[shared-arena] by [@0x5eb] is a thread-safe & efficient memory pool.

Memory pools are usefull for speeding up dynamic (de)allocation

of large amounts of data of the same size.

shared-arena provides three memory pools with different trade-offs:


The crate uses unsafe in a few places,

but the code is covered by the miri interpreter, valgrind and 3 sanitizers

(address, leak and memory) [on each commit][shared-arena-ga].

[density-mesh] by [@PsichiX] is an image density/height map to mesh generator.

It consists of two crates:

- density-mesh-core - generates mesh from density map.

- density-mesh-image - generates density map from image.

Typical use case would be to use two of them to create mesh from images

but in case you have your own image handler, you can stick to the core module

and produce density maps by yourself.

There's also a [CLI tool][density-mesh-cli].
