Feature Requests / Allow saving bounding region

« on: January 23, 2023, 03:01:53 PM »

I know we can use script to copy region from one chunk to another, but it would be useful to save it so it can be recalled easier.

General / Re: Fill holes in pointcloud?

« on: January 19, 2023, 02:55:40 PM »

Build a watertight mesh from depth maps, and then build a point cloud from the mesh (by sampling) with the desired point spacing... this workflow tends to deliver a much cleaner dense cloud.

Bug Reports / Re: ... error reading pixel

« on: January 13, 2023, 06:58:19 PM »

Hi, Alexey, it happens consistently. New computer, 64gb ram. Sorage is ssd, Ryzen9, dual Gtx 1070ti, up to date Nvidia drivers... and occurs after depth maps are finished while mesh is being built. Will try same proj in my older computer.

General / Weird decimation

« on: January 13, 2023, 01:27:37 PM »

I've recently observed that during decimation metashape divides the whole mesh into regions and it looks it decimates diferently. It gives the impression that it sets triangle count per cluster as target rather than a global volumetric parameter for cutting the iterative reduction process, so it leads to very noticeable diferences in mesh resolution thus exactness between clusters.
I think there's room for improvement here.

General / Re: Dense Cloud to PTS (or e57, las etc) to RCS Problems

« on: January 09, 2023, 01:55:29 AM »

it shows just a long straight line of points

Very likely you are exporting geographic coordinates: lat/lon/elev and they are read in Recap as if they were X/Y/Z.
If you think a bit, you will surely understand why all your points look like a single line, or better, like a tall stack of points. They vary some metres in Z and barely move sub-microns in X/Y

General / Re: how to add an elevation offset to Point Cloud and to DEM based Point cloud?

« on: October 25, 2022, 10:16:37 PM »

Export the cloud with the offset (you can enter shift during export) and then import again.

Precalibrate your camera could be the best solution.

General / Re: Agisoft Metashape 2.0.0 pre-release

« on: October 16, 2022, 04:21:27 PM »

It is rather difficult to understand for me why steps towards the integration of lidar/laser scans and photogrammetry requires the removal of  the terms "laser scans", or "LiDAR" from all menus. Apparently import scans sounds too much explicit or specific, so it is better to call them depth images.
Why not "structured laser scans" versus "unstructured point cloud? Also why drag and drop scans over the chunk is still impossible?
Thanks for the update!!!! I'm eager to test it further.

Best for good russians.

General / Re: How to display 3D side by side in fullscreen ?

« on: October 14, 2022, 12:38:28 AM »

Are you trying to adapt some stereoscope? I do not recommend it: I did it some time ago and the stereo view was deformed and uncomfortable... I spent many days working this way and finally gave up. Later I purchased a true stereoscpic diplay based on dual monitors and a splitting mirror... and OMG, this is glory! I love it. I'm an absolute fan of stereo plotting it feels like diving into the reality. Seriously, forget split view. Aspect ratio gets wrong, Agisoft has done something wrong with the split view and I have already told them but they don't seem to care enough about old school stereo photogrammetrists. Get a stereo ready card and just let me know if you want a proper stereo display.

Feature Requests / back face color tint

« on: October 13, 2022, 02:45:50 PM »

Dear Agisoft devs.
I know there is an option for back face culling that works during orthomosaic creation hiding triangles with normals pointing towards the projection plane. It works well in some cases, but not-so-well for complex geometry where it often creates confusion when triangles in the hidden areas have normals towards the viewer.
I would like to have also an option for using a distinctive tint overlay for inverted triangles as alternative to culling.

The mesh is rendered darker for inverted faces, but it is not so much different to the positive face when texture or colour is also dark. It would be nice to have the color tint option also in the model viewport when looking at textured or shaded mesh.

Best regards.

Feature Requests / Re: Use Drawing plane as reference plane for exporting orthomosaic

« on: October 13, 2022, 02:20:15 PM »

It is already available. Select the same three markers used for drawing plane definition also for building the planar orthomosaic... or am I missing something?

If you can select a tie point you can filter photos pane "by points". This will tell you the photos it comes from.

Bug Reports / ortho view malfunctioning

« on: August 26, 2022, 08:05:18 PM »

Context: 3D model of a building mixing aerial and terrestrial photos. the project contains mesh, one projected DEM and several elevation façade planar orthomosaics.

My ortho view gets frozen when an orthomosaic is shown and I can neither drag (pan) nor draw. Zoom with mouse wheel also impossible, however magnification button works normally
If ortho view contains DEM, the odd behavior stops, and I can draw, pan, zoom etc.
If I switch to orthomosaic the problem comes back
But the weirdest finding is: if I de-default the existing DEM, then orthomosaic turns back to normal behavior, so it seems to be something related to DEM (projection) coexisting with orthomosaics (planar):

All with latest release.
Best regartds.
