ArcGIS Engine中如何设置内存缓存的大小

ArcGIS 10中的三维效率不错，运行很快是需要做优化的，其中非常重要的一点就是内存缓存的设置。在ArcGLobe中通过GlobeOption我就可以弹出选项卡，通过页面来设置各个需要内存的分配比例。那么ArcGIS Engine自己写的程序又是如何进行内存分配呢？下面分享ArcGIS Engine设置Memory Cache的方法。

Sub MemoryLimits()
  Dim pDoc As IGMxDocument: Set pDoc = ThisDocument
  Dim pScene As IScene: Set pScene = pDoc.Scene
  Dim pGlobe As IGlobe: Set pGlobe = pScene
  Dim pGP As IGlobeDisplay: Set pGP = pGlobe.GlobeDisplay
 
  Dim pOptions2 As IGlobeAdvancedOptions2: Set pOptions2 = pGP.AdvancedOptions
  Debug.Print "esriGlobeTileMemory:"
  Dim iLimit As Long, sglCurrent As Single
  Dim i As Integer, iTotal As Integer
  For i = 0 To 6
    pOptions2.GetTileMemory i, iLimit, sglCurrent
    Debug.Print ConvertI(i), iLimit, sglCurrent
'    pOptions2.SetTileMemory i, iLimit + 10
'    Debug.Print i, iLimit, sglCurrent
    iTotal = iTotal + iLimit
  Next i
  Debug.Print "Total Size of Memory Cache: ", iTotal
End Sub

 

Function ConvertI(i As Integer) As String
 
  Select Case i
    Case 0
      ConvertI = "Image"
    Case 1
      ConvertI = "Elevation"
    Case 2
      ConvertI = "Point"
    Case 3
      ConvertI = "Line"
    Case 4
      ConvertI = "3DGeom"
    Case 5
      ConvertI = "3DTexture"
    Case 6
      ConvertI = "Text"
  End Select

 

End Function
