True.
At 1.3 seconds though I was assuming it was an older version that doesnt take advantage of modern hardware/software though.
For such a simple scene 1.3 seconds seems way too long.

Ray tracing can take as long as you want, depending on the quality you want to achieve.

Rather than use lightwave, I'd consider something like Andrew Kessler's Businesses Card Raytracer. A simple, one file tracer that is easy to compile and run. It's very branchy, arithmetically dense and even had some logic operations in the path tracing (the objects are positioned in a bitmap). It's not designed for speed, it was the smallest ray tracer that could be written. There are de golfed versions available and runs as a single thread.

@Karlos

Sure, hence the "for such a simple scene" (in Lightwave, as per the discussion).
It's not just cpu being used with modern hardware/software, it's gpu too.
Given the scene/textures/resolution/etc. it could be rendered (number pulled from a hat) hundreds of times a second in a modern version of Lightwave with modern hardware.

Having said that, Id hazard a guess the vast majority of the time @1.3 seconds is the initialization, not the rendering, so perhaps the single frame of the render was 1.3s on modern hardware/version of LW.

@fishy_fis

This is why AEK would make a good test. I had my own de-golfed version that could be used, maybe with a higher resolution and ray per pixel count.

1.3 sec on native Lightwave if I am correct.
No comparison.

Why?

Quote:
The 21 sec results in this topic for the 13900K are more usefull, comparing them with 68K emulation on Amiga platforms like Petunia, Trance and Emu64.

Well, I have given you mine 54s for 5800x, there's that

I can't get the render screen to play nice to render the scene via LW but using Shell via ScreamerNet to render as per walkero over at amigans instructions:

AmigaONE X1000, PPC, OS4.1FE- 17m10s

BUT this is not comparing apple to apples though as per the steps from post 1but still cool to try.

T do so make sure your using v5, open Shell and type:

xx:xx/Lwsn.fp -3 scenes/benchmark/Raytrace.lws 0 0 (x is location of your Lightwave folder)

( Emulation of ) Lightwave on Amiga vs native Lightwave on a Windows machine which can support every core, hardware support on the gfx chip.

@bennymee

That's how you get the ratio between emulation and native, ain't it not?

@pixie

The one called "raytrace.LWS".
I watched Youtube video at the start of this thread, downloaded the files and followed it to a tea.

I must admit Im surprised by how much faster this machine is than my old Ryzen 9 5900x with WinUAE cpu emulation. It's often ~2x faster, sometimes less, sometimes more.

:O It takes about 10x as much on my 5800x...
