Im sorry in the original post i posted wrong question (on wrong forum) about zbrush :-D... I have updated the first post with the originally intended question about agisoft photoscan - how to temporary hide selected points in dense point cloud...

2
EDIT:

Im sorry i posted the wrong question... my question was: Is it possible to hide selected points in dense point clouds in agisoft photoscan? If one needs to hide selected points so he can better cleanup hard to acces parts of the model (which were previously blocked by hidden points)...

And once the cleanup (deleting on unwanted HARD to acces points) is done, than re-hide (show again) the previously hidden points (in dense point cloud)? Does agisoft has such functionality? (if not, why :-)? seems like a usefull feature)?

Thank you

General / Re: Performance diff. GTX 1060 vs GTX 1070 in photoscan...?

Thank but im not an idiot :-). There many game benchmarks, but sadly, gtx 1070 performs worse in profi applications, where there are NOT many (or any?) tests at all...

I didnt find practicaly any, thats why im askign here, if someone didnt test them already?

Does anybody have an idea or actual numbers, whats the speed improvement in photoscan when using GTX 1060 6 GB vs GTX 1070 8 GB?

Thank you

Ok so what software would you recomend for cleaning dense point cloud and then mesh generation??

Thank you

Thank you, i will test it ASAP :-).

General / What software for cleaning Dense Point Cloud?
« on: October 20, 2016, 04:11:47 PM »
When one generates dense point cloud and there are a lot of points that need to be deleted (the whole point cloud "cleaned"). some points are out of the actual scanned object but some are near or even connected with the point clouds of the actual scaned object.
One can "clean it" in agisoft, but i believe that there are far more capable software for cleaning that the capable with agisoft (can import a large ammount of points from agisoft and then after cleaning export them back into agisoft).

What software would you recomend for this?

Thank you :-)!

So it should look like:?

Code: [Select]
doc.save()
print("Processed project: " + project_name)
chunk.exportModel(path + "/" + project_name[:-3] + "obj", texture_format = 'tif', texture = True, format = "obj")

else:
continue

General / Re: Actual Difference On Mesh "Normal" VS fixed Lens (Nikon)?
« on: October 17, 2016, 05:54:14 PM »
Hello

Thank for your reply :)!

Can i ask that camera and what default lens did you use? (i for example used nikon d3200 with default lens 18-55mm VRII)

Also, on what "level of quality" of dense cloud generation did you do these test? Was it medium or high or even ultra high quality (that quite important i think)?

Thank you :-)!

General / Actual Difference On Mesh "Normal" VS fixed Lens (Nikon)?
« on: October 16, 2016, 09:40:21 PM »
Does anybody done (and i believe someone had to) and has info and even better pictures of actual real differences on generated mesh/model when using "standard", "default" "adjustable" lenses that come standardly with your DSLR camera (18-55mm lens that came with my Nikon D3200 for example) in comparison with FIXED lenses?

I know there is difference when looking on the pictures themselves but i have never actually seen any real test/comparison of meshes of the same model that was captured once with the default lens (18-55mm, at 35mm for example) and once with fixed (35mm lens)?

Is there any actual difference on the mesh? Is it big? Did somebody did this test or have some pictures?

Python Scripting / Automatic (batch) export of model with texture?
« on: October 15, 2016, 10:07:39 PM »
Hello i need a code/script allowing me to export automaticaly the generated model/mesh as obj with JPG (or TIF) texture. Im not a scripter but i found this script that allows a lot of batch process i didnt try it yet but i believe it should work:

Code: [Select]
import PhotoScan, os

path = PhotoScan.app.getExistingDirectory("Please choose the folder with .psz files:")

print("Script started")
doc = PhotoScan.app.document
doc.clear()
project_list = os.listdir(path)

for project_name in project_list:
if ".PSZ" in project_name.upper():
doc.open(path + "/" + project_name)
chunk = doc.chunks[0]

chunk.matchPhotos(accuracy=PhotoScan.HighAccuracy, preselection=PhotoScan.GenericPreselection)
chunk.alignCameras()

chunk.buildDenseCloud(quality=PhotoScan.HighQuality)
chunk.buildModel(surface=PhotoScan.Arbitrary, interpolation=PhotoScan.EnabledInterpolation)

chunk.buildUV(mapping=PhotoScan.GenericMapping)
chunk.buildTexture(blending=PhotoScan.MosaicBlending, size=4096)

doc.save()
print("Processed project: " + project_name)

else:
continue

print("Script finished.")

Could someone write additional line that after saving the file, it will also export the mesh as obj with generated texture (tif) for each *.psz file (with the same name as the file (or some unique name).

Is this possible?

Thank you a lot :-)!

General / Re: What programs can save *.rcs *.rcp point clouds?
« on: February 08, 2016, 04:50:53 AM »
Thanks dave but i have found that forum even before on my own, it really doesnt help, as far as i know, recap is not anymore available as freeware in any version (?) And the forum doesnt say if Revit can actually export rcs or rcp... So can someone help (tell me what program fopr sure does)?

General / What programs can save *.rcs *.rcp point clouds?
« on: February 07, 2016, 02:58:53 PM »
I need a point cloud from a friend to get into my 3ds max. He uses agisoft photoscan which is able to export point clouds into many formats, but sadly none is compatible with 3ds max. 3ds Max allows to import only rcs and rcp formats which are from autodesk recap (which i do not own and it isnt free AFAIK).

So i want to convert the point clouds from one of the formats supported by agisoft photoscan in some OTHER software to rcp or rcs (agisoft cannot save directly to rcs rcp) and import that into 3ds max.

What ALL programs can save/export into rcs or rcp formats? Recap, what else? Autocad? Inventor? Something else...even free? (believe it or not, this information is hard/unable to be found even on the internet).

Hello, im playing with the idea of building my own basic 3D scan system using photogrammetry (agisoft photoscan probably). Only around 20-25 cameras. Currently it looks like i wont be able (price wise) to get the cameras to be all the same type. I will probably have to have 3 different cameras, all from the same vendor (cannon ?) and all circa in the same price range.
But besides vendor and price range, the cameras will range, in age (1st type is new, 2nd type is 3 years old, 3rd type is also 3 years old), and of course mainly in Mpx. The newer type would have 20 Mpx, the older ones (2 types)  will have 16 Mpx) . That means cca 3 types. If im Lucky i will end up with only 2 types, but still 20 Mpx vs 16 Mpx. Will this difference be problem for agisoftphotoscan? Can it handle it (mixing photos from 2-3 different camera types for one capture session (for one model))?

Will it work? Fail completely, or work but the result will be slightly innaccurate?

Hello, im thinking about building some rig for face scanning (just face scan, not full body scan, also "only" front and left right sides of head would do, i dont need the back side of head).
Could i do it with only around 25 compact point and shoot cameras each for only around 100 USD? For example this one: http://www.amazon.com/Nikon-Coolpix-Digital-Camera-Optical/dp/B00S9O476W

1) Would this be sufficient to get a good quality face scan (front, right and left sides of head)?

2) Would this be even possible? I need to trigger all cameras at the same time, it this even possible with these 100usd compacts?
