### Find the Contact Normal of Rectangle Collision

It seems a lot of people have asked similar questions on this site, and every time it seems like a whole bunch of answers that don't work are given. Basically, I have two rectangles (AABBs) that ...

### Calculate an AABB for bone animated model

I have a model that has its initial bounding box calculated by finding the maximum and minimum on the x, y and z axes. Producing a correct result like so: The vertices are then stored in a VBO and ...

### Trouble with AABB collision response and physics

I have been racking my brain trying to figure out a problem I am having with physics and basic AABB collision response. I am fairly close as the physics are mostly right. Gravity feels good and ...

### collision resolve sphere-aabb and aabb-aabb [closed]

I am currently working on a basic physics engine which does not consider rotations. At the moment I work on collision resolving between aabbs and spheres. Unfortunately I have no idea what a collision ...

### How should I do AABB::contains?

Should an AABB "contain" a point when the point is: Exclusive: Only exactly inside the aabb Inclusive: Inside the aabb or exactly on the sides Almost: Inside the aabb or a little bit outside of the ...

### AABB Sweeping, algorithm to solve “stacking box” problem

I'm currently working on a simple AABB collision system and after some fiddling the sweeping of a single box vs. another and the calculation of the response velocity needed to push them apart works ...

### What has the most efficient intersection test against an AABB tree - OBB, Cylinder or Capsule?

I'm currently trying to find collisions in 3D between a tighter volume than an AABB and a tree of AABB volumes. I just need to know whether they are intersecting, no closest distance or collision ...

### How do I avoid 3D AABB collision response getting stuck at block edges?

I want the player to be able to slide along cubes, but without getting caught at the seam between 2 adjacent cubes. I've gotten it so that I can do x collision, with sliding, and y, and z, but I can'...

### How do I make a collision between AABBs slide?

I have a room with objects inside. Each object has it's own AABB. I know how to check for collisions between the objects with an AABB-AABB intersection. How do I calculate an appropriate collision ...

### How do I avoid causing more collisions, when resolving multiple AABB collisions?

I have a lot of AABB bouncing on the screen. Doing collision/response between 2 AABB is fairly easy, but how do you handle this when you can be pulling AABB's apart but making them getting into ...

### Bounding box of a rotated rectangle (2d)

I can see this has been asked before in various ways. I am struggling to work it out though hence asking again. 2d sprite that moves and rotates. I'm looking to contain it in a bounding box as it ...

### Movement and Collision with AABB

I'm having a little difficulty figuring out the following scenarios. In scenario A, the moving entity has fallen to (and slightly into the floor). The current position represents the projected ...

### AABB for a tile based world

I'm on my way with a tiled based game. I have correctly implemented scrolling, position handling etc. I have (before) had a simple collision system that is a really bad one, and now I'm going to ...
