EmaMaker e4c6eb50f3 Merge branch 'main' into multithread-refactor 2023-10-04 14:55:47 +02:00
EmaMaker 9b5939d256 renderer: do not send empty meshes to the gpu only at creation 
I feel never sending empty meshes to the GPU is the cause of the bug causing floating quads near
chunk borders when a block is placed and then destroyed.
When destroying a block in a chunk, if nearby empty chunk meshes are not updated, the old mesh is
kept, which includes a quad at the border

EmaMaker 7786d4f04d renderer: use ChunkMeshData from rendering thread 
This system decouples the Secondary threads from the Render thread. Once a chunk is meshed, only the mesh data is sent to the rendering thread, which does not use any direct reference to the chunk itself

EmaMaker 88abf21502 multithread: refactor update thread, communication between mesh/gen/upd threads 
- Use parallel_for to iterate over all the stored chunks
- Only push a chunk to a queue if it is not already present, using chunk state bitfield (solves
	memory leak, continously adding new elements to a queue)
- Properly delete an element from chunks concurrent_hash_map using accessor, then free the memory
(solves memory leak: not being able to delete old elements and always adding new ones)

Breaks:

- Rendering (will be properly refactored in a future commit)
- Block picking (will be refactored in a future commit)
