Obb vs aabb collision

  • Sphere vs AABB collision detection test. By Kent, last updated October 15, 2019. As the sphere is being the simplest primitive there is, the test for Sphere and AABB intersection is easy. This solution works also for Sphere Cube intersection tests.

Defines the transition between AABB and OBB in the collision tree. This is the number of the deepest (close to triangles) levels represented by OBB (coarser levels will use AABB). By default if the triangle mesh is deformable, only one level of OBB is used (every other level uses AABB as it is faster to update).

A common approach to collision detection is to simply test for whether two objects are overlapping at the end of each frame. ... Converting an OBB to an AABB merely involves calculating the ...
  • Collision detection (for simulated objects) • Axis-aligned bounding box (AABB) query structure • Constructs a B-tree (or higher branching-order tree, depending on construction) with individual collision primitives at the leaves • Bounding boxes are aggregated, as we go from the leaves to the root of the tree
  • OBBs are constructed for each joint of the character and a point+OBB test was to be done to detect collision. However, I transformed the colliding point into the space of the OBB so that this converts the OBB to an Axis-Aligned Bounding Box (AABB).

Among them, AABB tree tend to have fast overlap test, but require many such tests to perform collision detection. The OBB-Tree is more efficient than other hierarchical trees because of its tightest bounding box but the

    OBB. Oriented Bounding Box stands for a 3D volume relative to a given origin and angle. Difference. In many applications the bounding box is aligned with the axes of the co-ordinate system, and it is then known as an AABB. To distinguish the general case from an AABB, an arbitrary bounding box is sometimes called an OBB.

    AABB vs AABB is a box vs box or bounding box collision detection. It's mainly used in broadphase physics detection. Assume that a center point and halfwidth extents or radius are the basic properties of an AABB (there are several methods to represent AABB structure). This is a C++ code example for AABB structure:
