Description
A class for drawing properties of beams whose section is a set of M polylines, each with N points.
The shading will show the longitudinal edges extruded at each Nth point as a smooth edge, so if you need sharp edges, just create multiple polylines (ex a quadrialteral=4 polylines). Used as a component of ChBeamSection.

Member Function Documentation
◆ GetNofLines()
|
inlineoverridevirtual |
Get the n.
of lines making the profile of the section, for meshing purposes. C0 continuity is required between lines, C1 also required within each line. Ex. a circle has 1 line, a cube 4 lines, etc. Sharp corners can be done mith multiple lines.
Implements chrono::fea::ChBeamSectionShape.
◆ GetNofPoints()
|
inlineoverridevirtual |
Get the n.
of points to be allocated per each section, for the i-th line in the section. We assume one also allocates a n. of 3d normals equal to n of points.
Implements chrono::fea::ChBeamSectionShape.
◆ GetNormals()
|
inlineoverridevirtual |
Compute the normals (in the reference of the section) at each point.
Note: mnormals must already have the proper size.
Implements chrono::fea::ChBeamSectionShape.
◆ GetPoints()
|
inlineoverridevirtual |
Compute the points (in the reference of the section).
Note: mpoints must already have the proper size.
Implements chrono::fea::ChBeamSectionShape.
