GEOakimaInterpolation

Calculates a point on the curve between two Splinepunkten.

From before with GEOakimaParameter to two successive Splinepunkten calculated coefficient and the relative distance to the front one of the both a point on the curve is calculated between them. The relative distance is given as a value by 0 to including 1. So. corresponds 0 to the front point, 1 to the rear and 0.5 to a point possibly at the middle of the curve between them.

Parametre

koeff (stands in *) [IN]

The coefficients to two successive Splinepunkten.

see (stands in) [IN]

The relative distance to the front one of both Splinepunkte, the value area is 0 to including 1.

x (stands in *) [OUT]

y (stands in *) [OUT]

The calculated point co-ordinates.

Result

(long int) [OUT]

0 - OK: successful calculation.

1 - Mistake: Calculation not possibly.

Declaration

);

Example

stand in x, y;

status = GEOakimaInterpolation (koeff, 0.1, &x, &y);

The coefficients koeff must be given to two successive bases of the Splines, then the x and Y co-ordinate is determined with zehntel of the curve between them. status must have afterwards the value 0.
