2022.X Release plan

It has been suggested that Post FlightGear 2020.2 LTS changes be merged into this article or section.

This page sets out what is planned for the LTS following 2020.3. For ease of reference, this is referred to as 2022.X, though there is no guarantee that all features listed will be in that release, or that it will be released in 2022!

Dependencies

See also Post_FlightGear_2020.2_LTS_changes#Code_clean-ups_and_changes.

• Make CMake 3.6 the minimum required version: this will allow simplifying a bunch of compatibility logic in the build files while fixing OSGText Issues and broken event handling in CompositeViewer Support mode (There were issues with some Linux distributions only having OSG 3.4 in their repos, but we will need to compile OSG with custom flags anyway for the core profile, so it should be fine. )

Rendering

• OpenGL Core Profile
  • Canvas rendering using NanoVG (see existing OSG integration via osgnanovg)
• Requires graphics cards to support shaders
• Compositor framework

Simulator Features

• HUD based on Canvas
• 2D panels based on Canvas

Scenery

• World Scenery 3.0
  • Regular terrain mesh with landclass texture draped on top, using Virtual Planet Builder
  • Airports inserted into terrain at runtime so they can be updated without modifying the terrain mesh
  • Line features inserted into terrain at runtime. E.g. roads, railways, rivers
• STG Support:
  • Mesh radius (improves LOD)
  • TREE_LIST
  • LIGHT_LIST

• osm2city must have:
  • Mesh radius for LOD
  • LIGHT_LIST
  • TREE_LIST
  • WS3.0 features (e.g. roads, line features)

• osm2city might have depending on availability of helping hands:
  • New building texturing
  • Aerialways extended to other types than ski lifts
  • Street lights - related to LIGHT_LIST
  • Sports pitches
