Thyandyr's voxel engine

[Thyandyr]

I think next I will work on moving the code that generates the vertex and indices arrays, from TChunk to TChunkManager. The latter has easy access to surrounding chunks so I can easier do some culling when drawing at the edge of the chunk. I thought at the same time I would also optimize the attribute data. https://www.khronos.org/opengl/wiki/...ttribute_sizes Not sure how to 'cheat' and insert four bytes instead of single, and how get 'use' them as bytes instead os a single in the shaders.




Also, is there a better way to get undefined entry from TDictionary? Feels kind-a odd, that part getting a key/id from ListLoad

procedure TChunkManager.ListLoadChunksProcess(const Steps: Cardinal);
var
  I: Integer;
  aID: String;
  C: TChunk;
begin
  for I := 1 to Steps do
    begin
      aID := '';


      if ListLoad.Count > 0 then        // If we have entries in the ListLoad
        for aID in ListLoad.Keys do     // Get one of them
          break;


      if aID <> '' then                 // If we do have Chunk to load
        begin
          ListLoad.Remove(aID);         // Remove the Chunk ID from ListLoad
          C := ChunkLoadCreate(aID);    // Load Chunk from disk or create it
          ListLoaded.Add(C.ID, C);      // Add to list of loaded chunks
        end
      else                              // Break out, nothing to process
        break;
    end;
end;
