17 | class BSplineSurface from DrawTrSurf |
18 | |
19 | inherits Surface from DrawTrSurf |
20 | |
21 | --- Purpose : |
22 | -- This class defines a drawable BSplineSurface. |
23 | -- With this class you can draw the control points and the knots |
24 | -- of the surface. |
25 | -- You can use the general class Surface from DrawTrSurf too, |
26 | -- if you just want to sea boundaries and isoparametric curves. |

43 | -- The control points and the knots points are drawn. |
44 | -- The boundaries are yellow, the isoparametric curves are blues. |
45 | -- For the discretisation 50 points are computed in each parametric |
46 | -- direction. |
