用的是OrthographicCamera，具体代码



<Grid x:Name="winForm" Width="484" Height="458" Margin="0,0,0,0">

        <Viewport3D Width="484" Height="458" Margin="0,0,0,0" MinWidth="483" ClipToBounds="True" RenderOptions.EdgeMode="Aliased">

            <Viewport3D.Camera>

                <!--<PerspectiveCamera Position="0,0,600" LookDirection="0 0 -1" NearPlaneDistance="100" ></PerspectiveCamera>-->

                <OrthographicCamera Position="0,0,500" Width="483" />

            </Viewport3D.Camera>

            

            <Viewport3D.Children>

                <ContainerUIElement3D>

                    <Viewport2DVisual3D Material="{StaticResource DiffuseMaterialStyle}">

                        <Viewport2DVisual3D.Geometry>

                            <MeshGeometry3D

                                Positions="-242 229 0  -242 -229 0  242 -229 0  242 229 0"

                                TriangleIndices="0 1 2  0 2 3"

                                TextureCoordinates="0 0  0 1  1 1  1 0"/>

                        </Viewport2DVisual3D.Geometry>

                        <Viewport2DVisual3D.Visual>

                            <wl:LoginPanel Width="483" Height="458"/>

                        </Viewport2DVisual3D.Visual>

                    </Viewport2DVisual3D>

                    <!-- 三维变换 -->

                    <ContainerUIElement3D.Transform>

                        <RotateTransform3D CenterX="0.5" CenterY="0.5" CenterZ="0.5">

                            <RotateTransform3D.Rotation>

                                <AxisAngleRotation3D x:Name="axr" Angle="0" Axis="0 1 0"/>

                            </RotateTransform3D.Rotation>

                        </RotateTransform3D>

                    </ContainerUIElement3D.Transform>

                </ContainerUIElement3D>

                <ModelVisual3D>

                    <ModelVisual3D.Content>

                        <DirectionalLight Color="#00FFFFFF" />

                    </ModelVisual3D.Content>

                </ModelVisual3D>

            </Viewport3D.Children>

        </Viewport3D>

    </Grid>
