An axis-aligned bounding box (AABB) is a box aligned with the axes of a Cartesian co-ordinate frame. AABB's are commonly employed as a cheap way to approximate more complex geometries in a range of applications, including collision detection.

An axis-aligned bounding box (AABB) is a box aligned with the axes of a Cartesian co-ordinate frame. AABB's are commonly employed as a cheap way to approximate more complex geometries in a range of applications, including collision detection.

An AABB can also be referred to as the Axis-aligned minimum bounding box (that is, the smallest box which can encapsulate a geometry)

Ray AABB intersect test fails when AABB is rotated

I am doing Ray intersection test with AABB.It works fine till I start rotating the AABB contained object.My AABBs by default have normalized coordinated ranging from (-1 , 1) ,so in order to get them into Object's world dimensions I update AABB…

Box2D: Getting Child Index through Report Fixture

Using Box2D 2.2.0, I'm working on a game using Box2D. The player shoots AABBs. In each step() I move the AABB and handle collisions by going through b2World->QueryAABB( &queryCallback, aabb ). However, my game world is made up of chain shapes. So…

passing AABB tree: serialization of AABB tree?

I'm trying to parallelize my code, and I'm using a CGAL's AABB tree for interference detection (pretty neat efficiency btw :) ). No problem on a single machine (I'm not saying it's multi-threaded, but that's another story), but I now want to do…

Creating and using AABB for collision detection 3d (OpenGL)

Suppose I have a square that I have created in the following way: glBegin(GL_QUADS); glColor3f(0.0f,1.0f,0.0f); glVertex3f( 1.0f, 1.0f,-1.0f); glVertex3f(-1.0f, 1.0f,-1.0f); glVertex3f(-1.0f, 1.0f, 1.0f); glVertex3f( 1.0f, 1.0f, 1.0f); …

Finding original width and height of AABB

I have a rotated rectangle that I don't know the original width and height of. As the current width and height is just the bounding box encapsulating the rectangle, how would I find the actual width and height? thanks.

3d aabb as key in map

I need 3D AABB(axis aligned bounding box) as key in map. The main concern is, there must not be pair of AABB keys in map which somehow intersect each other. I don't know which structure/container should i use. Any suggestions?

Check collision between two bounding boxes in Away3D?

I need to do some simple collision detection in Away3D. I found the away3d.bounds.AxisAlignedBoundingBox class, but it seems I can only check collisions between the bounding box and a Vector. Is there any way to check the collision between two…
