General / Rain simulation
« on: March 13, 2024, 02:37:13 AM »
Hello dear Metashape users,

I was thinking to simulate how water flow on a steep terrain.

Let's say I have the 3D model and the DEM, what's next to do a 3d simulation?

- What software are you using?
- How are you modelling soil water absorption?
- What else are you considering for such simulations?

Thanks all

Feature Requests / Options to compress FBX+Textures
« on: December 30, 2023, 02:15:42 AM »
Would be nice to have an options to export a .zip file with the FBX model and textures, so that can be easily stored / uploaded to Sketchfab

Feature Requests / Support for custom Shaders
« on: December 13, 2023, 05:34:57 PM »
Would be nice to have Custom Shaders support in the 3D view to see special effects (ex. Meshlab). Some users may use this for Depth Maps also.

Bug Reports / Metashape 1.8 / 2.0.3 - Export undistorted images
« on: October 24, 2023, 05:09:18 PM »

I tried File/Export/Convert Images to export undistorted images. The "transform to initial calibration" is checked, but output files are identical to input images.

In Tools/Camera Calibration I have set the initial with the calibration data (so now is identical to the Adjusted tab), but this seems not to work.

Here the calibration images I used and attached the screenshoot of the calibration parameters Metashape calculated.

Bug Reports / TIFF/LAB files displayed in Black White only
« on: August 27, 2023, 11:57:46 PM »
I have photos in TIFF/LAB format (can be converted/created with Photoshop, Affinity Photo, etc..) to retain the full color gamut from RAW files.
Metashape can open them but they are displayed in Black and White only. The texture generated is monochromatic too.
Would be nice to have full support for this format
Thank you

General / Target and epipolar lines
« on: June 19, 2023, 12:08:23 PM »

Is there a way to show target points on epipolar lines only? I mean the dotted red lines that tell you where can be a point. I would like to review all these red lines to adjust points.

Thank you

Feature Requests / Duplicate and Decimate

I would like to have a command to do both at the same time from the GUI

General / Iterative workflow
« on: May 05, 2023, 02:28:18 AM »
Hello all,
I usually optimize the model by removing camera to fix some textures issues, adding some manual markers to fix some problematic areas, and so again..
The problem is that after disabling camera to fix the texture, I can't easily re-do other steps because camera are disabled and with many camera changing their status it's difficult to revert back every time. Hope I explained the issue. Is there a better way to iteratively optimize the model?
Thank you

Camera Calibration / Pixel size
« on: April 29, 2023, 01:55:59 AM »
I have some images that are downsampled from the native sensor resolution of 1920x1080 to 1280x720 to keep the FOV (Field of View).
The sensor pixel size is 1.4umx1.4um, what should I specify in the camera calibration dialog?

I was thinking:
1920x1080x1.4x1.4=4064256 (pixel area)
sqrt(4.41)=2.1um=0.0021mm -> equivalent area?

What metadata are used to calculate the pixel size?

Python and Java API / Importing Depth Images - Measure Unit
« on: April 28, 2023, 07:10:11 PM »

In v1.8 I managed to import depth images as 16 bit .tiff files by using a script based on How can I specify the measure unit?

For example, how can the software understand if a value of 1 is 1mm or 0.5mm?
Do I need to have some metadata on the .tiff file?

Thank you,

General / Virtual Point
« on: April 28, 2023, 01:03:31 PM »
I have some markers in my images and I have a base-station that is not visible in any image, because removed before shooting.
I have marker/base-station distances recorded with a laser rangefinder, and I would like to know the best workflow to add these constraints.
Thank you,

Camera Calibration / Focal Point X and Y
« on: April 26, 2023, 05:52:15 PM »
I have some calibration data about a lens, but I can't find a way to specify Fx and Fy, there is a single F available.

Python and Java API / Camera group by camera distance
« on: March 05, 2023, 02:43:09 PM »
I would like to automatically create camera groups based on the "average" distance of camera from the mesh / tie points. Is this possible?

Python and Java API / Script Split in chunks
« on: March 05, 2023, 02:39:02 PM »
Is the "overlap %" mandatory to correctly merge back chunks by using the script?

Feature Requests / Disk performance optimizations
« on: February 25, 2023, 08:09:52 PM »
I noted that if I'm working on an externally stored project files are not read while GPU is processing.
I think this can be a good optimization, while file A is processing, file B is read so that GPU won't have to wait to process B.
