3D rendering using GPU cores

What would be a wonderful solution for the rather extreme slow rendering of 3D images. Especially the very long rendering time when images are needed in higher resolutions i.e. 4000 pixel.
A 3D rendering engine that uses all the GPU cores of a modern video card i.e. Nvidia.
That would be awesome!

Something like the Cycles renderer as used by Blender, Poser, Rhino. Open Source so well suited for Sweet Home 3D.
I have a brand new RTX4070 waiting in the box for my new machine to get back from repairs. That would make it fly [:)]

This has just released, I think it could be of help since makes Java apps to run on GPUs, FPGAs and more.

The render engines used in SH3D aren't written in java, they are external native code called using JNI.

By the way I'm working on a solution to unload our CPUs while rendering, I will provide more details in the next weeks. Stay tuned!

Sorry, but SunFlow is written in Java.

@Puybaret
Thanks for having pointed it out, I wrongly assumed that it uses a DLL like Yafaray does.

About porting java code under TornadoVM, I ask myself how much easy could it be. From a first look it seems that it's easy to port pieces of code that already looks like code that should run on a GPU (such as kernel operations), so I wonder how much of SunFlow is affine to this porting, considering that it has been designed to run on a CPU and may have just few routines that match the requirement.

A relatively easy improvement could be to not change SunFlow at all, but to implement an additional denoising step that would allow to have smooth images without having to render at larger resolution than required just to shrink them back to destroy the scratches. This could be applied after the rendering made with any engine, so the denoising code can be shared for both SunFlow and YafaRay. However, to reach the state of art in denoising algorithms, the render engine should be modified to output not just the pixel colors, but also the normal vectors of the rendered surfaces.

By the way I also wonder if anyone is going to try this integration.

I'm reading with bated breath. Dear gurus. Please do something else for all of us. I will make a wish for the New Year so that the rendering will be faster). And we really need a fast YafaRay.

Hi, any news about that?

[Puybaret]

Don't believe too much in Santa Claus.
If it was simple, it would have been avalaible for a long time.

I can give a little anticipation: the solution I'm working on will be cloud based, that means that you won't need to buy costly hardware to speed up your renderings. But, even more worthly, you can continue working on your home, or just power off your PC while the rendering is executed in the cloud. And, moreover, you will be able to render files made with SweetHome 3D Online, without the need to install the program on your PC.
