db_count_curves_for_point | ( id, count ) |
Description: | ||
Counts all curves associated with a specified point in the database. | ||
Input: | ||
INTEGER | id | The id of the point to which the curves are associated. |
Output: | ||
INTEGER | count | The integer number of curves associated to the point in the database. |
INTEGER | <Return Value> | Integer indicating success or failure of the routine. If the routine failed, this value contains an indication of the reason. |
Error Conditions: | ||
13000097 | Curve input was not found. | |
db_get_curves_for_point | ( ptid,count,crvid) |
Description: | ||
Finds the ids of all curves associated with a specified point in the database. | ||
Input: | ||
INTEGER | ptid | Id of the point to which the curves are associated. |
INTEGER | count | The number of curves that the calling routine expects to receive from the database. This count should be the same as the number of curves to which the point is associated as it should have been fetched from the database prior to making this call. |
Output: | ||
INTEGER | crvid() | Ids of the various curves associated with the specified point. |
sgm_db_get_edge_vertex_ids | ( edgeid, vertexids ) |
Description: | ||
This function returns the vertex id values foran edge. | ||
Input: | ||
INTEGER | edgeid | This value specifies the id of an edge. |
Output: | ||
INTEGER | vertexids ( ) | This value returns the id values of the vertices of an edge. |
INTEGER | <Return Value> | 0 if the function was successful. |
sgm_nearest_point_on_curve | (location, curve_data, parameter, point_location) |
Description: | ||
This function gets the nearest point at a specific parametric location on a curve. | ||
Input: | ||
REAL ARRAY | location(3) | The xyz location of the point in space. |
REAL ARRAY | curve_data() | The blob of the curve. The functions to be used for getting the blob are sgm_db_get_blob_size() followed by sgm_db_get_curve(). |
REAL | parameter | The parameter value along the curve where to look for the nearest point. |
Output: | ||
REAL ARRAY | point_location(3) | The xyz location of the nearest point in space. |
INTEGER | <Return_value> | This function returns a value of 0 when executed successfully and a non zero value to indicate a change in status or an error. |
Error Conditions: | ||
See the Status Messages (Ch. 11) for information on any error values returned by this function. | ||

Description: | ||
This function gets the nearest point at a specific parametric location on a curve. | ||
Input: | ||
REAL ARRAY | location(3) | The xyz location of the point in space. |
REAL ARRAY | curve_data() | The blob of the curve. The functions to be used for getting the blob are sgm_db_get_blob_size() followed by sgm_db_get_curve(). |
REAL | parameter | The parameter value where to look for the nearest point. |
Output: | ||
REAL ARRAY | point_location(3) | The xyz location of the nearest point in space. |
INTEGER | <Return_value> | This function returns a value of 0 when executed successfully and a non zero value to indicate a change in status or an error. |
Error Conditions: | ||
See the Status Messages (Ch. 11) for information on any error values returned by this function. | ||
xy_curve_num_points_get | (<curve_name>,<yonly>,<npoints>) |
Description: | ||
This function will get the number of points on the curve. | ||
Input: | ||
STRING | curve_name | Name of the curve. |
Output: | ||
LOGICAL | yonly | Flag which is TRUE if curve uses only y values and FALSE if curve uses both xy values. |
INTEGER | npoints | Number of points on the curve. |
INTEGER | <Return Value> | Returns 0 for success, otherwise returns the error code. |
Error Conditions: | ||
