VTKRemoteRendering¶

MLModule¶

author	`MeVis Medical Solutions AG`
package	`MeVisLab/VTK`
dll	`MLVTKRemoteRendering`
definition	MLVTKRemoteRendering.def
see also	`RemoteRendering`
keywords	`offscreen`

Purpose¶

The VTKRemoteRendering module allows to render a VTK visualization (represented as a vtkRenderer) using the MeVisLab remote rendering protocol.

In addition to the single vtkRenderer input, the module is also scriptable to:

access the render window and interactor
set the interactor style
add multiple renderers

To access the scripting API, just do:

API = ctx.object()

e.g. to add a renderer dynamically:

import vtk

ren = vtk.vtkRenderer()
ctx.object().GetRenderWindow().AddRenderer(ren)

Note: VTK cursor shapes are currently not supported, since vtkRenderWindow.SetCurrentCursor() seems to be used seldomly. If you require VTK cursors, please send a feature request.

Input Fields¶

inputVtkRenderer¶

name: inputVtkRenderer, type: VTKObjectWrapper(MLBase)¶: A vtkRenderer is expected.

Output Fields¶

output¶

name: output, type: RemoteRendering(MLBase)¶: The remote rendering base object.

For accessing this object via scripting, see the Scripting Reference: MLRemoteRenderingWrapper.

Visible Fields¶

Enable Multi Sampling¶

name: enableMultiSampling, type: Bool, default: FALSE¶: Enable the usage of a MSAA buffer.

Multi Sampling¶

name: multiSampling, type: Integer, default: 16¶: Defines the multi sampling for MSAA buffers.

Intercept double-clicks¶

name: interceptDoubleClicks, type: Bool, default: FALSE¶: Defines if double clicks are to be intercepted.
