Sorry I’m new to threejs, and just need guide on what topics should I learn before making this kind of feature below. So basically, there are lots of items or cargo inside a container where we can also select loading from the dropdown so we see how the items will be loaded. Please see the video link below for reference.
I recommend you start here and take a few tutorials and courses. As your abilities improve through the courses, the solutions to your task will start becoming more and more apparent.
@marquizzo Thanks for your response. I appreciate it
