Detailed Description

VTK-m OpenGL Interoperability.

vtkm::interop defines the publicly accessible API for interoperability between vtkm and OpenGL.

Function Documentation

TransferToOpenGL() [1/2]

template<typename ValueType , typename StorageTag >

void vtkm::interop::TransferToOpenGL	(	const vtkm::cont::ArrayHandle< ValueType, StorageTag > &	handle,
		BufferState &	state
	)

Manages transferring an ArrayHandle to opengl .

TransferToOpenGL manages to transfer the contents of an ArrayHandle to OpenGL as efficiently as possible. Will use the given state to determine what buffer handle to use, and the type to bind the buffer handle too. If the type of buffer hasn't been determined the transfer will use deduceAndSetBufferType to do so. Lastly state also holds on to per backend resources that allow for efficient updating to open gl

This function keeps the buffer as the active buffer of the input type.

This function will throw exceptions if the transfer wasn't possible

TransferToOpenGL() [2/2]

template<typename ValueType , class StorageTag , class DeviceAdapterTag >

void vtkm::interop::TransferToOpenGL	(	const vtkm::cont::ArrayHandle< ValueType, StorageTag > &	handle,
		BufferState &	state,
		DeviceAdapterTag
	)
