can handle both ray tracing and path tracing?
I already try it, you can still use path tracing but it only can handle low path tracing in twinmotion
Yes u can easily get nearly 420fps in 4k
Very good !!
Thank you😊😊😊
Buen video y explicación. Estaría bueno que, si agarrás fragmentos de videos de otras personas, lo menciones en alguna parte. Por ejemplo, los de cyberpunk. Sorry but i dont know much english
Oh like the source or courtesy. Sorry i forgot to put that in the video. Actually i already done that in previous video but i forget in this video😊😊
this feels entirely ai generated lol
@@breadone_ ?
Ray tracing is a cheap trick to try and do what they cant do but all gtx cards did full realtime path tracing no studio or 3d designer would use raytracing because its not in real-time its created on another process then put together with the lagg , path tracing is how we always did it in real time in the game hence why only creator pcs nobody wants rt cards above the 20 series for gaming or comples compute now they need to use ai on low ecor worse tech in 20 years we havent advance we went backward since 2080ti. people dont look at what lane speed or why 16 is the magic number in sending data 8 n 8 all at once hence 2 sticks ddr4 16 n 16 any more is slower any more cores is bad unless you multi task running many programs that create lag when the come together and bottlenecks, hence why ram ISNT COMPARABLE ON A CARD THATS USING 22 GB if its inp n out it to 10 CCORES its like a 1.2gb gfx card yet they say need more vram and blame devs when the games run perfect on gtx cards with only 4gb vram even doing 4k native smooth, because monolithic better cpus and gaming boards VS A MONO HAVING 11GB TO IT AT ONCE 64BIT VS X64 X86 XX86 OR XX64 READ ABOUT THE TRICKERY TO FOOL YOU WHY AMD ARE NOT THE SAME AS INTEL IN THE FLAGSHIP DAYS WHY THE SOCKET SUDDENLY GORT DOUBLE THE LEGS THATS NOT GOOD ITS MORE CHIPS MORE LATENCY 2 PROCSSORS LYING TO SOUND BIGGER N FASTER THAN 1 FAST PROCESSOR, YOU CANT HAVE LOW POWER AND BE ABLE TO BEAT THE HIGH END COMPUTE CPUS AND GPUS SOMETHING GIVES N THATS QUALITY, SND N GFX, RESOLUTION SCALING CANT DO NATIVE RAYS IT HAS TO RENDER THE IMAGE ON MEMORY INSTAED OF IN REAL TIME IN THE PROCESSOR. GAMERS DONT WANT CREATOR PC SOLD TODAY WITH GAMING PC LABEL ON IT, THEY AINT ANYGOOD.
ray tracing looks better in all the environments except for 6:50 when its looking outside from indoors, path tracing was the superior one there.
That's why path tracing need higher specs😅😅
Rt is better for animations it’s seems.. but the other aspects of 3d work will also make break throughs.. such as Models and textures..
RT OFF is better
I found the same 🙂 btw can someone explain what does that RT off work in comparison to rt and pt on like this video
@@sibaprasadlenka1259 the technique with RT off is called Rasterization and is the standard for most video games since it is quite performant. Here each object is lighted separately without taking other objects into account. As a result the lighting is unrealistic, but can be faked by various methods to look good. Which is probably why you prefer its style.
Ray Tracing is a gimmick to sell games and graphics cards at sky high price
It's not a gimmick, if you cared about playing the game with beautiful graphics you would understand why ray tracing is important
@@Kitzoa7 without any water or glass surface in the environment 90% of time no one can tell the difference whether RT is on or off. It's a f*ing gimmick.
