Crashes and black textures

Postby Vito » Wed Mar 18, 2015 2:34 pm

Hello, I am a newbie, I have purchased DAVID SLS-2 and I am doing 3D scans of bones for my research. I am using Windows 7 x64. I am satisfied, although I have some problems that are probably due to bad calibration (in complex objects like crania it is very difficult to align all the scan, and a lot of work is required to recognize deformed areas). However the bug that I am reporting regards fusions and textures. I am fusing 30 scans of a humerus, and when the process is done (either at 500, 1000, or 2000), when I try to visualize the textures the program crashes. If I save before visualizing the textures, and then open the obj file, the program crashes again when I try to visualize the textures, or gives me all-black textures.
If I open the obj in meshlab, everything seems fine, the 3D reconstruction and textures are there. This reassures me a little bit, because those are kinda ancient bones and it would be impossible for me to go back and scan them again...
However, if I try to open the ply file, it tells me "error, unexpected eof", while the stl loads, but without textures.

What might it be? Is it a known issue? That happens in two different x64 windows7, a laptop and a desktop (both are powerful, especially the desktop which has a recent i5 and a R9 290x)

Thanks!!
Vito

I purchased David 4 today hoping the issue was solved, but the problem persisits, and only with specific sets of scans. Others are fine, I am able to fuse and then toggle texture without crashes...
I have also tried to fuse each single scan of those sets, to see if one would make the program crash. Nope, all those single scans fuse fine...

Vito. You should send an email directly to tech support. They are pretty good at responding but don't always seem to be monitoring the forums.

Hi,
It seems we didn't get an e-mail...
I would assume that the amount of texture data (30 scans all fused together) is too much for the 3D view. Maybe system is out of graphics memory?
