also add a game pause/restart/save/exit dialog and a general exit dialog

• tile-based (9x base tile, base tile consists of two instances of the sand.gltf, tiles mirrored to match meshes)
  • alternatively, a single tile could be one gltf file (might be easier to place cactuses)
• real sky box (moves with position moves with cam position)
• directional light 0 and directional light 1 move according to cam position

application/lucre/scenes/mainScene.cpp

To recreate all you need to do is close the game with the menu enabled.
Also when the menu is open, the volcano stops but I don't know if that is intentional.

SW dev cycle-wrap for: json scene loading, fbx file support, scene graph refactor, material system refactor, and instancing

remaining sw changes / bug fixes:

• fix shadows for instancing
• instancing: transform component with model/normal matrix in instance buffer
• instancing: ECS model access for all instances for skeletal animation

video:

• animation for copying 3D file scene graph into main scene graph: Mantar finished
• topics:
  ~~json scene loading, scene graph, ~~
  gltf, fbx,
  material system, instancing,
  thread pool/transfer queue pool and KTX
• one part (8 topics) or two parts (4/4) or four parts (2/2/2/2)? --> 4 parts
• script, video editing, voice over

Terms:

• chunk: larger area corresponding to a height map (maybe 25m x 25m or 100m x 100m)
• cell: node of quadtree, a result of dividing a chunk
• patch: input primitive for tesselation control shader, usually triangle
