General / Radeon RX 480: 4GB or 8GB version?

« on: May 03, 2017, 02:56:15 PM »

Hello @,
I am thinking to get a Radeon RX 480 for my Linux system and I find that this device is available with 4GB (cheaper) or 8GB (more expensive). Now I am wondering if this affects speed in Photoscan. Who can tell me: if I buy the 4GB card, will it be significant slower than the 8GB card?

General / Where has my OpenCL devices gone?

« on: December 21, 2015, 08:37:21 PM »

Have OpenCL and Photoscan Standard installed on my (SuSE) Linux PC some times ago. I found my OpenCL devices in PhotoScan and was able to use them. Log was reporting GPU usage. Now I was re-checking because I missed GPU in logs and dont find them anymore. I checked my running Photoscan using "lsof" and see that libOpenCL library is attached with the running executable. How to debug this?

Details:

Graphic boards:

root@egon:/opt# lspci | grep -i vga
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] BeaverCreek [Radeon HD 6550D]
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM]

ATI packages installed:

root@egon:/opt# rpm -qa | grep fglrx64
fglrx64_graphics_SUSE132-15.300.1025-1.x86_64
fglrx64_xpic_SUSE132-15.300.1025-1.x86_64

fglrx64_opencl_SUSE132-15.300.1025-1.x86_64

Running photoscan process:

tom@egon:/home/tom$ nohup /opt/photoscan121_2278/photoscan.sh &

tom@egon:/home/tom$ jobs -l
[1] + 16919      Running                 nohup /opt/photoscan121_2278/photoscan.sh &

tom@egon:/home/tom$ pstree -p 16919
photoscan.sh(16919)───photoscan(16924)─┬─{LoaderThread}(16928)
                                       ├─{photoscan}(16925)
                                       ├─{photoscan}(16926)
                                       └─{photoscan}(16927)

tom@egon:/home/tom$ lsof -p 16924 | grep CL
photoscan 16924  tom  mem    REG              254,0    27432 1206555 /usr/lib64/libOpenCL.so.1

But when I open "Settings" -> "OpenCL" in Photoscan, I see no GPU devices listed.

Any help is recommended.

General / What can I expect from a 1000 EUR PC?

« on: December 20, 2015, 07:42:04 PM »

Hi Folks,
playing with PhotoScan standard and dont like to spend so much money at the beginning, I am wondering what I can expect for ~ 1000 EUR. I understand that GPU cannot be fast enough and RAM cannot be much enough.
Currently I am playing on a PC, having 16 GB of RAM and this is the maximum, while runs start crashing when I add more images.

Does anyone have a suggestion for a configuration which is worth it's money?

Thanks for any suggestions.

Feature Requests / What features can you provide for a ~500 EUR release?

« on: September 03, 2015, 10:22:48 PM »

Hello,

I am playing with Photoscan Standard and it's really a nice tool. What I am most missing is creating Orthofoto (from buildings for example) and measurement tool + scaling. In general, I think Photoscan has too few features for me and Professional Edition has too many features.

So could you imagine to release some kind of Photoscan Medium which is tailored for the needs of  architects?

Regards, Tom

Bug Reports / Photoscan Standard Linux 116 and 120pre2149: Incorrect display

« on: September 03, 2015, 10:16:12 PM »

Having some photo series of buildings, creating the whole workflow, but dense cloud is only partially displayed in DenseCloud-Mono colour and in textured view. This was with release 116 and I hoped the new 120 release might have fixed that but here it's the same. As the screenshots are too large for upload, where can I send them by mail?

General / PhotoScan on Sun Sparc hardware?

« on: July 29, 2015, 09:40:48 PM »

I have some Sun Sparc hardware which is mostly unemployed. Did Agisoft ever try to run PhotoScan on Sparc hardware?
