#include <SoftBodySharedSettings.h>

Public Member Functions

 DihedralBend ()=default
 Constructor.
 
 DihedralBend (uint32 inVertex1, uint32 inVertex2, uint32 inVertex3, uint32 inVertex4, float inCompliance=0.0f)
 
uint32 GetMinVertexIndex () const
 Return the lowest vertex index of this constraint.
 

Public Attributes

uint32 mVertex [4]
 Indices of the vertices of the 2 triangles that share an edge (the first 2 vertices are the shared edge)
 
float mCompliance = 0.0f
 Inverse of the stiffness of the constraint.
 
float mInitialAngle = 0.0f
 Initial angle between the normals of the triangles (pi - dihedral angle).
 

Detailed Description

A dihedral bend constraint keeps the angle between two triangles constant along their shared edge. 

   x2
  /  \
 / t0 \
x0----x1
 \ t1 /
  \  /
   x3

x0..x3 are the vertices, t0 and t1 are the triangles that share the edge x0..x1
