I don't think that's Amiga related.

I Know that reading is hard but this is on General technology. And it's description says "This is the place to discuss about computers and technology in general."

@Rose

Really?

@Rose

Preciselly. Thank you.


@DiscreetFX

These days many amiga users have been talking about a new Quake 2 port, so I thought it would be good to bring this news here, to compare, because if many wrong things didn't happen, we would be leading this graphic revolution, I even remember a demo (sadly don't remember the name) which showed a realtime raytracer. But as we are now, well, it is sad, very very sad.

Neat video. I wonder how the nvidia RTX compares to the AMD Polaris that will be supported in AOS 4. I'm rusty on graphics cards, so I'll have to research it.

I mean the real question is "Can Amiga OS4 reach a more realistic 3D rendering GPU based"

IMHO for the moment NO

The demo said that it path tracing** and ray tracing

I am certainly the only one that have tried to port a simple raymarching* program to GLSL Nova : I must admit it was buggy certainly due to our GLSL implementation not mature enough.
(signaled to Hans but I didnt do a bug report as I dont have access to Mantis... also I dont have the latest Nova )

So I only can draw 2 raymarched spheres on a background with GLSL/GPU
Each time i tried to do a more complex scene bugs appears with no reasons
Was so disappointing

Note:
* raymarching is not the classic raytracing but an other GPU technique that compute procedural 3d objects based on their distance to a current xyz point

** path tracing is just an other algorithm that is implemented upside the raymarching or raytracing or raycasting routines to manage how the light ray reflect. I mean once you have a routines that return the normal & the color/material at a given xyz point then you can build a path tracing routine

Certainly the quake implementation use better techniques/GPU not accessible to our Amigas

@thellier

Well, get Mantis account :) It takes a couple of minutes and then you can start tracking bugs.

Beautiful is NOT the word I would use here, not just for Quake but for every 3D FPS game the industry has forced on us. Jerky ? Probably. No matter how many CPU/GPU cores and GHz, to me they all look like the terrible 3D attempts (for all platforms) of the 90s, the Tomb Raiders, the Monkey Island 4, the Dooms/Quakes/Glooms/whatever, the fake Mickey Mouse in crappy 3D cartoons our kids have grown up with. And that's coming from someone that has enjoyed quite a few of 3D games/demos (ugly or not, pseudo or real). I liked Unreal Tournament, played Quake, loved PacMania, just not as much as good old 2D games. Give me Pong any day.

@Rose - Thanks for your acknowledgment! Indeed, discussions about new Quake 2 ports have been prevalent among Amiga users lately. It's great to see the community engaging with these topics and comparing them. Although it is disappointing that we haven't led as much of a graphic revolution in this area due to past missteps, your mention of an early ray tracing demo highlights how far technology has come since then!

@DiscreetFX - Your lament over the missed potential for leading graphics innovation within Amiga circles is understandable. The reference to that groundbreaking yet forgotten demonstration serves as a reminder of what could have been if those earlier mis
