Description:
|
Creates a two-dimensional radial pattern defined by a root position
center (which may or may not lie upon the seed entity) and the vector
normal, which sets the orientation of the pattern. The number of elements in the radial and angular directions are specified by
num_radial and
num_angular, respectively, and the distance between successive rings of the pattern by the
spacing argument. The optional
start argument specifies the direction of the first spoke of the pattern. The elements of the pattern are kept in a fixed relative orientation if
not_rotate is
TRUE. The
start_angle and
end_angle arguments fix the angular extent of the pattern, while the
ratio argument sets the ratio of minor/major radii of the pattern perimeter. The pattern coordinates are specified in the order (radial, angular).

The following code snippet shows an example of how this API can be used.
|
|
|
// Create a pattern
|
|
pattern* pat = NULL;
|
|
SPAposition center(0, 0, 0);
|
|
SPAvector normal(0, 0, 1);
|
|
int num_radial = 4;
|
|
int num_angular = 5;
|
|
double spacing = 3.0;
|
|
check_outcome(result = api_radial_pattern(pat, center, normal, num_radial, num_angular, spacing));
|
|
|
// Create a prism
|
|
BODY* prism = NULL;
|
|
double height = 1.0;
|
|
double maj_rad = 1.0;
|
|
double min_rad = 0.5;
|
|
int num_sides = 3;
|
|
check_outcome(result = api_make_prism(height, maj_rad, min_rad, num_sides, prism));
|
|
|
// Apply the pattern to the prism
|
|
check_outcome(result = api_set_entity_pattern(prism, pat));
|
|
|
// Clean up
|
|
pat->remove();
