c++ - Ray tracing box intersections - Stack Overflow
https://stackoverflow.com/questions/8903356/ray-tracing-box-intersections
So I'm back with another ray tracing question. My code renders spheres all fine and dandy, but cubes aren't really working. ... The bounding box is defined as: Cube* c1 = new Cube; c1->Corner1 = Vec3(100, 100, 100); c1->Corner2 = Vec3(200, 200, 200); I've confirmed that the camera is not inside the cube. Now, the only problem is that the entire ...

Because we have a root of multiplicity 2, ray intersects circle at one point (i.e., it’s tangent to the circle) We can use discriminant D = b2 - 4ac to quickly determine if a ray intersects a curve or not - if D < 0, imaginary roots; no intersection - if D = 0, double root; ray is tangent - if D > 0, two real roots; ray intersects circle at ...

A: Project r onto cube face. ( rx, ry, rz) = ( rx, ry, rz) / max { | rx | , | ry | , | rz | }. One of the components will have value +- 1, and this tells us which face of the cube to use. The other two components are used for indexing into that face. Need to remap the indices from [-1, 1] to [0, N) where each face of the cube map has NxN pixels.

c,y. c,z. c) and radius R can be represented as: (x-x. c) + (y-y. c) + (z-z. c) - R = 0 For a point pon the sphere, we can write the above in vector form: (p-c). (p-c) - R = 0 (note ‘.’ is a dot product) We can plug the point on the ray p(t) = e+ t d. (e+td-c). (e+td-c) - R = 0 and yield (d.d) t + 2d.
