Ray obb intersection
WebComputing the intersection of a ray with an AABB is quite simple. All we need is to remember that a straight line can be defined as: y = m x + b. In mathematics, the m term is called the slope (or gradient) and is … WebWith AABB out of the way, now it's time to learn about OBB, known as Oriented Bounding Boxes. The idea is the same as AABB, where you test each axis as a sin...

Web1) All points are in front of the plane, no collision 2) All points are behind the plane, no collision 3) Some points are in front of the plane, some are behind. COLLISION. That is to say, if you encounter any points that are not on the same side of the plane, a collision has occured. The hardest thing about the brute force approach is figuring ... WebI've implemented an algorithm that tests for a Ray vs AABB intersection functioning fine. I have also implemented detection of a Ray Vs OBB. When using the normal of the intersection to counter the object's velocity, I am needing to add an offset to the normal to make the resolution properly work.
