#CONSTRUCT 3 3D HOW TO#
The code below shows how to create the same 3D scene in procedural code. The code below shows how to create a 3D scene in XAML. The camera specifies what part of the 3D scene is viewable.Ī mesh is created to specify the shape of 3D object (sheet of paper) using the Geometry property of GeometryModel3D.Ī material is specified to be displayed on the surface of the object (linear gradient in this sample) using the Material property of GeometryModel3D.Ī light is created to shine on the object using DirectionalLight. A Viewport3D along with the following components are used to create this simple 3D scene:Ī camera is created using a PerspectiveCamera. This example shows how to create a 3D object that looks like a flat sheet of paper which has been rotated.
