This greatly reduce the number of std::list generated by caching the result, which is always constant for each radius selected.
In the callgrind map, you will see original:
* 3.3M calls to std::list for 9700 calls to getFacePositions
In the modified version, you will see:
* 3.3K calls to std::list for 6900 call to getFacePositions
Callgrind map is here: #2321
it's a huge performance improvement to l_find_node_near
Change must_reflow to a deque
Add overload for MapBlock::raiseModified that takes a const char*. This is a speed improvement.
Comment out unused variable
Optimisations to block offset calculations
- Don't create and cache an extruded mesh for every (non-node) item.
Instead use a single one per image resolution.
- For cubic nodes reuse a single wield mesh too
- Improve lighting of the wielded item
- Increase far value of wield mesh scene camera, fixes#1770
- Also includes some minor refactorings of Camera and GenericCAO.
