ClosestLinePoints
From Solid Graphics Wiki
| ||||||||||||
The ClosestLinePoints function calculates positions and coordinates of closest points of two lines.
void ClosestLinePoints
(
const float P0[ 3 ],
const float P1[ 3 ],
const float Q0[ 3 ],
const float Q1[ 3 ],
float *s,
float *t = NULL,
float PC[ 3 ] = NULL,
float QC[ 3 ] = NULL
);
void ClosestLinePoints
(
const double P0[ 3 ],
const double P1[ 3 ],
const double Q0[ 3 ],
const double Q1[ 3 ],
double *s,
double *t = NULL,
double PC[ 3 ] = NULL,
double QC[ 3 ] = NULL
);
Parameters
| P0 | x,y,z coordinates of first point defining the first line |
| P1 | x,y,z coordinates of second point defining the first line |
| Q0 | x,y,z coordinates of first point defining the second line |
| Q1 | x,y,z coordinates of second point defining the second line |
| s | the function will store into variable pointed by s position of closest point lying on the first line. The line position can be then translated to point coordinates using the LinePositionToPoint function. |
| t | if the parameter is not NULL then the function will store into variable pointed by t position of closest point lying on the second line. |
| PC | if the parameter is not NULL then the function will store into variable pointed by PC coordinates of the closest point lying on the first line. |
| QC | if the parameter is not NULL then the function will store into variable pointed by QC coordinates of the closest point lying on the second line. |
