Javascript WebGL：INVALID_VALUE：texImage2D：无效的内部格式 webgl2 中的 depthTexture

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];
};

我发现

注意:此扩展仅适用于WebGL1上下文.在WebGL2中， 此扩展的功能在WebGL2上下文中可用 默认情况下.WebGL2中的常量是gl.UNSIGNED_INT_24_8.

我将DEPTH_COMPONENT更改为RGBA，但仍然没有附加的帧缓冲区...

在其他组合中，我得到:

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.

有什么建议吗？

这是源码，我想在我自己已经存在的GLARIX项目中实现…
