[feature] display wireframe of 3D model

[koebel]

For "power users" it would also be nice to give the option to show only wireframe without texture. Not sure if the current framework supports this? Maybe there is no interest in this by the average user, I guess only by those who actually work with 3D files

User Story

As a user
I want to see the wireframe of my 3D model
so that I can check the quality of the object

Acceptance Criteria

• display wireframe of 3D objects only (no texture) if option is activated
