Select area and access it

I’m really new in THREEJS. I want to select an area on an object(for example a wheel of a car) and store it in some way and highlight it in the future. How can I do this?

Welcome to the forum.

It seems like you are seriously underestimating what would be involved in what you’re asking for. No offence intended, all of us started ignorant.

There is an example program available which shows how objects in a three.js scene can be selected. Which falls, imo, already into the “advanced” category.

If you click the circular “<>” button in the lower-right corner of the example programs window, you’ll be taken to the source code of that program.

A good way to learn is, to take running examples and changing them a little at a time, until you get a feeling for which changes have which effect.

You may want to start at the beginning, though:

May the force be with you.

Really thanks to you :slight_smile:
I’m looking for a good resource to learn 3D basic concepts. Can you help me to find one?

The ThreeJS examples, source code, and API documentation are great for this! I’ve used them to learn (from zero knowledge of javascript and 3d modeling). I built a program to pull live building information and render the buildings in 3-D.

I agree with that.
There you will find many examples of the community.

If you don’t mind using React this can be done in a couple of lines now

It’s different to actually understanding how to do it, of course. But that’s ok when starting out - and maybe forever. How many people using three.js understand the renderer code, for example?
