23 | class BSplineSurface from DrawTrSurf |
24 | |
25 | inherits Surface from DrawTrSurf |
26 | |
27 | --- Purpose : |
28 | -- This class defines a drawable BSplineSurface. |
29 | -- With this class you can draw the control points and the knots |
30 | -- of the surface. |
31 | -- You can use the general class Surface from DrawTrSurf too, |
32 | -- if you just want to sea boundaries and isoparametric curves. |
33 | |

47 | -- The isoparametric curves corresponding to the knots values are |
48 | -- drawn. |
49 | -- The control points and the knots points are drawn. |
50 | -- The boundaries are yellow, the isoparametric curves are blues. |
51 | -- For the discretisation 50 points are computed in each parametric |
52 | -- direction. |
