Simplify a Mesh

Clones, or copies, a SimplificationMesh object.

Definition

Visual Basic Public Function Clone( _
    ByVal options As MeshFlags, _
    ByVal declaration() As VertexElement, _
    ByVal device As Device, _
    ByRef adjacencyOut As Integer, _

JScript	public function Clone( options : MeshFlags, declaration : VertexElement[], device : Device, adjacencyOut : int, vertexRemap : int ) : Mesh;

Parameters

options Microsoft.DirectX.Direct3D.MeshFlags
Mesh creation options, indicated through one or more MeshFlags flags (excepting the Simplify* and Optimize* flags).

declaration Microsoft.DirectX.Direct3D.VertexElement[]
Vertex data, defined with an array of VertexElement structures.

device Microsoft.DirectX.Direct3D.Device
The Device object associated with the mesh.

adjacencyOut System.Int32[]
Array of three Int32 values per face that specifies the three neighbors for each face in the source mesh.

vertexRemap System.Int32[]
Array that contains the index for each vertex.

Return Value

Microsoft.DirectX.Direct3D.Mesh
Address of a pointer to a Mesh object that represents the cloned mesh.

Remarks

Exceptions

InvalidCallException The method call is invalid. For example, a method's parameter might contain an invalid value.

OutOfMemoryException Microsoft Direct3D could not allocate sufficient memory to complete the call.

Simplify a Mesh

This example demonstrates how to simplify a mesh.

The mesh is simplified by 25 vertices.

In the following C# code example, mesh is assumed to be a Mesh instance that has been properly loaded and cleaned, adjacency is a GraphicsStream instance that contains the mesh adjacency data, and device is the rendering Device.

[C#]
SimplificationMesh simplifiedMesh = new SimplificationMesh(mesh, adjacency); simplifiedMesh.ReduceVertices(mesh.NumberVertices - 25); mesh.Dispose(); mesh = simplifiedMesh.Clone(simplifiedMesh.Options.Value, simplifiedMesh.VertexFormat, device); simplifiedMesh.Dispose();

options	Microsoft.DirectX.Direct3D.MeshFlags Mesh creation options, indicated through one or more MeshFlags flags (excepting the Simplify* and Optimize* flags).
declaration	Microsoft.DirectX.Direct3D.VertexElement[] Vertex data, defined with an array of VertexElement structures.
device	Microsoft.DirectX.Direct3D.Device The Device object associated with the mesh.
adjacencyOut	System.Int32[] Array of three Int32 values per face that specifies the three neighbors for each face in the source mesh.
vertexRemap	System.Int32[] Array that contains the index for each vertex.

InvalidCallException	The method call is invalid. For example, a method's parameter might contain an invalid value.
OutOfMemoryException	Microsoft Direct3D could not allocate sufficient memory to complete the call.
