Ray-Box Intersection Figure 1: equation of a line. The equation of a line can be written as y=mx+b. For the oblique line which equation is y=x-1 we have m=1 and b=-1. In the following example, we will assume that the box is aligned with the …

Ray tracing box intersection (c++) Ask Question Asked 7 years, 5 months ago. Modified 7 years, 4 months ago. Viewed 1k times -1 I have 2 entities and a wall between them, i'm trying to detect the collision using ray tracing intersection but for some reason it's not detecting the bounding box. I'm using an existing ray, vector3 & box classes.
A Ray-Box Intersection Algorithm
https://www.jcgt.org/published/0007/03/04/paper-lowres.pdf
The core of this method is a new algorithm for computing the intersection point and normal of a 3D ray with an arbitrarily-oriented 3D box, which also has non-rendering applications in GPU physics, such as ray casting and particle collision de- tection.

For example if your box intersection is not working, test situations were you know what the correct answer will be. i.e. box with corner at (0,0,0) of size (1,1,1) intersecting with a ray at (-1,0.5,0.5) moving along (1,0,0) will hit at (0,0.5,0.5), this sort of thing.

•Typically weoffset the ray by half of the pixel width and height, i.e, cast the ray from the pixel center e s s-e incrementing (i,j) (0,0) Put it all together •We can represent the ray as a 3D parametric line p(t) = e+ t (s-e) (now you know how to get s and e)
Fast, Branchless Ray/Bounding Box Intersections
https://tavianator.com/2011/ray_box.html
Axis-aligned bounding boxes (AABBs) are universally used to bound finite objects in ray-tracing. Ray/AABB intersections are usually faster to calculate than exact ray/object intersections, and allow the construction of bounding volume hierarchies (BVHs) which reduce the number of objects that need to be considered for each ray.
Ray Tracing: Rendering a Triangle (Ray-Triangle …
https://www.scratchapixel.com/lessons/3d-basic-rendering/ray-tracing-rendering-a-triangle/ray-triangle-intersection-geometric-solution
The ray can intersect the triangle or miss it. If the ray is parallel to the triangle there is not possible intersection. This situation occurs when the normal of the triangle and the ray direction are perpendicular (and the dot product of these two vectors is 0). We have learned that the dot product of two perpendicular vectors is 0.
