Our latest beta versions (4.5.1) adds the GPU acceleration for 3D VR mode.

https://www.radiantviewer.com/beta/

Volume rendering is started in the GPU mode by default (if a supported graphic card is detected).
Press F9 to switch between GPU and CPU modes.

can`t use GPU rendering in my notebook, only CPU, NVIDIA GTX970M, F9 does not switch

Please, add this feature for AMD Vega64 gpu?

@Luiz

Make sure that you have the latest GeForce drivers installed: https://www.geforce.com/drivers

@Carlo

We will explore the possibility of supporting AMD GPUs in the future.

Any chance to see improvements in Intel HD graphics?

So many of us work with ultrabooks with build-in graphic accelelators - please do consider it in your plans.

I have a Win7 x64 computer with an NVIDIA QUADRO FX 3700 card.

I don't see it on the list... does this mean that it's not supported?

@Marcel & @tomb745

Current Intel HD graphics are not very well suited for Volume Rendering. They substantially lack power required for computational efforts in VR. Creating VR images is very different from rendering game scenes.

@Tommy

Quadro FX 3700 supports the 1.1 version of Compute Capability.
RadiAnt requires at least CC version 3.0 (the most recent is 7.0).
You basically need the Nvidia graphics card released within last 5 years. Yours is 10 years old.

Ok, I understand.

1050Ti with latest drivers (390.65). Radiant does not switch to gpu rendering. Drivers and programm also reinstalled.

- I want to see the DICOM Header and search in it

Kiril, please try our latest beta (4.5.5). It seems that there was a library missing in the 4.5.3 setup file.

Stefan, just press CTRL+ALT+T when viewing a DICOM file.

Dear Radiant

Just need your advice for select Graphic card : GeForce GTX or quadro is better one for VR.
Some guy told me that GTX for gaming, not rendering .
is that true ?

Thank you

You'll be better off with a fast GTX card (1080ti or Titan). GPU acceleration was designed with the consumer cards in mind.

To all having issues switching to GPU mode on laptops, you need to add radiant to your nvidia control panel program options and set to always use nvidia for this program.

@Radiant team

I don't know if I've missed it, but is there an option to save the 3d reconstruction to a mesh or cad?

Thanks

@crow

No, currently there is no such option (3D export) in RadiAnt.
Thank you for your tip about GPU on laptops.

Tried latest version of Radiant using a GeForce GT 730 card. The 3D or MPR simply would not use the GPU. In fact, when I click the settings button I see two options: CPU and the GT 730 but the CPU seems to be always selected.
Checked out card drivers and everything seems to be OK.
Any idea on how to force Radiant to use the GPU?

Thanks!

@vaderbsb

It could be insufficient memory - if the volume data cannot be loaded into GPU RAM, the GPU mode cannot be enabled. We will probably add some error notifications for GPU mode.

@RadiAnt

After some update my tip doesn't even work for me anymore. I have dual cards an intel and other nvidia on my laptop. I had to go to BIOS and disable intels integrated. After that i was able to use nvidia for 3d rendering.

JJ here again, going to be a rant session. sorry.

Radiant,

Please take note of how many people here have questions related to laptop related hardware. Many of the people/radiologist using your product are doing so on laptops. they're taking their laptops to conferences and lectures...

With that in mind again I stress the importance of a local library. The people using your product are not using this for advanced post-processing. while generating cool 3d recons is neat and people like doing it quickly on their laptop. I'd recommend that the local library really take a preceding priority so you can gain wider market appeal.

Still a great product.
JJ

@JJ

No worries, it's going to happen ;-)

Incredible news guys! I'll be eagerly awaiting this feature. I'd expect to become the defacto dicom viewer for the non-Mac OS platform. Get your servers ready!

Indeed the local database will be a fantastic plus for this software. Just one note for the developers: please make sure that the user can choose the folder and specially the drive where the database is located. This critical for notebook users with a small boot SSD and a larger spinning HD. If only the C: drive is available for the database then we will be extremely limited!!

Surely, the database folder will be configurable.

I bought a new pc to work with radiant -ryzen 2600x, 16gb ddr4, radeon rx 570 4gb, but only afterwards I discovered that the 3d GPU render mode only works with nvidia cards... It is really a shame.
Any plans to make it work with AMD GPUs?

Sorry, no imminent plans for AMD GPUs... GPU acceleration is based on CUDA, which is available only for NVIDIA cards.

I wanted to report, I have GTX 1060 with latest drivers in latest radiant version and only shows CPU acceleration.

sorry my bad, wasnt on the latest drivers. It works great.

Glad to hear that, G-DAWG :-)

Any plans to work with AMD GPUs?

Sorry to disappoint you but not in the nearest future...

GPU function does not work on my computer with quadro k600 with latest drivers , in normal mpr it is possible which doesn’t seem to show any significant improvement from cpu but in vrt mode.... it just doesn’t run and switches to cpu all the time

@DD - your GPU is simply slower in this scenario then your CPU.

Quadro K600 has only 1GB of RAM. This might be not enough to load 3D volumes.

Any chance of supporting the new Intel Iris Xe graphcis ? Most notebooks don´t have Nvidia cards in them.

There are certainly chances but not in the coming months, I'm afraid.

Hello again, thank you for your work!
I am not IT-man, so maybe my question will be dumb

As I understand, RadiAnt uses CUDA cores from NVIDIA cards to render.
But there is another method - OpenCL
And AMD makes an utility to convert CUDA code to OpenCl

github.com/ROCm-Developer-Tools/HIP

What do you think about it?

how to download the beta version?
can some one post the link ??

@Lukash

ROCm is only supported on Linux...

@Free Guy, not so, any more

Beta versions are only available ...when they're available ;-)
We'll probably see one in early 2022.

hey, first of all thank you for all the amazing work!

I'm planning my new pc build and i was almost going for an AMD GPU till i asked myself..."what about RADIANT?"

So I'm writing you to be sure that the only graphics card supporting GPU acceleration for 3D VR mode are still the NVIDIA one (since last post is more than 6 month old)
If so i have no choiche but buying one of those ;)

Thanks for your kind words! Yes, still only NVIDIA cards are supported for GPU acceleration.

Hello! Are there any plans to enable GPU accelerated volume rendering for AMD graphics cards? If not, can you provide an explanation why? Unfortunately, I don't have the ability to choose the graphics card in my workstations (corporate), and for some reason they choose AMD.

Thanks!

Does NVIDIA RTX A2000 6GB support GPU acceleration in 3D

@Ben- Veterinary Radiologist

NVIDIA provides CUDA SDK which makes easy for us to develop efficient 3D VR/MIP engine.
There is no similar solution from AMD.

@wwj

RTX A2000 should work just fine with RadiAnt.
