MeshGeometry3D Class

Triangle primitive for building a 3-D shape.

Namespace: System.Windows.Media.Media3D
Assembly: PresentationCore (in PresentationCore.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/xaml/presentation

Syntax

Visual Basic (Declaration)

Public NotInheritable Class MeshGeometry3D _
    Inherits Geometry3D

Visual Basic (Usage)

Dim instance As MeshGeometry3D

public sealed class MeshGeometry3D : Geometry3D

Visual C++

public ref class MeshGeometry3D sealed : public Geometry3D

JScript

public final class MeshGeometry3D extends Geometry3D

XAML Object Element Usage

<MeshGeometry3D .../>

Remarks

MeshGeometry3D allows the developer to specify position, normal, and texture coordinate information. The Positions property is required.

Normals are assumed to be associated with the front faces of a mesh primitive. The winding order (the order in which the Positions that make up each triangle of the mesh are specified) determines whether a given face is front-facing or back-facing. Front-facing triangles are wound in counter-clockwise order; back-facing triangles are wound in clockwise order.

Examples

<GeometryModel3D>
  <GeometryModel3D.Geometry>
          <MeshGeometry3D 
              Positions="-1 -1 0  1 -1 0  -1 1 0  1 1 0"
              Normals="0 0 1  0 0 1  0 0 1  0 0 1"
              TextureCoordinates="0 1  1 1  0 0  1 0   "
              TriangleIndices="0 1 2  1 3 2" />
      </GeometryModel3D.Geometry>
      <GeometryModel3D.Material>
          <DiffuseMaterial>
              <DiffuseMaterial.Brush>
                  <SolidColorBrush Color="Cyan" Opacity="0.3"/>
              </DiffuseMaterial.Brush>
          </DiffuseMaterial>
      </GeometryModel3D.Material>
