JavaScript => public function GetNativeTexturePtr(): IntPtr;
C# => public IntPtr GetNativeTexturePtr();

Description 描述

Retrieve native ('hardware') pointer to a texture.

检索纹理的本地（硬件）指针。

Use this function to retrieve a pointer/handle corresponding to a particular texture as it is represented on the native graphics device level. This can be used to enable texture manipulation from native code plugins.

使用该函数来检索特定纹理的指针或句柄，表示在本机图形设备的级别。这用来从本机代码插件来启用纹理操作。

On Direct3D-like devices this returns a pointer to the base texture type (IDirect3DBaseTexture9 on D3D9, ID3D11Resource on D3D11). On OpenGL-like devices the GL texture “name” is returned; cast the pointer to integer type to get it. On Metal, the id<MTLTexture> pointer is returned. On platforms that do not support native code plugins, this function always returns NULL.

像在Direct3D设备返回基本纹理类型的指针（IDirect3DBaseTexture9 on D3D9, ID3D11Resource on D3D11）；像在OpenGL设备返回GL纹理名称，强制转换整数类型来获取它；在Metal，返回id<MTLTexture>指针。在不支持本地代码插件的平台，该函数总是返回NULL。

Note that calling this function when using multi-threaded rendering will synchronize with the rendering thread (a slow operation), so best practice is to set up needed texture pointers only at initialization time.

注意，当使用多线程调用这个函数，将于渲染线程同步（操作缓慢），所以最好的做法是在初始化时设置所需的纹理指针。

IntPtr用于表示指针或句柄的平台特定类型，它们用于本机资源，如窗口句柄。
