SetWithOptionalParameters 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.

OptionalParameters: Optional parameters corresponding to positions.

Description

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

Syntax

[Visual Basic .NET]
Public Sub SetWithOptionalParameters( _ ByRef Positions() As Variant, _ ByRef Normals() As Variant, _ ByRef Indices() As Variant, _ ByVal OptionalParameters As IAgStkGraphicsTriangleMeshPrimitiveOptionalParameters _ )

[Visual Basic .NET]

Public Sub SetWithOptionalParameters( _
   ByRef Positions() As Variant, _
   ByRef Normals() As Variant, _
   ByRef Indices() As Variant, _
   ByVal OptionalParameters As IAgStkGraphicsTriangleMeshPrimitiveOptionalParameters _
)

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.
OptionalParameters: Optional parameters corresponding to positions.

Remarks

See Triangle Mesh Primitive Optional Parameters for details on how to define parameters.

Example

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