◆ ARRAY_CHUNK_NUM_MIN

#define ARRAY_CHUNK_NUM_MIN 256

Definition at line 72 of file editmesh_undo.cc.

Referenced by array_chunk_size_calc().

◆ ARRAY_CHUNK_SIZE_IN_BYTES

#define ARRAY_CHUNK_SIZE_IN_BYTES 65536

This used to be much smaller (256), but this caused too much overhead when selection moved to boolean arrays. Especially with high-poly meshes where managing a large number of small chunks could be slow, blocking user interactivity. Use a larger value (in bytes) which calculates the chunk size using array_chunk_size_calc. See: #105046 & #105205.

◆ USE_ARRAY_STORE

#define USE_ARRAY_STORE

Definition at line 53 of file editmesh_undo.cc.

◆ USE_ARRAY_STORE_RLE

#define USE_ARRAY_STORE_RLE

Use run length encoding for boolean custom-data.

Avoid poor performance caused by boolean arrays not having enough uniqueness to efficiently de-duplicate, see: #136737.

NOTE(@ideasman42): This has the down-side that creating undo steps needs to encode data before comparing it with the previous state (when creating each undo step). Adding additional work even when nothing change.

Since there is overhead for RLE encoding this is only used on boolean array, typically used for storing selection/hidden state as well as edge flags. The encoding has also been optimized for performance instead of "compression" which would pack bits into the smallest possible space.

In practice, arrays of 32 million booleans (on an AMD TRX 3990X):

~0.11 seconds for random data.
~0.0025 seconds uniform arrays. ... so the tradeoff seems reasonable.

There is also the benefit of reduced memory use, although that isn't the goal.

Create an array of UndoMesh from objects.

where each element in the resulting array is the most recently created undo-mesh for the object's mesh. When no undo-mesh can be found that array index is nullptr.

This is used for de-duplicating memory between undo steps, failure to find the undo step will store a full duplicate in memory. define DEBUG_PRINT to check memory is de-duplicating as expected.
