# Bachelor Project Report
|
||
|
|
|
||
|
|
## Week 1
|
||
|
|
|
||
|
|
- Forked and cloned the repo
|
||
|
|
- Got accustomed to the code
|
||
|
|
- Look up cairo tutorials to understand wtf is going on
|
||
|
|
|
||
|
|
## Week 2
|
||
|
|
- Started coding
|
||
|
|
- `polygons.h` and `polygons.cc`
|
||
|
|
- `polygons_generator.h` and `polygons_generator.cc`
|
||
|
|
- `matrix.h`
|
||
|
|
|
||
|
|
### Polygons properties
|
||
|
|
- points (`std::vector<vec2d>`): the points that form the polygon, **in local
|
||
|
|
coordinates**;
|
||
|
|
- center (`vec2d`): where the origin of the local coordinates lies in global
|
||
|
|
coordinates;
|
||
|
|
- angle (`double`): how the points are rotate around the origin (to keep always
|
||
|
|
the same points but rotating them when making computations are drawing)
|
||
|
|
**interesting question for later: does computing the points rotated at each
|
||
|
|
iteration less computationally efficient than just storing them each time
|
||
|
|
the angle changes?**.
|
||
|
|
|
||
|
|
### Polygon Generator
|
||
|
|
To make life easier for testing different cases, I made a generator of polygons
|
||
|
|
that for now is able to generate any triangle and any rectangle. Simple shapes
|
||
|
|
but that are simple enough to understand what happens when they get hit. We'll
|
||
|
|
then see if the calculation for the forces transpose to any arbitrary polygon.
