We need to revisit camera animation in ParaView. The current UI is quite clumsy and cumbersome to use. Here are some of the limitations of the current one:
- "follow path" uses a fixed up direction for the whole path. To overcome this issue, folks split the path, but then change in the view up direction is abrupt between paths.
- "follow path" doesnt offer mechanism to use current camera parameters like "interpolate camera locations"
- setting up parameters for multiple paths for "follow path" is insanely complex esp when trying to keep end points consistent.
- "Interpolate camera locations" mode doesn't offer linear interpolation mode. The current interpolation has tendency to overshoot.
