QUESTION
As the title states, I am using es6 classes, but because they are all not modules apart from the main.js file, it makes it difficult to use API's because I cannot make use of import modules.
I used the code from this link's answer: How to add in Three.js PointerLockControl? and pasted the code into a js file, calling it up in my HTML, but I get an error stating:
Uncaught ReferenceError: PointerLockControls is not defined
It is not picking up the class when I reference it. I tried to link it to the GitHub raw code, and it didn't pick it up either.
This is my index.html code (only one line referencing the GitHub raw code):
...ANSWER
Answered 2021-May-26 at 18:31I changed all my es6 classes into es6 modules, and used import. I don't think there was a solution for this with cdn or raw git scripts.

In ThreeJS, it is possible to add more than one material to an Object3D/Mesh according to its documentation. We can use a single Material
or use an array of Material

I am trying to add a 3D object to the scene.

Answered 2021-May-21 at 23:10It is telling you that you cannot invoked GLTFLoader
without 'new' at new GLTFLoader
If you look at the doc you linked in the code exemple they use
const loader = new GLTFLoader();
before doing anything with it.
You must instance GLTFLoader

QUESTION
I'm am currently trying to draw shapes or at least the equivalent of geometry
in ThreeJS r128
with exclusively with shaders.
The common way to draw stuff on the screen with this library consist of creating a mesh
with a geometry
(here is the boilerplate code for project creation) associated to it. After the creation of that object, we can apply a shader to this new component via the ShaderMaterial class.
However, I can't find how to render the shader on the scene rather than on an object. With OpenGL Shading Language (GLSL), we can actually draw shapes on the screen without having vertices. That's what I am aiming for, but it seems that I am tangled up in this rendering system.
Is it even possible to render only with the shaders in ThreeJS ?
For testing, here is a function to create a filled circle with shader:

I'm pretty new to threeJS and i wanted ton have the shadow of the torus to be casted on the PlaneGeometry behind it.
I tried to play with .castShadow
& .receiveShadow
but with no result
Could you explain what I did wrong ?
...ANSWER
Answered 2021-May-12 at 13:33You have used MeshBasicMaterial
for your plane mesh which is a unlit material. So it does not receive shadpws. Using a lit material like MeshStandardMaterial
solves the issue.

I'm trying to find the names of all classes that either meet in room R128 or have five or more students enrolled in these two tables called 'enroll' and 'class'. I can find the two parts of this question individually, but I don't understand how I can find them both in one query.

I am working to copy data based on a value from one open workbook to another. I have a list of values in the destination workbook sheet and have a loop to find the values in another open source workbook sheet. The code works fine, however, with the way i have it set up i don't have any more room to add specialpaste or numberformat functions for the destination workbook. I know there has to be a simple way to condense my code, just having trouble figuring that out.
