For my graduation project, I am building an AR app that would recognise paintings and showcase a 3D character that would trigger a text that gives you more details about it. However, it should also give you details about a specific detail in the photo (a certain building, a necklace, a tree...etc)
I am stuck in implementing the following task: I want the user to be able to know specific information about the painting provided, for example if the painting is about a lady and she is wearing a necklace (I cropped and added the necklace to the database), then I want to write a script that once it recognises the necklace, it triggers a window above the 3D character, that I should use as a virtual tour guide, to illustrate the origin of this necklace.
To sum up, how can I implement a script that would enable me to do that. If you have any documentations of something similar, that would be of a great help. Thank you so much for your time!
