                     Vector2f pkUVMax)

  Construction and destruction. If rkUpVector is not the zero vector, it will be used as 'up' in the frame calculations. If it is the zero vector, the Frenet frame will be used. If bWantColors is 'true', the vertex colors are allocated and set to black. The application needs to assign colors as needed. If either of pkUVMin or pkUVMax is not null, both must be not null. In this case, texture coordinates are generated for the surface.

  Parameters:

  pkMedial -

  oRadial -

  bClosed -

  rkUpVector - If rkUpVector is not the zero vector, it will be used as 'up' in the frame calculations. If it is the zero vector, the Frenet frame will be used.

  iMedialSamples - control tessellation

  iSliceSamples - control tessellation

  rkAttr -

  bSampleByArcLength -

  bInsideView -

  pkUVMin - if not null, generate texture coordinates

  pkUVMax - if not null, generate texture coordinates

• GetTMaxSlice

  public void GetTMaxSlice​(Vector3f[] akSlice)

  Generate vertices for the end slices. @see GetTMinSlice()

  Parameters:

  akSlice - slice list

• GetTMinSlice

  public void GetTMinSlice​(Vector3f[] akSlice)

  Generate vertices for the end slices. These are useful when you build an open tube and want to attach meshes at the ends to close the tube. The input array must have size (at least) S+1 where S is the number returned by GetSliceSamples. Function GetTMinSlice is used to access the slice corresponding to the medial curve evaluated at its domain minimum, tmin. Function GetTMaxSlice accesses the slice for the domain maximum, tmax. If the curve is closed, the slices are the same.

  Parameters:

  akSlice - slice list

• UpdateSurface

  public void UpdateSurface()

  If the medial curve is modified, for example if it is control point based and the control points are modified, then you should call this update function to recompute the tube surface geometry.
