| 22 | class Bisec from Bisector |
| 23 | |
| 24 | --- Purpose : Bisec provides the bisecting line between two elements |
| 25 | -- This line is trimed by a point <P> and it's contained in the domain |
| 26 | -- defined by the two vectors <V1>, <V2> and <Sense>. |
| 27 | -- |
| 28 | -- Definition of the domain: |
| 29 | -- if <Sense> is true the bisecting line is contained in the sector |
| 30 | -- defined by <-V1> and <-V2> in the sense indirect. |
| 31 | -- if <Sense> is false the bisecting line is contained in the sector |
| 32 | -- defined by <-V1> and <-V2> in the sense direct. |
| 33 | -- |
| 34 | -- <Tolerance> is used to define degenerate bisector. |
| 35 | -- if the bisector is an hyperbola and one of this radius is smaller |
| 36 | -- than <Tolerance>, the bisector is replaced by a line or semi_line |
| 37 | -- corresponding to one of hyperbola's axes. |
| 38 | -- if the bisector is a parabola on the focal length is smaller than |
| 39 | -- <Tolerance>, the bisector is replaced by a semi_line corresponding |
| 40 | -- to the axe of symetrie of the parabola. |
| 41 | -- if the bisector is an ellipse and the minor radius is smaller than |
| 42 | -- <Tolerance>, the bisector is replaced by a segment corresponding |
| 43 | -- to the great axe of the ellipse. |
