output quality regression? #1501

Open zeuner opened 1 year ago

zeuner commented 1 year ago

Comparing draft meshing results from both a build of the develop branch at end of April 2023 and right now, I noticed a degraded reconstruction. 3D features seen in the previous mesh are now missing.

Is this a regression in AliceVision's reconstruction logic, or are there different settings that should be applied when going to the newer build?

This is the current reconstruction pipeline:

I see the describer Types are set to sift, however in Meshroom dspsift is used by default
