◆ Compute_Point_On_Shell()
HC_BOOLEAN Compute_Point_On_Shell | ( | const HC_POINT * | test_point, |
double | tolerance, | ||
int | point_count, | ||
const HC_POINT * | points, | ||
int | face_list_length, | ||
const int * | face_list | ||
) |
Tests whether a given point is on the surface of a shell.
- Parameters
-
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() ).
- Returns
- flag
DETAILS
Compute_Point_On_Shell returns true if test_point is on the surface of the shell, and false otherwise.
NOTES
Models that use non-planar faces may also cause this function to generate incorrect results.
