Advice for displaying time dependent image data

Web
1

I am looking for advice to render time dependent image volume data through vtk-js.

My initial intent was to load a vti file with multi-component point data representing the time vector. However, it doesn’t appear that I can use the Extract Component" filter in vtk-js which would take advantage of this.

Thus, would my best option be to load multiple vti files and show/hide actors (based on e.g. a slider position)?

Thanks for the advice.

Correct, there currently is no ExtractComponent filter. What you suggest is a reasonable approach. If you want to avoid dumping many actors into your scene, you can also have one actor, and simply change the input data via volumeMapper.setInputData(image)
