Returning points from an interpolated BSpline

Posted by O.Famous O. at February 06. 2013

Hello Everyone,

I am trying to create a 3D BSpline by interpolating through 6 control points. I can see this is possible in Salome. I also want to get other points along the BSpline. How is this possible? Let's say Salome creates the BSpline using 40 positions between the first and last control points, can I get the X,Y,Z coordinates of these 40 positions from Salome (e.g. as a pointer to array of 3D points)? I will appreciate any suggestions.

Regards

Famous.

Hi Famous

What one can get is a point at a certain position along the curve (edge).
In TUI mode this feature is accessible by calling geompy.MakeVertexOnCurve( theCurve, theParameter ).
In GUI, you can get coordinates of a point on curve via "Create a point" command, 3d button (variant of construction).
