Hi, Im working now for converting SharpDX project to OpenTK project. Im very newbie on OpenGL, and I have question for data transfering to Buffer.
In SharpDX, there is DataStream class for Buffer and It provides Write() method for write data to buffer stream.
I have quite big mesh data (over 200000 vertices), so I want to save my memory. But in OpenTK, it has only BufferData method and it needs original data array. I checked MapBuffer, but it returns only IntPtr and needs Unsafe oprtions.
Is there any method for creating buffer without data array, I mean like stream writing method without Unsafe?
