So, for example, if you are intersecting the plane at xx0, and your ray is going in direction (rx,ry,rz) from (0,0,0), then the time of intersection is t x0/rx. #Ray box intersection fullCompute intersection between 3D triangles use Test () for fast boolean query, does not compute intersection info use Find () to compute full information By default fully-contained co-planar triangles are not reported as intersecting. raysect.primitive import Box, Subtract from import. We will then successively compute the two parametric positions where the ray intersects each axis-aligned slab. TIntersector1 computes the intersection of one-dimensional intervals u0,u1 and v0,v1. In Figure 1 the 3D hit point for each ray in the camera is plotted in 3D space.

The basic ray-bounding box intersection algorithm works as follows: we start with a parametric interval that covers that range of positions along the ray where we’re interested in finding intersections typically, this is.
