Help with a basic 3D object viewing app

How to make a basic app that will load a 3D bottle in a window and then you can rotate it / and open / close it’s top - with assigned keys or with mouse clicks (something like in the 3D objects sharing websites were you can visualize 3D objects?

First you need to understand that the model of the bottle would need to be designed to have a top that unscrewed. I’ll go out on limb without searching and say there will be bottles available to buy from the asset store or turbosquid or other purveyor of 3 D items with animations that unscrew the top.

Next really look at some of the tutorials. To zoom in all you need to is move the bottle closer to the camera or vise versa. To rotate you just rotate the transform.

So what you really need is some basic understanding of transforms.

First try the tutorials.

When I first learnt, I found these YouTube tutorials very useful and it starts at opening the software and finishes at making animations.
