Problem with compute_scalar_ambient_occlusion_gpu()

[Asma BRZ]

Hello, I have installed pymeshlab 2013.12. Here is a sample code that I have tried:
import pymeshlab ms = pymeshlab.MeshSet() ms.load_new_mesh("object1.ply') ms.compute_scalar_ambient_occlusion_gpu()

The function compute_scalar_ambient_occlusion_gpu gives Abandon (core dumped)

ps: I have tested different parameters of the functions and I got always the same error. Also, the other functions of pymeshlab work well. I only struggle with compute_scalar_ambient_occlusion_gpu.

Any help ?

Thank you

The gpu version, as it says the filter name, needs an environment where an opengl context can be created and executed. It may fail when this is not possible.
Anyway, in the latest version of pymeshlab there is an alternative to the gpu ambient occlusion (https://pymeshlab.readthedocs.io/en/latest/filter_list.html#compute_scalar_ambient_occlusion) that does work on cpu.
