It turned out that the computer wasn't reading 8 gigs of RAM, which explains why it only went up to 24. We pulled them out and put them back in and they worked. Actually the medium setting seemed to work OK. The dense cloud at "high" was 71 million points.

I built a new system with 32 gigs ram. It wa processing OK with the hi-def cloud... but then got stuck at "6% done" for a long time...at 24 gigs of ram -but the CPU was only working at 4-5%. I canceled the processing, but it wouldn't cancel so I forced the program to close. The whole system had crawled to a stand still. For a 1/2 hour after closing, my computer still wouldn't allow other programs to start and kept crashing windows Explorer. Even task manger crashed. I'll test my ram as soon as I can with memtest86

My 5 year old motherboard is dying so I just bit the bullet and upgraded to a Core i7 5960X. I use a lot of multi-threading software (Premiere and 3Ds Max).  I just read this: http://www.pugetsystems.com/labs/articles/Core-i7-5960X-vs-4960X-Performance-Comparison-588/  which vindicates the 5960X for these multi-threading software programs.

The medium setting is not too bad.

Now I need to figure out how to "close" it for printing with Meshmixer and 3D Studio. I will attach an image with a "porcelain" material mapped on it instead of the photo bitmap to show how accurate it is.

...I have put a couple of these printed scans in this exhibition http://www.sanderson.co.nz/Exhibition/350/Brit-Bunkley/Social-Realism.aspx

I am adding another 12 gigs of RAM tomorrow. that should help.

I tried again and the point cloud came out OK (at 75 million points- and I saved it this time), but when I tried to "build mesh"... even at a low poly setting it goes to 5%, and then the RAM immediately goes up to over 19 megs and it seems to stop there and freeze.

Do you mean I should perhaps build the dense cloud on "medium" instead of the default "high"? Would playing with the gradual selection and re projection error settings help?

I had 99 photos at 18 megapixlas each. I'm not sure what the Height-field mode vs Arbitrary mode means on the link you provided.

Hello, I just made a dense cloud of a Soviet monument stele in Berlin. It took a couple hours, but all was fine when complete. However I tried to make a medium mesh (4 million faces) from the cloud. When I came back after 10 hours of processing the mesh in the morning it was at 10% and was using most of my  20 Ram of memory. It couldn't handle the processing. I have never seen that before today. I tried for about 1/2 hour to cancel the processing with no success, and then used the Task Manager to close the program, losing all previous processing. What would you recommend – get more ram, try chunks (whatever they are..?) using my laptop as well, lower the mesh quality?

Although I like the degraded look artistically, I would like a better resolution. How about zooming in? I don't think I could get to it with a pole at the location ...and how would I shoot it? Or could I keep the 35mm setting and just get closer. I guess my main question is that it's OK to get just part of the object close up in some shots and throw it in the mix?

I put the same image on twice. sorry. Here's the other.

schematics of 2 ways to photo the line of columns. Which is best, or do I do both?

General / scan in a line of about 8 columns?

« on: September 23, 2014, 10:53:00 AM »

How would I scan in a line of about 8 columns. Would I scan in them as a group from the same angle and then at an array?
                                 
And would I  then photo each individual column -  with photos taken all around it (masking the single column out, assuming people are wandering in the background)?... And then add detailed images: photo the top ? of a single column taken all around it, and the bottom ? of the column all around – since columns take up a small portion of the frame. I’d assume that all photos need the same focal length? …and then I’d throw all of these images into one Phohoscan project and process?

I am attaching a few images, including a single bullet hole ridden (ww2) column taken by masking out the others (with no close-up detail shots), and a rendering in 3D Studio of the final column (using my own bitmap, not the orginal...in order to see what it looks like in a 3D print). Would I have improved it by taking details of the top 1/2 and bottom 1/2?  Thanks in advance.

General / Why are some photos aligned, but similar ones are not (with NA next to them)?

Why do some photos process as aligned, but similar ones are not (with "NA" next to them)? Can they be improved to align? I am attaching two examples. I see that the masking is not perfect, but that should make a difference should it?

I aligned it again removing the second set and got this.

Cool scan by the way!
