SetTessellationQuality Method (IModelDoc2)

Sets the shaded-display image quality number for the current document.

.NET Syntax

Visual Basic (Declaration) 
Sub SetTessellationQuality( _
   ByVal QualityNum As System.Integer _
) 
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim QualityNum As System.Integer
 
instance.SetTessellationQuality(QualityNum)
C# 
void SetTessellationQuality( 
   System.int QualityNum
)
C++/CLI 
void SetTessellationQuality( 
&   System.int QualityNum
) 

Parameters

QualityNum
0 < Shaded-display image quality number < 106 (see Remarks)

Remarks

QualityNum is the degree of tessellation of curved surfaces for shaded rendering output. Tools > Options > Document Properties > Image Quality includes a field that sets the maximum chordal deviation. QualityNum and the maximum chordal deviation (in meters) are coupled and inversely proportional as follows:

var = TessMin + QualityNum*((TessMax-TessMin)/100)

Deviation = 0.025 * (BodyDiameter * 2) / var

where:

There are two ways to set the image quality for assemblies using the API. You can either:

  • Call this method

    - or -

Before doing either, you must set swUserPreferenceToggle_e.swImageQualityApplyToAllReferencedPartDoc to true in order to affect the image quality of the assembly.

Call IModelDoc2::GraphicsRedraw2 after calling this method to update the model.

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

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