TTK now comes with a whole deferred rendering framework as described here: [2010.03936] Cinema Darkroom: A Deferred Rendering Framework for Large-Scale Datasets
Many of these filters process vtkImageData objects and produce actual rgba color scalar arrays. To look at the colors directly one always has to disable the “Map Scalars” display property in ParaView. It would be great if one could specify this in the XML file just like the preferred representation type.
These filters can also process lists of images that are represented as a vtkMultiBlockDataSet where each block is an image. Although PV offers the slice representation in the drop down menu for such a vtkMultiBlockDataSet, choosing that option results in the following error:
vtkPVDataRepresentationPipeline (0x558cdf17b140): Can not execute simple algorithm without output ports
So the only way to currently inspect the image set is to select the surface representation which produces a lot of geometry for a set of full HD images.
So does anyone know if these issues would just require a quick fix or if this is something more substantial? If you point me in the right direction I can also try to fix this myself and open a PR.
