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 Int32Leave Site 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

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




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

OutOfMemoryExceptionLeave Site

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.


SimplificationMesh simplifiedMesh = new SimplificationMesh(mesh, adjacency);

simplifiedMesh.ReduceVertices(mesh.NumberVertices - 25);

mesh = simplifiedMesh.Clone(simplifiedMesh.Options.Value, 
                            simplifiedMesh.VertexFormat, device);
