Usage

To run the code sample

  1. Navigate to the solution file (*.sln), and double-click it. By default, the solution file is copied to the following folder:

    C:\Program Files\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Samples\CPP\Win32\Directx\d3dm\tutorials\Tut04_lights\tut04_lights.sln

    Microsoft Visual Studio 2005 launches and loads the solution.

  2. Build the solution (Ctrl+Shift+B).
  3. Deploy the solution (F5).

Remarks

The tut04_lights code sample is an extension of tut03_matrices.

To use lighting in Direct3D Mobile, you must create one or more "lights," setup a "material," and make sure the geometry contains "surface normals."

Lights can have position, color, and be of a certain type such as directional (light comes from one direction) or point (light comes from a specific x, y, z coordinate and radiates in all directions).

Materials describe the surface of the geometry — specifically, how it gets light (diffuse color, ambient color, etc.).

Surface normals are part of a vertex, and are needed for the Direct3D Mobile's internal lighting calculations.

Requirements

Pocket PC SDK: Windows Mobile 5.0 Pocket PC SDK.
Development Environment: Visual Studio 2005.
ActiveSync: Version 4.0.
