17 | class RstRstLineBuilder from BRepBlend |
18 | |
19 | ---Purpose: This class processes the data resulting from |
20 | -- Blend_CSWalking but it takes in consideration the Surface |
21 | -- supporting the curve to detect the breakpoint. |
22 | -- |
23 | -- As a result, the criteria of distribution of |
24 | -- points on the line become more flexible because it |
25 | -- should calculate values approached |
26 | -- by an approximation of continued functions based on the |
27 | -- Blend_RstRstFunction. |
28 | -- |
29 | -- Thus this pseudo path necessitates 3 criteria of |
30 | -- regrouping : |
31 | -- |
32 | -- 1) exit of the domain of the curve |
33 | -- |
34 | -- 2) exit of the domain of the surface |
35 | -- |
36 | -- 3) stall as there is a solution of problem |
37 | -- surf/surf within the domain of the surface |
38 | -- of support of the restriction. |
