WebGL vendor [显卡]指纹

一、WebGL vendor：(厂商)

Google Inc. (NVIDIA)

c++定义在

third_party\angle\src\libANGLE\Display.cpp

格式化Google Inc.字符在Display::initVendorString()函数里面，可以在此修改值。

cpp 复制代码

void Display::initVendorString()
{
    mVendorString                = "Google Inc.";
    std::string vendorStringImpl = mImplementation->getVendorString();
    if (!vendorStringImpl.empty())
    {
        mVendorString += " (" + vendorStringImpl + ")";
    }
}

cpp 复制代码

const std::string &Display::getVendorString() const
{
    return mVendorString;
}

二、WebGL renderer：(渲染)

ANGLE (NVIDIA, NVIDIA GeForce RTX 3060 (0x00002504) Direct3D11 vs_5_0 ps_5_0, D3D11)

src\ui\gl\gl_implementation.cc里面

const char* renderer_str =

reinterpret_cast<const char*>(api->glGetStringFn(GL_RENDERER));定义了获取

ANGLE (NVIDIA, NVIDIA GeForce RTX 3060 (0x00002504) Direct3D11 vs_5_0 ps_5_0, D3D11)

cpp 复制代码

bool WillUseGLGetStringForExtensions(GLApi* api) {
  const char* version_str =
      reinterpret_cast<const char*>(api->glGetStringFn(GL_VERSION));
  const char* renderer_str =
      reinterpret_cast<const char*>(api->glGetStringFn(GL_RENDERER));
  gfx::ExtensionSet extensions;
  GLVersionInfo version_info(version_str, renderer_str, extensions);
  return version_info.is_es || version_info.major_version < 3;
}

可以在此处修改。

const char* renderer_str =

reinterpret_cast<const char*>(api->glGetStringFn(GL_RENDERER));函数实现在

主要修改指纹点介绍完毕，仅供学习参考。
