Convert crs slow on Linux

[jbak9141]

Hi Alexey,

I've been working a bit with PhotoScan 1.4.2 (build 6205) and have found that some functions perform inconsistently between Mac, Windows and Linux versions of PhotoScan.

For example, converting the chunk.crs via the GUI takes all of a fraction of a second on Mac/Windows, on my linux test bench however it takes between 5-10 seconds for a small project with <500 images. Running python scripts that use any of the CoordinateSystem transform methods or update camera/marker reference locations also run an order of magnitude slower on Linux compared to Mac/Windows.

Any ideas what could be causing this?

The Linux machine's specs are:

Agisoft PhotoScan Professional Version: 1.4.2 build 6205 (64 bit)
Platform: Linux
CPU: Intel(R) Xeon(R)
CPU family: 6 model: 85
RAM: 137.5 GB
OpenGL Vendor: VMware, Inc.
OpenGL Renderer: llvmpipe (LLVM 5.0, 256 bits)
OpenGL Version: 3.0 Mesa 17.2.8
Maximum Texture Size: 8192
Quad Buffered Stereo: not enabled
ARB_vertex_buffer_object: supported
ARB_texture_non_power_of_two: supported

Mac machine specs:

Platform: Mac OS
CPU: Intel(R) Core(TM) i7-4980HQ CPU @ 2.80GHz (laptop)
CPU family: 6 model: 70
RAM: 16.0 GB

Project used for testing in both was identical, reproducible in other project files as well.

Cheers,
