WebOct 21, 2024 · A ray is a path extending infinitely in a given direction from an origin point. We typically use a parametric definition of a ray: r → ( t) = p + d → t. The ray r → ( t) above starts at point p and travels in the direction d →. We can define points along the ray with the parameter t. At t = 0, we are at the point p.
