Detailed Description

The BMLog is an interface for storing undo/redo steps as a BMesh is modified. It only stores changes to the BMesh, not full copies.

Currently it supports the following types of changes:

Adding and removing vertices
Adding and removing faces
Moving vertices
Setting vertex paint-mask values
Setting vertex hflags

If the log entry list is empty, or if the current log entry is the last entry, the new entry is simply appended to the end.

Finally, the new entry is set as the current log entry.

Uses entry->log as the log. If the log is NULL, the entry will be freed but not removed from any list, nor shall its IDs be released.

Warning: This operation is only valid on the first and last entries in the log. Deleting from the middle will assert.

◆ BM_log_vert_before_modified()

void BM_log_vert_before_modified	(	BMLog *	log,
		BMVert *	v,
		int	cd_vert_mask_offset )

Log a vertex before it is modified.

Before modifying vertex coordinates, masks, or hflags, call this function to log its current values. This is better than logging after the coordinates have been modified, because only those vertices that are modified need to have their original values stored.

Handles two separate cases:

If the vertex was added in the current log entry, update the vertex in the map of added vertices.

If the vertex already existed prior to the current log entry, a separate key/value map of modified vertices is used (using the vertex's ID as the key). The values stored in that case are the vertex's original state so that an undo can restore the previous state.

On undo, the current vertex state will be swapped with the stored state so that a subsequent redo operation will restore the newer vertex state.
