GetTessTriStrips Method (IPartDoc)

Gets the vertices that make up the shaded picture tessellation for this part.

.NET Syntax

Visual Basic (Declaration) 
Function GetTessTriStrips( _
   ByVal NoConversion As Boolean _
) As Object
Visual Basic (Usage) 
Dim instance As IPartDoc
Dim NoConversion As Boolean
Dim value As Object
 
value = instance.GetTessTriStrips(NoConversion)
C# 
object GetTessTriStrips( 
   bool NoConversion
)
C++/CLI 
Object^ GetTessTriStrips( 
&   bool NoConversion
) 

Parameters

NoConversion

True prohibits converting to user units from system units, false does not

Return Value

Array of floats (see Remarks)

Remarks

The vertices are all unique for that strip. In other words, a vertex that is shared by two tessellation triangles will only appear once in the return value.

These triangles are intended for graphics display purposes and do not represent a tessellation that could be used, for example, by a machining application. If you need the type of accuracy associated with a machining product, it is recommended that you traverse the body faces and extract the topology and geometry data to create your own faceting.

These triangles are intended for graphics display purposes and do not represent a tessellation that can be used, for example, by a machining application. If you need the level of accuracy associated with a machining product, traverse the body faces and extract the topology and geometry data to create your own faceting.

This method returns an array of float values in the form of:

[NumStrips,

 VertexPerStrip1, VertexPerStrip2,..., VertexPerStripN,

 VertexPoints1[VertexPerStrip1 elements]*3,

 VertexPoints2[VertexPerStrip2 elements]*3,...,

 VertexPointsN[VertexPerStripN elements]*3]

where:

NumStrips = number of triangle strips on a particular face.

VertexPerStripN = number of vertex points for the Nth triangle strip.

VertexPointsN = a sub-array of vertices consisting of three float values representing the x,y,z coordinate of the vertex; the sub-array's length is defined by the VertexPerStripN element in the array.

Because the values NumStrips and the elements of VertexPerStrip are long values  packed into single values,  you must unpack them before they can be used.
