Hello Arkifabio,
Sorry for not answering in your thread.
I'm calculating a model with metashape standard edition, 127 drone photographs, medium quality.
Everything is fine until the generation of the dense point cloud, acceptable times despite a gpu nvidia Quadro K1000 but I have problems at the time of the generation of the mesh that becomes very slow at the time of decimation, once the generation is finished (about 3 hours), the console foresees about 3 days and 15 hours, and the system uses all the ram and 95% of the hard disk, with a low CPU usage
The system is a dell precision m4700, i7, 32 gb ram, hd ssd samsung.
What can I do to reduce the time for decimation?
Usually for better understanding of the issues we ask for the processing log related to the operation and some additional information regarding the project and processing parameters used. In this particular case it would be helpful to have the information regarding the resolution of images and number of points in the dense cloud.
You have mentioned that the CPU activity is close to 0%, but if the RAM is fully used, it means that the processing is using disk swap due to insufficient RAM to complete the operation.
You can skip decimation phase for Arbitrary surface reconstruction option by using 0 value for custom face count field.
If it is possible, you can send the project with the dense cloud to us and specify the processing parameters used for the mesh generation, so that we could check the memory consumption and see, if there are any issues with the project/processing that causes high RAM usage.
