Examples

The following example shows how to use the Unlock method.

' Create several meshes and associated data.
Dim i As Integer
For i = 0 To numberOfMeshes
    Dim vertexData As GraphicsStream

    meshes(i) = Mesh.Box(device, 1F, 1F, 1F)

    ' Arrange the boxes in a grid, with each
    ' successive box farther in the distance.
    meshLocations(i) = New Vector3((i Mod 3) * 2 - 2, i / 3 * 2 - 2, i)

    ' Compute the bounding box for a mesh.
    Dim description As VertexBufferDescription = meshes(i).VertexBuffer.Description
    vertexData = meshes(i).VertexBuffer.Lock(0, 0, LockFlags.ReadOnly)
    Geometry.ComputeBoundingBox(vertexData, meshes(i).NumberVertices, description.VertexFormat, meshBoundingBoxMinValues(i), meshBoundingBoxMaxValues(i))
    meshes(i).VertexBuffer.Unlock()
Next i

// Create several meshes and associated data.
for (int i = 0; i < numberOfMeshes; i++)
{
    GraphicsStream vertexData;

    meshes[i] = Mesh.Box(device, 1.0f, 1.0f, 1.0f);

    // Arrange the boxes in a grid, with each
    // successive box farther in the distance.
    meshLocations[i] = new Vector3(((i % 3) * 2) - 2,
                                ((i / 3) * 2) - 2, i);

    // Compute the bounding box for a mesh.
    VertexBufferDescription description =
        meshes[i].VertexBuffer.Description;
    vertexData = meshes[i].VertexBuffer.Lock
                             (0, 0, LockFlags.ReadOnly);
    Geometry.ComputeBoundingBox(vertexData,
        meshes[i].NumberVertices,description.VertexFormat,
        out meshBoundingBoxMinValues[i],
        out meshBoundingBoxMaxValues[i]);
    meshes[i].VertexBuffer.Unlock();
}
