Goals

  • Render 2D charts using OpenGL/VTK
  • Scalable to large data sets
  • Simple, flexible API
  • Enable server side rendering of charts with VTK compositing

Open Questions

  • Alternate backend to produce publication quality output?
  • Possibility to extend the API to 3D charts in the future?
  • Maybe real-time charting? (just-in-time visualization of data sets)

Further Details on API

Please see VTK/Charts/API API for a discussion about the API. There is also more detail about the VTK/Charts/2DAPI "2D API" and the VTK/Charts/ChartAPI "chart API" along with proposed class relationships.
