General / Bake Shapes onto Models Texture

« on: December 01, 2023, 01:47:38 PM »

I was wondering if there is a possibility to blend shapes into the texture of a model,
so that an exported textured model still shows the shape in any viewer.

General / Export multiple measured profiles at once to one or multiple files

« on: September 11, 2023, 02:35:32 PM »

When creating multiple shapes as polylines on a DEM i'm able to export each of them as profile via right clicking the shape --> Measure --> Profile --> Save [to different formats].
For a lot of profiles i have no clue how to export multiple [e.g. all selected profiles] at once into MULTIPLE files. I would also love to know if it's possible to export multiple profiles to ONE output file.

Any hints are appreciated
Thanks.

Feature Requests / Orthomosaic creation advanced cylindrical projection with axis

« on: September 11, 2023, 02:27:58 PM »

I came across tasks where i reconstructed a rock wall along a railroad from UAV images.
For this purpose i use metashape to create a vertical orthomosaic facing towards the rocks via a cylindrical projection.
It works okayish when the rock wall can be described as an cylindrical shape. It's stil a pain to set up an ideal solution for the projection cylinder since there is no exact visual feedback, when using the current region option. Setting up markers for the cylindrical projections seems to be a bit more precise. However, since the radius is mostly realy huge, markers would be outside of modeled area and hence couldn't be set in the model view.

Setting up the cylinder through manually adjusting the region is a bit imprecise specially when the radius needs to be huge like in the attached screenshot.
It would be great if it's possible to use an imported shape (circle) that could be easily prepared in GIS, or have a code snippet that uses a shape to modify the region along X, Y axis leaving only the Z axis and height for manually adjustment.

Furthermore for even more flexibility it would be awesome to make use of an polyline feature that resembles for example a railroad and use that to approximate multiple cylinders for cylindrical projections that gets composed to a single orthomosaic with minimal distortions for each part of the polyline. CC is able to do exactly this with a point cloud, however having this feature for orthomosaic creation within metashape would be great.

Any ideas for that or code snippets to get closer are highly appreciated.

Thanks.

General / Performance Recommendation for GPU Upgrade or a full make-over neccesary?

« on: April 03, 2023, 11:30:57 AM »

Dear Community,

i'm experiencing a bottleneck when processing uav images with metashape prof. that i might consider to be due to the used GPU [Quadro P4000 8G] that seems to be not very competetive for FP32 operations. It's most obvious on projects with a lot of images ~1500 @20mpx cos processing also with medium quality could take multiple days.

AMD Ryzen 9 3900XT
Asus TUF Gaming B550-Plus
32G DDR4-3200
nVidia Quadro P4000 8G

To boost performance it seems reasonable to upgrade the GPU. However, i'm not able to assess whether it would be better to go with RTX 3090, RTX 4090 or even with 4070, 4080 or some Ti variant since prices and capabilities are not that intuitive esp. since i'm not sure what GPU-feature metashape appreciates most.

Is there any experience or technical based recommendation for an upgrade for the workstation that also considers price–performance ratio. Or isn't the GPU the only bottleneck in the system and there is more to do?

Thanks in advance!
