Bug Reports / Re: Space Mouse does not work in OS X 12.3.1

Not on this M1 machine, on my Intel Mac, yes.

However, the spacemouse works fine in all other apps I checked so far (Cinema 4D, ZBrush, Blender and Shapr3D), so the general driver installation should be fine.

Bug Reports / Space Mouse does not work in OS X 12.3.1

While my Space Mouse works fine in most applications with the most recent driver, it doesn't do anything in MetaShape Standard right now.

HID enabled controller is enabled in MetaShape's preference, and the SpaceNavigator is also listed and found under controller. However, neither the buttons nor any of the axis work.

Any ideas what I could do?

EXR is not a display format, so the key question would be what is the purpose of these data for your application. It's not just gamma, it's the question which range of the values you choose to display.

Yep, a turntable setting in the alignment dialog could easily allow to create the model upright in the first place.

IMO, this doesn't even need to know if the camera points up- or downward. Basically the positions of each row of frames in a turntable describes a circle, which could be rotated to lie in the x-y plane.

In my case, the orthogonal views of blender were fine to align the models.

Also note that while the current version supports the M1, it is not enabled in the preferences by default. Take care to check both checkboxes on the preferences GPU subpage (labeled „Apple M1…“ and "Use CPU when performing GPU accelerated processing") and double check that they were actually set.

On my MacBook 16 this brought times to generate the dense point cloud from 1-2 hours down to 2 minutes!

Ok, thanks for your answer, at least I don't have to spend time looking for options that I don't have in the Standard version.

Best regards

I'm sampling the pieces of a historic chess game, which I photographed on a turn table.

After some initial struggles with the automatic camera calibration [do not try this with pawns or bishops... import the calibration from other pieces like the knight], this worked out quite well for my purposes.

The camera was on a tripod, so all the source images should have the same y coordinate. Though the cameras are correctly aligned with respect to each other, they and the reconstruction volume are rotated along the x axis by about 30°.

The only remaining issue I have is to orient the pieces along their rotational axis.

Any tips on how to do that?

Very helpful, thanks!

General / Adding photos/cameras to an existing folder
« on: August 30, 2018, 07:03:08 AM »
I'm dabbling around with Photoscan on a rather moderate setup (16 GB of RAM on a laptop), so I'm trying to limit the number of photos/cameras I use.

I start with a rather small camera count, and then have a first run. If I encounter problem zones, more photos/cameras are added to address those,

Now to my question:

Is there a way to add additional photos to the current folder of already aligned cameras, and then recalculate alignment / dense cloud without loosing the calculations that I already did?
