Question

Display/aliasing problem with cross hatching

Hello, I am currently working on a 2.5D animation/slideshow presenting engravings made with the cross hatching technique.
The problem is that the hatches create visual artifacts that destroy the image (captures).
Switching the visuals to 2D reduces the effect but doesn't make it go away, and all of my scenes are 2.5D. 
Adding blur also reduces the problem without solving it and reducing the quality of the visuals...
Any idea/solution?  Thanks in advance.

You are getting Moiré patterns because of the style of the artwork. Thre are several ways to combat this problem. Here's a basic video that kind of explaines it:

Hello and thank you very much for your feedback.
Sorry for the reaction time but I am currently very busy with the project in question and for which we have taken another artistic direction.
Thank you for your answer all about, as a graphic designer and motion designer I know this optical illusion, but I was wondering if there was a solution that I did not know.
The video is extremely interesting but does not solve the problem, and I think it never really can be since the problem is not technical but physical.
It all depends on our eyes and the screen, the effect disappears and reappears depending on the ratios/format/screens/orientation of the gaze.
Just as we don't all see the same colors, we can never fight against the laws of physics.
Just so you know, this is a documentary about a monument that should have been made if a famous spike-shaped French monument hadn't stolen its place.
Good day
