GetTessellationQuality Method (IModelDoc2)

Gets the tessellation quality index for the application.

.NET Syntax

Visual Basic (Declaration) 
Function GetTessellationQuality() As System.Integer
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim value As System.Integer
value = instance.GetTessellationQuality()
System.int GetTessellationQuality()
System.int GetTessellationQuality(); 

Return Value

Number between 0 and 106 that indicates the quality of tessellation to use for this part (see Remarks)


This method returns the Shaded Display Quality setting that you find on the Tools,  Options, Performance menu. The numeric deviation value changes based on the current part. This deviation is calculated as follows:

Deviation = 0.025 * (BodyDiameter) / qualityIndex;


BodyDiameter is the diagonal distance across the bounds of the part box. See IPartDoc::GetPartBox or IPartDoc::IGetPartBox for more information.

The resulting deviation value is in meters.

NOTE: Setting the index of the tessellation to a higher value results in:

  • finer tessellation,
  • increased file size,
  • slower graphics performance, and
  • increased memory usage.
