Detailed Description

A specialized GribRecordSet that represents temporally interpolated weather data with isobar rendering optimizations.

While GribRecordSet simply holds meteorological parameters at a point in time, GribTimelineRecordSet provides:

  1. Temporally interpolated records between two time points.
  2. Cached calculations for visualization (e.g., isobars).

This class is used when:

  • Displaying weather conditions between available GRIB timestamps.
  • Animating weather evolution over time.
  • Rendering isobars, isotherms, and other derived visualizations.
See also
GribRecordSet for basic parameter storage.
GetTimeLineRecordSet() for how interpolation is performed.

Constructor & Destructor Documentation

◆ GribTimelineRecordSet()

GribTimelineRecordSet::GribTimelineRecordSet ( unsigned int  cnt)

Creates a timeline record set containing temporally interpolated GRIB records.

Timeline record sets store cached data like isobar calculations to optimize rendering performance during animation playback.

Parameters
cntSource GRIB file identifier used to trace record origins

Member Data Documentation

◆ m_IsobarArray

wxArrayPtrVoid* GribTimelineRecordSet::m_IsobarArray[Idx_COUNT]

Array of cached isobar calculations for each data type (wind, pressure, etc).

Each element is a pointer to a wxArrayPtrVoid containing IsoLine objects. Used to speed up rendering by avoiding recalculation of isobars.
