gl-text | Render text with WebGL | Graphics library

I know there are a lot of resources on this, but none of them have worked for me.
Some are: webgl readpixels is always returning 0,0,0,0,
and this one: https://stackoverflow.com/questions/44869599/readpixels-from-webgl-canvas\ as well as this one: Read pixels from a WebGL texture
but none of them have been either helpful or successful.

The goal: Render an offscreen canvas with a WebGL shader, then use that as a texture in a separate WebGL shader.

Notes:

• For these WebGL shaders, I'm using a generic vertex shader used for pixel shaders, specifically, a raytracer/raymarcher. This is: attribute vec2 a_position; void main() { gl_Position = vec4(a_position.xy, 0.0, 1.0); }. This vertex shader is inputted two triangles that cover the screen, so basically the fragment shader is doing all the work.

Problem: In order to get the image data off of the offscreen canvas, I've tried these methods:

1. The WebGL gl.readPixels function

I would like to use wood.jpg as the background for an OpenGL program. I would like this program to also show the model basketball.obj as shown in the picture:

I've read several tutorials( Youtube channels sentdex, atibyte, The Cherno). I also tried the website learnopengl.com, opengl-tutorial.org, and codeloop.com. I've also used Udemy. None of these specifically show how to use a .jpg as a background for .obj models.

I can run code for multiple models that have been defined within the main code. I can also run code for multiple .obj files. But I have failed run code that can run both at the same time.

Can someone please help me? I can code in both OpenGL C++ and pyOpenGL for Python.

So far, the only success I have had in displaying the image wood.jpg as the background:

TL;DR: I've activated and bound textures to textureunits 1-4 and now I wish to use them within shaders without using a program specific uniform position. Is it possible to read data from textures using the "global" texture units?

I'm having a bit of a hard time understanding how to access textures in webgl. Here in this tutorial on textures it says "Texture units are a global array of references to textures.", and this sounds great. I've bound my textures using

I have written a function that creates an image from a font using Freetype2. My goal is to create an OpenGL-texture with all characters from the font. But first, I want to make sure the texture gets created properly, thus I store it as an image with stb_image_write for now. This is my progress so far:

As you can see, the glyphs are not aligned along the baseline, but along the top of the image. So I decided to introduce a variable called "yOffset", which describes the amount of pixels that each glyph has to be moved down to align them properly.

According to an answer in Render FreeType text with flipped ortho, difference between top and baseline of glyph, this offset can be calculated with

I'm trying to make 2D transform about webgl. There is no problem about rotation, and probably scale works good. On the other hands, translation is not working anyway. I suppose, I made a stupid mistake and I can't see that what i missed.

handlePressedDownKeys(translation), I passed array and when i pressed w, s, d, a, translation[0] or translation[1] will be increased or decreased. I didn't add this function but it works fine because when I pressed button, I can see matrice which on screen's 6. and 7. values was changing.

That's my code:

How can i read and store the javascript rendered HTML of a website using selenium in headless mode? I wrote this code, but the div tag i am interested in to store is not rendered, while if i run the same script in non headless mode i am able to get the tag.

I want to display text using the mentioned method in this article. Meanwhile I care about code to be generic.

In the article it mentions manually creating a buffer info which I call first method :

In the ARCore demo app Preview 2, I don't see the following line in the manifest:

So I've done a lot of research so far and haven't found even a hint of something that could cause this. I put htaccess in the tags since I thought that could technically do it.

The problem is this: I have a server to migrate. So I want to download all the files from the old server, and then reupload to the new server. What happens when I go to the online file manager and click compress and download is that a very important folder is missing from the zip (and judging by the counts there are others missing too).

I've also used Filezilla to recursively download the whole directory structure, but it also misses that folder. Even stranger is that Filezilla sees the folder and I can download it directly, but if I recursively download the folder just above it, it doesn't grab it. It's the same with the online file manager, it sees it too.

I even wrote my own c# program to do a basic directory listing and it doesn't see it. It uses an FtpWebRequest with Method set to WebRequestMethods.Ftp.ListDirectoryDetails.

So the problems persists on both server side functions as well as the client attempts through FTP protocols.

There is an .htaccess file specific to the folder in question but I can't see anything that might do this. (Included below)

Does anyone have any ideas? I'd be most grateful for any hint
