std::vector faster than std::unordered_set? @stardust_ I understand. Do you think there is any way to speed up this method? Maybe using a custom stack allocator could improve the performance? |

std::vector faster than std::unordered_set? I tried it, but the performance is slower than what I currently have. |

std::vector faster than std::unordered_set? As I only care about returning a collection of unique Body*, I didn't use "contains" or "find" on unordered_set. I just used insert expecting it to only be filled with unique elements. |

std::vector faster than std::unordered_set? @stardust_ Profiler shows "getBodiesToCheck()" method as the bottleneck. If I use the std::vector version, the bottleneck inside getBodiesToCheck() (bottleneck of the bottleneck :P) is the call to "contains" |

Getting cells in a 2D grid between two angles Good idea. I understand how to do it for one quadrant, but I'm confused on how I should handle different quadrants, or a situation where a ray is in a quadrant and the other ray is in another quadrant. What if the rays make a 180° angle? How can I "walk" the inner cells for the quadrants in the middle? |
