Remarks

This interface is implemented by all ten TIN renderers at ArcGIS 9.0.  It provides the basic info for a specific TIN renderer.  The following sample VBA code shows a way to query a TIN renderer's name and visibility properties in ArcMap:

Sub ShowTinRenderer()
  Dim pDoc As IMxDocument: Set pDoc=ThisDocument
  Dim pMap As IMap: Set pMap=pDoc.Maps.Item(0)     'assuming we're working on the first map
  Dim pTinLyr As ITinLayer: Set pTinLyr=pMap.Layer(0)    'assuming the first layer is a TIN layer
 
  Dim i As Integer
  For i=0 To pTinLyr.RendererCount - 1
    Dim pTinRenderer As ITinRenderer
    Set pTinRenderer=pTinLyr.GetRenderer(i)
    Debug.Print pTinRenderer.Name, pTinRenderer.Visible
  Next i
End Sub

A TIN layer can have one of more TIN renderers.  When you load a TIN dataset into an application, two default TIN renderers are added.  Depending on applications, the two default TIN renderers vary.  In ArcMap, the two default TIN renderers are Edge Type and Elevation renderers.  In ArcScene, they're Edge Type and Faces.

The order of TIN renderers in the application has an effect on how the TIN is drawn.  In ArcMap, the effect is the same as that in the the TOC in general; higher ones get drawn on top of the lower ones.  In ArcScene, rendering conflict may arise if multiple renderers are drawn simultaneously (especially with face renderers) and that should be avoided.
