            Difficulty incorporating pointer lock controls API in three.js using es6 classes that are not modules
            Asked 2021-Jun-04 at 00:51

            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):

            I 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.

            It 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.

            Render a shader without having to add a Geometry to the scene in ThreeJS
            Asked 2021-May-23 at 07:22

            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:

            You 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.

            You want to match a case insensitive character group containing letters and digits, repeated 10 to 13 times. if you allow underscores _ then you could use ^\w{10,13}$. as presented the pattern you want is ^[a-z\d]{10,13}$ with a case insensitive flag. or ^[a-zA-Z0-9]{10,13}$ if you want to be verbose.

            Support

            This library requires a C99 compliant compiler, however it could be made to compile with a pre-C99 compiler that supports 64-bit integers. The only two changes needed are providing suitable typedefs for int64_t and uint64_t and replacing the ull integer suffix with the appropriate one for your compiler. On x86 and x64 targets, Intel intrinsics are used for speed. If your compiler does not support these intrinsics, you can add #define R128_STDC_ONLY in your implementation file before including r128.h. The only C runtime library functionality used by this library is <assert.h>. This can be avoided by defining an R128_ASSERT macro in your implementation file. Since this library uses 64-bit arithmetic, this may implicitly add a runtime library dependency on 32-bit platforms. C constructors and operator overloads are provided for C files that include r128.h. All C-isms are guarded by conditional compilation blocks, and all C functions are marked static inline, so r128.h can be included in both C and C source files. The source file that defines R128_IMPLEMENTATION can be either C or C.
