tessellate1()

subroutine, public tessellate1	(	class(oft_bmesh), intent(in)	self,
		real(r8), dimension(:,:), intent(out), pointer	rtmp,
		integer(i4), dimension(:,:), intent(out), pointer	lctmp
	)

Construct point and face lists for a single tessellation.

This corresponds to the input triangulation with no refinement

• np_tess = np
• nc_tess = nc

  Parameters

  [in]	self	Mesh object
  [out]	rtmp	Tessellated point list [3,np_tess]
  [out]	lctmp	Tessellated cell list [4,nc_tess]

tessellate2()

subroutine, public tessellate2	(	class(oft_bmesh), intent(in)	self,
		real(r8), dimension(:,:), intent(out), pointer	rtmp,
		integer(i4), dimension(:,:), intent(out), pointer	lctmp
	)

Construct point and face lists for a 2 level tessellation.

This corresponds to the input triangulation with no refinement

• np_tess = np + ne
• nc_tess = 4*nc

  Parameters

  [in]	self	Mesh object
  [out]	rtmp	Tessellated point list [3,np_tess]
  [out]	lctmp	Tessellated cell list [4,nc_tess]

tessellate3()

subroutine, public tessellate3	(	class(oft_bmesh), intent(in)	self,
		real(r8), dimension(:,:), intent(out), pointer	rtmp,
		integer(i4), dimension(:,:), intent(out), pointer	lctmp
	)

Construct point and face lists for a 3 level tessellation.

This corresponds to the input triangulation with no refinement

• np_tess = np + 2*ne + nc
• nc_tess = 9*nc

  Parameters

  [in]	self	Mesh object
  [out]	rtmp	Tessellated point list [3,np_tess]
  [out]	lctmp	Tessellated cell list [4,nc_tess]

tessellate4()

subroutine, public tessellate4	(	class(oft_bmesh), intent(in)	self,
		real(r8), dimension(:,:), intent(out), pointer	rtmp,
		integer(i4), dimension(:,:), intent(out), pointer	lctmp
	)

Construct point and face lists for a 4 level tessellation.

This corresponds to the input triangulation with no refinement

• np_tess = np + 3*ne + 3*nc
• nc_tess = 16*nc

  Parameters

  [in]	self	Mesh object
  [out]	rtmp	Tessellated point list [3,np_tess]
  [out]	lctmp	Tessellated cell list [4,nc_tess]
