To be able to understand the shadow behavior of the lights a bit better this video introduces more objects to the scene. To create a grid of boxes, you will make use of the three.js Group object, which is a nongeometric object used for organizing other objects together. You can think of it as an HTML div element that you might create for the sole purpose of wrapping other objects if you have a web development background. Or you can think of it corresponding to a folder in Photoshop or a null object in other 3D software. It serves the purpose of containing other objects.
- [Instructor] In this video, I will be creating…a scene with more objects before we start…looking at other light types.…That will help us understand the differences…between light types a little bit better.…In this scene, instead of having a single box,…I will have a grid of boxes.…To save us some time, I already built…a function called getBoxGrid…that allows us to create this grid.…You can find it in exercise files for this video.…Let me walk you through how I built this function.…Here, I have simply two nested for loops…that creates a desired amount of boxes…with the given separation value.…
The only thing that is new here…is the usage of the Three.js Group object.…A Group is a non-geometric object…used for organizing other objects together.…You can think of it as an HTML div element…that you might create for the sole purpose…of wrapping other objects if you have…a web development background…or you can think of it corresponding to a folder…in Photoshop or a null object in other 3D software.…It serves the purpose of containing other objects.…
