### Question 1
|
2022-02-12 00:28:54 +01:00
|
|
|
|
|
|
|
|
This is a packing problem, as described on [Wikipedia][1].
|
|
|
|
|
Since this is NP-hard, we know the "exact" solution might be unreachable but we
|
|
|
|
|
could find a solution that is good enough for our needs.

|
## PNG support
|
|
|
|
|
|
|
|
|
|
I chose to support PNG files through the stb files:
|
|
|
|
|
[github.com/nothings/stb](https://github.com/nothings/stb).
|
|
|
|
|
I could have implemented basic image support with the PNM format but I think it
|
|
|
|
|
is nicer to support common image formats with a simple library.
|
|
|
|
|
|
|
|
|
|
stb also implements a 2D rectangle packer:
|
|
|
|
|
[stb_rect_pack.h](https://github.com/nothings/stb/blob/master/stb_rect_pack.h)
|
|
|
|
|
I added this file in the project in order to compare my implementation to
|
|
|
|
|
another one.
|
|
|
|
|
|
|
|
|
|
## 3rd party libraries
|
|
|
|
|
|
|
|
|
|
I use 2 external libraries for better visualization:
|
|
|
|
|
- stb files (for PNG)
|
|
|
|
|
- raylib (for GUI)
|
|
|
|
|
|
|
|
|
|
I don't rely on them for the algorithm implementation and the core of the
|
|
|
|
|
exercise doesn't rely on external libraries.

|
To avoid name collision, I created my own namespace `freling`.
