WebGL: INVALID_VALUE: texImage2D: invalid internalformat - depthTexture in webgl2 

const depthTextures = gl => {
  const depthTexture = gl.createTexture();
  const depthTextureSize = 512;
  gl.bindTexture(gl.TEXTURE_2D, depthTexture);
  gl.texImage2D(gl.TEXTURE_2D, // target
  0, // mip level
  gl.DEPTH_COMPONENT, // internal format
  depthTextureSize, // width
  depthTextureSize, // height
  0, // border
  gl.DEPTH_COMPONENT, // format
  gl.UNSIGNED_INT, // type
  null); // data

  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.NEAREST);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.NEAREST);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_WRAP_S, gl.CLAMP_TO_EDGE);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_WRAP_T, gl.CLAMP_TO_EDGE);
  const depthFramebuffer = gl.createFramebuffer();
  gl.bindFramebuffer(gl.FRAMEBUFFER, depthFramebuffer);
  gl.framebufferTexture2D(gl.FRAMEBUFFER, // target
  gl.DEPTH_ATTACHMENT, // attachment point
  gl.TEXTURE_2D, // texture target
  depthTexture, // texture
  0); // mip level
  // create a color texture of the same size as the depth texture
  // see article why this is needed_

  const unusedTexture = gl.createTexture();
  gl.bindTexture(gl.TEXTURE_2D, unusedTexture);
  gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, depthTextureSize, depthTextureSize, 0, gl.RGBA, gl.UNSIGNED_BYTE, null);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.NEAREST);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.NEAREST);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_WRAP_S, gl.CLAMP_TO_EDGE);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_WRAP_T, gl.CLAMP_TO_EDGE); // attach it to the framebuffer

  gl.framebufferTexture2D(gl.FRAMEBUFFER, // target
  gl.COLOR_ATTACHMENT0, // attachment point
  gl.TEXTURE_2D, // texture target
  unusedTexture, // texture
  0); // mip level

  return [depthFramebuffer, unusedTexture];
};

I found

Note: This extension is only available to WebGL1 contexts. In WebGL2, the functionality of this extension is available on the WebGL2 context by default. The constant in WebGL2 is gl.UNSIGNED_INT_24_8.

I change DEPTH_COMPONENT with RGBA but still no attaced framebuffer...

In other combination i get :

gl.texImage2D(
    gl.TEXTURE_2D,      // target
    0,                  // mip level
    gl.RGBA, // internal format
    depthTextureSize,   // width
    depthTextureSize,   // height
    0,                  // border
    gl.RGBA, // format
    gl.UNSIGNED_INT_24_8,    // type
    null);              // data

 GL_INVALID_OPERATION: Invalid combination of format, type and internalFormat.

 GL_INVALID_OPERATION: Only array uniforms may have count > 1.

Any suggestion ?

This is source which i wanna implement in my own already exist glmatrix project...

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
