General / Re: FBX Export - markers?
« on: March 27, 2017, 04:08:20 PM »
In the next version it should be possible to save markers in the FBX model export. Also model units and axis orientation would be specified properly in the exported FBX.

Sounds great! What is roughly the timeline for the next version?

Any updates on this?

Feature Requests / Gradual select By Angle for polygons
« on: March 27, 2017, 12:26:40 PM »
In order to clean up a dense reconstruction, a 'Gradual Select > By Angle' would be great.

So we would select a bunch of polygons, then run this new tool and get a slider to set a crease angle.
The polygon selection would be grown until the algorithm encounters a polygon whose angle to the already selected polygons is greater than the selected crease angle.

This tool should also run in 'deselect' mode, such that we can region-select a larger group of polygons, and then use the tool to deselect planar parts. All the non-planar parts could come from noisy or interpolated data, and this tool would allow for easy selection and deletion of such parts.

Feature Requests / Some basic 3D modeling tools with camera projection
« on: March 27, 2017, 12:07:23 PM »
I constantly find myself wishing for some simple 3D modeling tools inside of PhotoScan, in order to fix up some glitches in the dense reconstruction.

While I can easily export the mesh and edit it in some 3rd party application and bring that back into PS again, it would be MUCH better and faster if I could do the modeling while the camera projection is active inside of PS, so I can precisely see where to move my geometry such that it nicely aligns with the color information.

Some suggestions for such basic tools: a Cut tool, an Extrude tool, a Move/Rotate/Scale tool for vertices/edges/faces

Feature Requests / Volume carving tools
« on: March 27, 2017, 12:02:35 PM »
It would be really helpful if PS had some tools to draw outlines in individual photos and then use those outlines to do some sort of volume/space carving (by simply intersecting all the cone-like 3D structures that you get by extruding each outline from the camera position).

This would allow to quickly reconstruct some user-defined volumetric shapes that could optionally be refined by dense matching?

Feature Requests / Tools for wall surfaces
« on: March 27, 2017, 11:58:49 AM »
PS is great for organic objects, but I am having a very hard time getting good results for walls. Interstingly, walls would be really simple to model, but the workflow between PS and a 3rd party 3D app is pretty cumbersome.

It would be great if I could help the dense reconstruction in PS by indicating regions that contain a smooth, even, uniformly colored wall (maybe by picking two parallel lines on the wall?).

With such a tool, we could help the reconstruction for cases where there is little pixel information, but easy large-scale information...

What's the expected overall size of your objects?

Not sure changing focus is really an issue, but you really need to make sure all camera poses are known very precisely, at least for some photos.

From what I can see, the mesh interpolation is the issue, but if I switch it off it hangs during texture allocation because there are so many small fragments to texture.

Interesting. FWIW, I just ran into my own issue with mesh interpolation, related to memory problems.

General / Re: Crash to desktop while reconstructing mesh

Do you have swap enabled in your system? It looks like the process is automatically killed when it exceeds the RAM limit.

Now that's slightly embarrassing... - my page file was set to 500MB by the guys setting up the machine for me, and it was never changed to anything appropriate later on! I have increased the swap to 64GB, let's see whether this will help around the memory peak.

Thanks!

Also to note: I can split the chunk in two and reconstruct a mesh for each independently without issues (at High detail, with interpolation on) just by reducing the bounding box size for each chunk accordingly.

Seems weird to me that such a simple procedure works and isn't built into the program.

I can confirm that the crash is related to using Interpolation.
Attached is a screenshot of what taskmanager looks like when a crash occurs, while doing a 'low' mesh resolution but with interpolation on. Without interpolation, this works just fine (but the result is pretty bad due to many tiny holes).

It seems the "interpolation' is causing the problems? Without it, I can build a mesh at low resolution (1 Mio. faces), with it enabled, I get a crash (and an error message this time). Attached is the log.

This also works for High Resolution (9 Mio faces), but only without interpolation.

Follow-up: From inspecting the Event Viewer, it looks like the system is simply running out of memory (64GB?!)...
A bit weird not to see any warning message, but maybe the project is too large?

Do you have processing log for the operation or probably you have submitted the crash report?

I don't see any option to submit a crash report - how would that work? The crash is immediately to desktop, no warning whatsoever.

Attached is the log file I just generated right before the crash.

BTW, I also noticed it is crashing Firefox, too...!

Also what are the computer specifications and what were the mesh reconstruction settings used.

Win7 64bit SP1, 64GB RAM, GTX 1080 with 8GB VRAM, 24 core Intel Xeon E5-2687W v4 3GHz

Settings for dense mesh creation were:
Arbitray, Dense cloud, High (about 9 Mio. faces), Interpolation enabled, all point classes (I don't have any in the project)
