◆ CreateBufferFromGLHandle()

virtual void Diligent::IRenderDeviceGL::CreateBufferFromGLHandle	(	Uint32	GLHandle,
		const BufferDesc &	BuffDesc,
		IBuffer **	ppBuffer
	)

pure virtual

Creates a buffer from OpenGL handle.

Parameters

[in]	GLHandle	- OpenGL buffer handle
[in]	BuffDesc	- Buffer description. The engine can automatically recover buffer size, but the rest of the fields need to be set by the client.
[out]	ppBuffer	- Address of the memory location where the pointer to the texture interface will be stored. The function calls AddRef(), so that the new object will contain one refernce.

Note: Diligent engine buffer object does not take ownership of the GL resource, and the application must not destroy it while it is in use by the engine.

◆ CreateTextureFromGLHandle()

virtual void Diligent::IRenderDeviceGL::CreateTextureFromGLHandle	(	Uint32	GLHandle,
		const TextureDesc &	TexDesc,
		ITexture **	ppTexture
	)
