Detailed Description
This node implements a 2d texture which is updated every time the node is traversed.GL_TEXTURE_2D_Sink takes the context of it's first registered parent node. The node can be used to integrate an OpenVideo sink into another programm. therefore it implements a way to lock and unlock the texture it updates.
Supported Pixel Formats:
- : R8G8B8
- : B8G8R8
- : R8G8B8X8
- : B8G8R8X8
- : L8
