What problems could have Filter Forge trying to use GPU acceleration?

I still wonder and would want to know what problems are for FF INC. developers and programmers to be able to use any kind of GPU acceleration inside Filter Forge

I really do not know how difficult and complicated can this be to add this feature of GPU ACCELERATION to FF and what amount of work would be needed, but seeing that I think that the Filter Forge Team are expert programmers, they could be able to find a solution to this.

I asked about this in April 2011 after the release of the FF 3.0 beta

We spent at least a year trying to port FF to graphic hardware, but no luck so far -- the current FF rendering architecture and multithreading were built for X86, so it doesn't lend itself well to GPU porting.

Sorry for my ignorance in programming, but if expert programmers have not been able in a year to solve this, where is really the problem?

Why most of the new graphic plugins has been optimized in somw way to be much faster inside Photoshop CS 5?

EXTERNAL GPU RENDER ENGINE MADE BY THE FF DEVELOPERS TEAM?

If not possible to modify the inner code to add the GPU rendering, Could FF use an external app for transfering the data fr om the main FF core to this external application that would be done also by the FF developers team ?

I know that some photoshop plugins do not have ONLY ONE PART and they can have two or three parts interconnected to make the final result.

Also this is used by some 3D software that all the configurations, settings and design is made in the main program (or plugin) and then to have the final result all the data needed is transfered to another software application to render it.

I think that having GPU acceleration could help really much to FF and be MUCH faster

Pixel bender for Adobe Photoshop is a great example and comparable in some way to FF because the users can make their own filters and submit them to the Adobe online Library.

The main differences are

Positive is that has GPU acceleration and all the previews AND renders of high resolution images are done in REALTIME, zero waiting, or one second.

Negative: that is much more difficult to make your own filter and the resolution lim it is 4000x4000 (although can be used until 5000 x 5000 sometimes)

OPENGL OR NVIDIA CUDA ACCELERATED PREVIEW ZOOM

The IDEAL woul be like other software that have now deleted all this about zoom, and changed it this preview levels to just ONE level, because it is a OpenGL, OpenCL and/or with Nvidia Cuda so you get a smooth and real time zoom preview to any level.

If You want to know what I am talking about you can see what Adobe have done in Photoshop CS5 with Nvidia Cuda

Please see the videos examples in this page here, just sel ect Zoomimg and Scrubby Zoom, as you can see they are very fluid ONE level zoom, or thousand levels zoom, whatever you want to consider

FILTER FORGE CANT BE COMPARED TO PHOTOSOP BECAUSE FF NEEDS TO RENDER THE IMAGE?

You could tell me that is not the same to compare FF to Photoshop, as FF needs to process all the commands of a filter, but i think also that when making a processing of the images it must also follow instructions given.

Perhaps could be said that FF needs to RENDER the resulting image before showing the final image, and Photoshop does not need this, but then how Pixel bender can do it in realtime ?

ACELLERATED PREVIEW ON PROGRAMS THAT NEED TO RENDER

Well there is a better comparison for Filter Forge preview and are the newest video software that ALSO needs to render the final result before showing it to the user.

I know of course that you can´t compare at all still images of FF to video animation, BUT if you look at the videos, is the same in some way what happens in FF trying to render the final image

I am talking about the Adobe After Effects CS5.5 and Adobe Premiere Pro CS5.5

Sorry that there are no videos for plain and normal GPU, but you can get an idea with the Quadro series cards.

In AfterEffects is like in Filter Forge that it needs to calculate a lot of things and make a pre-render of all the image before making any kind of zoom.

Please, see the Camera zoom video difference.

Also, although really different, is Adobe Premiere Pro

There is still not answer on why is not possible to add GPU acceleration to FF

Please, Please, could Vladimir or anyone else be so kind to explain it

Thanks very much

I do not care anymore WHY is not possible, because it really does not matter, what is important is if FF Inc. will have GPU support inside FF 4.0, which as said by GMM there is a confirmation that this will NOT happen, so there is no point in contiue asking WHY this will NOT happen.

I have decided to not continue requesting for faster FF because FF Inc. will not be able to do it and I have not any hope that this will happen so I have taken a decision that you can read in this thread here

why is not possible to make it GPU based. What are the technical reasons that makes this impossible.

I asked this before in another thread, and got no answer from FF inc. It's not like I could help them solve the technical issues or anyting, but I would just like to know what's the problem...

Totte, thanks for you insight about this. It's allways nice to hear from someone who actually knows what he's talking about

And you have some good points in your post. Iff FF team haven't figured out how to fix existing bugs, there's no point in adding new ones
