Abstract
A method and apparatus to perform a ray-node intersection test are provided. The method includes receiving an input representing coordinates of a bounding box and an origin coordinate of a ray as fixed-point numbers, obtaining difference values between the input coordinates of the bounding box and the origin coordinate, and obtaining multiplication values between the obtained difference values and a reciprocal number of a direction vector of the ray, where the reciprocal number is a floating-point number.
