Q3Param2D_RRatio
You can use the Q3Param2D_RRatio function to find a point lying between two given two-dimensional parametric points that is at a desired distance ratio from one of those points.
TQ3Param2D *Q3Param2D_RRatio (
const TQ3Param2D *p1,
const TQ3Param2D *p2,
float r1,
float r2,
TQ3Param2D *result);
p1
- A two-dimensional parametric point.
p2
- A two-dimensional parametric point.
r1
- A floating-point number.
r2
- A floating-point number.
result
- On exit, the two-dimensional parametric point that is at a desired distance ratio from
p1 along the line segment between p1 and p2.
DESCRIPTION
The Q3Param2D_RRatio function returns, as its function result and in the result parameter, the two-dimensional parametric point that lies on the line segment between the points p1 and p2 and that is at a distance from the first parametric point determined by the ratio r1/(r1 + r2).
