Set Method (IAgStkGraphicsTriangleMeshPrimitive)
See Also  Example
Positions
An array containing positions (in the order x, y, z) for the triangle mesh.
Normals
An array containing the normals (in the order x, y, z) used for lighting the triangle mesh. There must be one normal for each position in positions.
Indices
An array of integers containing the indices into positions and normals. A set of x, y, and z elements is considered a single index. Every 3 indices represent 1 triangle.





Description

Defines the triangle mesh using an indexed triangle list specified by positions, normals, and indices. The mesh is rendered in the primitive's Reference Frame.

Syntax

[Visual Basic .NET] 
Public Sub Set( _
   ByRef Positions As System.Array, _
   ByRef Normals As System.Array, _
   ByRef Indices As System.Array _
)
[C#] 
public void Set(

   ref System.Array Positions, 

   ref System.Array Normals, 

   ref System.Array Indices

);
[Managed C++] 
public: void Set(

   System::Array ^^ Positions, 

   System::Array ^^ Normals, 

   System::Array ^^ Indices

);
[Java] 
public  set(

   Object[] Positions, 

   Object[] Normals, 

   Object[] Indices

);
[Unmanaged C++] 
public: HRESULT Set(

   SAFEARRAY ** Positions, 

   SAFEARRAY ** Normals, 

   SAFEARRAY ** Indices

);

Parameters

Positions
An array containing positions (in the order x, y, z) for the triangle mesh.
Normals
An array containing the normals (in the order x, y, z) used for lighting the triangle mesh. There must be one normal for each position in positions.
Indices
An array of integers containing the indices into positions and normals. A set of x, y, and z elements is considered a single index. Every 3 indices represent 1 triangle.

Remarks

Example

Shows the format of the Positions, Normals and Indices parameters when updating a triangle mesh primitive.
