Each entry in this collection represents a single triangle by referring to three points from the Positions collection. For better or worse, modern day graphics hardware and graphics programming is built on this core abstraction.Ĭontains a collection of all the points that define the mesh.ĭefines the triangles. Triangles are granular because other straight-edged shapes (squares, rectangles, and more complex polygons) can be broken down into a collection of triangles.
Arcs and curved surfaces are obviously more complex. Triangles are simple because every triangle is defined by just three points (the vertexes at the corner). That's because a triangle is the simplest, most granular way to define a surface. Computers prefer to build 3-D drawings out of triangles. As you've already learned, there's just one class that fills this purpose: MeshGeometr圓D.Ī MeshGeometr圓D object represents a mesh. To build a 3-D object, you need to start by building the geometry. If you want a cube, a cylinder, a torus, and so on, you'll need to build it yourself. In version 1.0, the WPF library lacks a collection of 3-D shape primitives.
The viewport can host any 3-D object that derives from Visual3D (from the System. Viewport3D derives from FrameworkElement, and so it can be placed anywhere you'd place a normal element. This container is the Viewport3D class, which is found in the namespace. If you want to work with 3-D content, you need a container that can host it. Rendering a 3-D drawing in WPF involves the following:Ī viewport, which is the host for your 3D contentĪ light source that illuminates part or all of your 3-D sceneĪ camera, which provides the vantage point from which you view the 3-D scene

This article covers the basics of 3D rendering and a few XAML and code snippets that is aimed at making your understanding better.

And any computer running Windows XP or Windows Vista can display the 3-D content, even when video card support is lacking.Įven though WPF's model for 3-D drawing is clear and consistent, creating rich 3-D interfaces is still difficult. Using WPF, you can build complex 3-D scenes out of simple markup.
