Split into Chunks for building Tiled Model ?

[Alain]

Hi

I had a "Bad Allocation Error" after building the Tiled Model (0.006m/px).
Maybe 0.006m/px is a bit to high ? I tried with 0.6m/px and it worked but the Model is mutch to rough.
Isn't it possible to split the Model into Chunks by Script like you can do for building the 3D Model ?

It's a "huge" Model of about 2000 Photos, Dense Cloud of 725'000'000 Points.
Hardware: 32 GB RAM, 8 logical Cores, Nvidia Quadro M2000M.

Does anybody know what to do to compute the Tiled Model in a useable resolution ?

Kind regards
Alain

Hi Alain,

If you don't check 'merge back' in the dialog box of the SPLIT IN CHUNKS Python script, then you should be able to generate a tiled model for each chunk.

All the best.

Hello Alain,

Can you please provide the related log for the failed operation?

Which parameters you are using for tiled model generation - what is the source? Specify also the number of points in the dense cloud (if it is used as a source) or number of polygons in the mesh model (if it is used as a source).

[Alain]

You see the number of dense points in my first post ;-)
I tried again but with "Mesh" instead "Dense Cloud" as source and it worked and also even faster :-)

Hello Alain,

Still the log related to the failed tiled model generation that uses the dense cloud as a source would be helpful for us to understand why the  process is terminated unexpectedly.

If you are using version 1.4.2 I can suggest to enable Fine-level task distribution for the Tiled-model generation process in the Network preferences tab - it would split the selected operation into smaller jobs (similar to network processing) thus the memory requirements would be lower, although the processing time may be slightly increased.

Hello Alexey

I guess the Error occured because the process reached the memorylimit.
Before, to create the Mesh I also had to split the Model into chunks to not reach the memorylimit.

Kind regards
Alain
