I keep on watching the speed at which real time GPU ray tracing / light
transport technology advances.
It seems quite amazing.

So, let's say hypothetically at what version POV-ray would have to fork so that
its SDL is entirely covered by NVIDIA Vulkan Ray Tracing API as of today ?

I am currently reading that tutorial

the tutorial specifies : plain colors, textures, diffuse and specular
reflections, lighting. no transparency for now.
Seems we are in povray 1.0 territory.

I will browse the reference to see if there are now more documented features
since the tutorial webpage date is May 2020)

The goal being to make both rendering pipelines meet where the least of code is
required for the glue.

I think i will try a hello world by converting biscuit.pov into Vulkan TLAS/BLAS
and trying a render.

To be honest, I think it is a matter of a couple of years that fast GPU assisted
ray traced
render is achieved at the levels of POV Ray 3.6, since in December 2020 Nvidia
was already implementing caustics (using POV-Ray as a reference on the matter by
the way)


let's be clear rendering time is the top factor in the game now. Always has

As a reference and a dean in the game of RAY tracing, I think that porting
POV-Ray SDL to the recent hardware advancement is fair game, could be done as a
tribute, that NVIDIA could even handle in part, but that's more of a political
issue, and it's just an humble advice, since the workload could be quite big.

It is probable the that NVIDIA engineers browse POV-Ray codebase.
Maybe there is a possibility to make the Vulkan ray tracing capabilities grow in
tandem with  those of povray. so that porting would be easier.

If there is one thing that would be an absolute hit, it is a povray 4.0 renderer
that renders in an instant, even if some SDL directives have to be ignored for
that at the moment.

What do you think ?
