Bretchts New Blender Render Design

[leandrobp]

Just trying Cycles today. My first impression was it has a very impressive speed, as fast as Octane, then I just saw I was using CPU only, I change to GPU and... twice faster... and pure real time PATH tracing on the blender 3d view, no F12, no time lost on import-export.
Of course it's still very raw and buggy, but at the same time almost usable. There are already some animations popping up on youtube and vimeo.

Really hope RS guys hurry up with integration plugins!

I missed this post completely and I'm absolutely stunned by Bretch's dirty move. If I was you, I'd pass the NDA to your sharkiest lawyer right away and sue his ass if he finds it appropriate

... should have filed for patents, that's the only way to have protected the "concept". To be blunt, I don't think RS has anything to sweat. Stuff like this helps mature a company... call it growing pains.

Beyond that, I seriously doubt Brecht broke any laws or meant any harm to the RS people, he's simply not that kind of person.

Life will move on, it will work out in the end.

I simply don't understand some comments in this thread. This is a robbery.

Making something new is really difficult and although it wasn't a "copy/paste" they have stolen time and concepts in benefit of themselves (the foundation)

Keep the good working guys.

P.D. The case of Renault vs Ferrari in F1 two years ago was quite similar...

I don´t see any real problem or for that matter its not one that concerns the community. Brecht is said to be one of the good guys without malevolence, good enough for me, everything else is between him and RS.

Let´s face it, Cycles is Alpha, and although it has some similarities to Octane, which most likely comes with the underlaying theory and algorithms most likely, I doubt it´s serious competition for Octane. It might be that Brecht found some "inspiration" at RS that let him make a quantum leap, but beyond that:

Octane is far ahead techwise and isn´t tightly integrated into any tool.
Octane has a company devoted to developing it.
Brecht has other more pressing duties in the BF as core coder - so unless another genius walks by, Cycles will stay "under construction" for quite some time.
The BF and community calls for an OpenCL implementation, which will eat even more time.
Contrib coders will take a year to read into the code and understand the algorithms.

And I also do not think it will take away Octane's Blender userbase (at least not me for what it is worth), the problem lies within nvidia. The exodus of Blender users that, without wanting to sound condescending, actual make use of Octane, or need it, is linked to the OpenGL crippling of the 400/500 cards.
Many Blender users are absolute beginners or mediocre hobbyists and do not have the big budget but want Octane for whatever reasons and if it´s only to play with it.
So the cards (GF400/500) that are grand for octane, absolutely suck for Blender. And with AMD cards it´s awesome for Blender, but no CUDA.

That leaves RF with the few that got several nvidia cards already, a slower one for viewport from the 200 series, and a 400/500 for octane, or those with the money to either buy a fast Radeon for viewport and a fast Nvidia for CUDA, or simply have several machines - or those who got the big budget and buy Tesla Quadros but those are more likely the ones buying Arion or Shot!

So Nvidia takes the customers away from RS. I see Octane currently targeted at the guys that would like to work with one or two fast GeForce - which is impossible unless you use a DX tool or do low poly game modelling, where you don´t need octane.
For Blender the solution would be easy, we´d need a dev to replace the slow OpenGL calls with CUDA calls and make a "nvidia-version" of Blender.

And if Nvidias 600 Series is the same OpenGL crap, I see Blenders future in AMD and OpenCL raytracers.
Then I actually see only AMD or Quadro users in the future, where prior will not use Octane.

I am a professional, I use Blender and NVIDIA since almost 10 years. Where is the problem with Blender/NVidia.... i never had any.

As a sole Blender user (but slowly beginning to expand my software arsenal), I can guarantee you guys will have my support for years to come, simply because I think you're all great guys and I love Octane. Despite this hurdle I'm sure Octane and RS has a great future ahead of it.

I use nvidia for decades too, actually since the Riva TNT and only had a Radeon9800Pro once.
Last week I ordered my first Radeon again. I believe in whatever gets the job done. I also got a QFX3700, GTS250 but they are all too weak for High Poly stuff in Blender.
And Nvidia decided to cripple several of the GeForce cards OpenGL functions, one could assume to raise the sales of Quadro Cards, which do not suffer that shortcoming.
Funny enough, that the GeForce cards reach Quadro performance if you replace the crippled calls with Cuda calls.

If you check the history of the wiki article you´ll notice that the Problem section was blanked out a few times and restored afterwards.
The 400 and 500 series are awesome cards, especially compared to AMD`s Cayman chip, unfortunately it seems they where too awesome so they crippled them.
I contacted nvidia already but mostly got ignored or told it´s just the way it is. There seems to be no benefit of any sort for the way the cards work, only downsides for OpenGL.
No explaination from nvidia, no statement. Just silence. Most people don´t even know about it. And if their old 285 performed 4x better in OpenGL than the new 400/500 they start to blame the tool

I will surely not be forced by nvidia into buying quadros for plain OpenGL viewport performance.

So i think we are all agreed then!

ATI cards for display
Nvida cards for Cuda/Octane work.

Sounds like a plan to me.
