DAVID 3.7.0 beta2: 64-bit!

Postby Sven » Fri Feb 15, 2013 4:13 pm

-
EDIT 2013-03-13 by Simon:
The final release of DAVID 7.3.0 (including 64-bit) is now online and the beta version is obsolete!


Hello everyone,

Finally we have finished the new beta version, DAVID 3.7.0.3558 beta 2.
The download is larger because... there is an additional exe file "DAVID3_x64.exe" in it... :D
Edit: download removed

Main improvements since 3.7.0 beta:
:arrow: 64-bit version (Edit: not for XP64) (note: Canon EOS supported only in 32-bit version)
:arrow: fixed crashes during alignment
:arrow: speedup also for XP
:arrow: new alignment option "Contact Pair Selection" (see below)

and more:
- 3D View: Buttons for show/hide texture, edges, normals
- Calibration: More helpful error messages
- GUI: Some minor improvements
- GUI: Improved progress bar, and use it more often
- ...

The new alignment option "Contact Pair Selection"
The automatic alignment often fails when the object is too regular, does not have distinct shapes, or the scans have too little overlapping. Now you can help DAVID by clicking on two points (areas) that shall be in contact. It's very easy:

- Without "Contact Pair Selection", as before: You click anywhere on Scan A, then you click anywhere on Scan B.
- With the new "Contact Pair Selection": You click on a certain region on Scan A, then you click on the same region on Scan B. Like this you will draw a line between these regions.
CPS.png

When you click on these regions, the mouse pointer has a red circle. The size of this circle is relevant, it defines the size of the contact region. So when you zoom in, the region gets smaller, that means you are defining it more precisely.

Edit: Don't use "Contact Pair Selection" and "Use Texture" at the same time - will crash!

Please test! We are looking forward to your feedback. If there are no problems, this will become version 3.7.0.
:D

Great! I think we did look really forward to it!

But sorry for the question - did I may pass something? Where was DAVID 3.6? :)


Greetings!

Hi Sven,

congrats! Almost no problems here using 64 bit version (minor thing: after a global registration the text in the progress bar stays )

Ad ContactPair: For images tell more than words...see attachment.... Note yellow to green is NO overlap. Boarder to boarder simply fits perfect :)

Hi,

found a repeatable crash causing issue:
Here, using AlignMode Free+ContactPair+UseTexture makes DAVID crash (32 as well as 64 bit)
AlignMode Free+ContactPair alone, as Free+UseTexture works fine.

Hello Sven and partners

Great Job, very effective new alignment tool

I tried it on an one piece original scan in order to be able to check the quality of the alignment with minimal overlapping, so I did cut the scan in two pieces leaving an overlapping zone of just 4-5mm, then moved to arbitrary position one of the two, then free aligned using the new contact selection tool and it worked out at first attempt, then i combined them, so I aligned te original one piece scan to the group and checked out that it fit perfectly, no flaws at all, it is very good.

Next scan I try it with real partial pairs

This is a very solid robust answer to to the wish to reintroduce the 3 or more points alignment method, similar in concept, more powerful, easier to use and VERY effective, my sincere compliments.

By the way I tried the 64bit build, it does not work onto windows XP64, the message error is that it is not a valid win32 application :?: , which sounds strange as the OS is 64bit and regularly runs all programs which are 64bit

Is this build compatible also with WInXP64? Or it is compatible only with WIn7/8 64bit? (strange that no one even speaks of Vista anymore, but with all the service packs in fact became almost good as seven, I guess it is just repelling people for the very good fame)

Win XP64 is really rare so there is no significative loss of compatibility, I just do not know what imply as a difficulty to have it built also for XP64, I just ignore it, but if it is only a matter few options in the compiler and not much effort might be an extra to add.

I personally tend to still keep the ol'good XP64, very light, very stable, very powerful and no tricky "unsecurity settings" I do not need, but I think came the time to have a dual boot to Seven64, I have an unused license, but have to take the time to do it :roll: , I am too much curious to try the 64 version and see how mange large heavy scans I did.

BUG: I confirm MagWeb statment, on win XP64 in david 32bit >>>> free alignment +contact selection + texture = David hang and become irresponsive, must be killed

The 64 bit beta, now recognizes, and calibrates the point grey cameras, with USB 3.0. This is the 150FPS Global shutter. Running win 7, 64 bit pro. No need to run the Flycapture form Point grey.

Hi,
The 64bit beta is simply amazing. At 150 fps, the point grey usb3 will open a whole new structured light scanning experience. Would there be opportunity for scanning slow moving objects?
Do we also have to change the projector frame rate?

I am glad David offers 64 bit beta.

Which model Point Grey camera are you using? I'm thinking of upgrading.

FL3-U3-13Y3M-C

This is the global shutter 150 FPS mono model.

David will recognize the camera up to 1024X960 @60 FPS.

Actual frame usage with David is around 40FPS, using ICORE7, with 16 gigs of ram in laptop, using USB 3.0.

I have not had much time to do any testing or tweaking yet, may take a few days.

the 64 bit version works well here, the only thing i had difficulty with was, with the new calibration,
i find it a bit hard to see the calibration panel when setting the camera view, as it no longer projects white light.
Also once i'd calibrated, I hit the live view button, and it didn't seem to work, i ended up swiching back to the hardware set-up to get a look at whats it frame.
Am i missing something?

Hi all,

Thanks for your feedback! :D

3.6 was a USB version we had to push in just for the SLS-1. No official download release.

MagWeb wrote:minor thing: after a global registration the text in the progress bar stays

Thanks. My mistake. I have fixed it for the next version.

Hmmm, I have no problems with the Video Grabber. Which video codec are you using? Anyone else have that problem?

D'Oh! You are right, ContactPair and UseTexture don't really work together. Sorry I didn't see it earlier. Please don't use both at the same time. We'll find a solution...

illustrami.com wrote:By the way I tried the 64bit build, it does not work onto windows XP64

Ah yes... sorry. The 64-bit version won't work in XP64, only Vista, 7 or 8.
Can't fix that easily, so you will have to work with the 32-bit version.

illustrami.com wrote:I personally tend to still keep the ol'good XP64

Please note that Microsoft has decided to end support for Windows XP at the end of 2013. No more updates, no security fixes. So if that computer is connected to the Internet, you should update your Windows this year.

Dear Sven, dear David team...

David software is growing up more and more. Good.. Really nice feature is the latest tool for alignment.
Now you need the "cherry on the cake": the non-linear aligning tool! :wink:

Have a thought about... this can really move ShapeFusion into new level and let it to be sell as a standlaone software.

Just an idea (and not a new idea... hehehe)
Keep up your great and amazing work,
Mattia

whilst running the 64 bit on my win7 laptop, my settings are going a bit wierd
the advanced settings window is unreadable and it keeps changing to 1 frequency.
i tried overwriting the settings with a previous one but it still kept doing it.
once i had it set it seemed to function normally even tho i couldn't read the advanced settings still.
Can you suggest a fix or is it best to use the 32bit until more work has been done on the 64bit version.
Thanks..
