+ * @sa RodMeshSection to define a rod using a mesh file, @sa RodSpireSection or @sa RodStraightSection to define procedural shapes.
+ * Method @sa initSection and @sa getRestTransformOnX should be overriden to provide the correct creation and interpolation.
+ * 
+ * The rod section is described by:
+ * - Topology parameters: vertices and edges @sa d_nbEdgesVisu and @sa d_nbEdgesCollis
+ * - Geometry parameters: radius @sa d_radius, @sa d_innerRadius and length @sa d_length
+ * - Mechanical parameters: @sa d_poissonRatio and @sa d_youngModulus
