setRays: 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)

Value

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

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
