helper function to create an object to be processed by vcgRaySearch

Description

create a search structure from a matrix of coordinates and one of directional vectors to be processed by vcgRaySearch

Usage

setRays(coords, dirs)

Arguments

coords

k x 3 matrix (or a vector of length 3) containing the starting points of the rays

dirs

k x 3 matrix (or a vector of length 3) containing the directons of the rays. The i-th row of dirs corresponds to the coordinate stored in the i-th row of coords

Value

an object of class "mesh3d" (without faces) and the vertices representing the starting points of the rays and the normals storing the directions.
