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();
}
