Tests whether a given point is on the surface of a shell.
test_point | - point to test. Passed by reference. |
tolerance | - Distance from shell, in object space, inside which a point will be considered to be on the shell. |
point_count | - number of points in the shell that may enclose point |
points | - Vector of x-y-z triplets for the coordinates of the vertices to be used to build the shell. (A simple N x 3 array may also be used). Passed by reference always. |
face_list_length | - size of the array of integers that defines the faces in face_list |
face_list | - Encoded description of how to connect the points to build the faces of the shell (see Insert_Shell() ). |
Compute_Point_On_Shell returns true if test_point is on the surface of the shell, and false otherwise.
Models that use non-planar faces may also cause this function to generate incorrect results.
