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.
