Core Techniques
Ordered Index
ordered by chunk layer and offset of the chunk in the file, use a separate ID to indicate the order
Index Linearization
linearize the ordered index to separate linear index streams
Chunk Lookup and Chunk Cache
find all the effective chunks concerning frame n, and cache them, for they may still be effective to the next frame
Key Framing
generating of inter-mediate frames according to a key frame pair
Zlib Compression
use zlib to compress the pos_and_color of compressed chunks
Utility Techniques
File Cache
cache a piece of the file to speed up the I/O
Frame Cache
cache a sequence of generated TCAS frames to improve the overall performance
Obsolete Techniques
Threadpooling
use a threadpool to generate TCAS frames in parallels
Mapping of File
map the whole file into memory
