Description
|
|
===========
|
|
The Lighting samples shows how to use D3D lights when rendering. It shows
|
|
the difference between the various types of lights (ambient, point,
|
|
directional, spot), how to configure these lights, and how to enable and
|
|
disable them.

User's Guide
|
|
============
|
|
The following keys are implemented. The dropdown menus can be used for the
|
|
same controls.
|
|
<Enter> Starts and stops the scene
|
|
<Space> Advances the scene by a small increment
|
|
<F2> Prompts user to select a new rendering device or display mode
|
|
<Alt+Enter> Toggles between fullscreen and windowed modes
|
|
<Esc> Exits the app.

Programming Notes
|
|
=================
|
|
D3D lights can be used to shade and color objects that are rendered. They
|
|
modify the color at each vertex of the primitives rendered while the lights
|
|
are active. Note that the walls and floor of this sample contain many
|
|
vertices, so the lighting is fairly detailed. If the vertices were only at
|
|
the corners of the walls and floor, the lighting effects would be much
|
|
rougher because of the reduced number of vertices. You can modify the m_m
|
|
and m_n member variables in this program to see how the vertex count affects
|
|
the lighting of the surfaces.
|
|
|
|
There are ways to generate lighting effects other than by using D3D lights.
|
|
Techniques like light mapping can create lighting effects that are not
|
|
limited to being computed only at each vertex. Vertex shaders can generate
|
|
more unusual, realistic, or customized lighting at each vertex. Pixel shaders
|
|
can perform lighting computation at each pixel of the polygons being rendered.
|

This sample makes use of common DirectX code (consisting of helper functions,
|
|
etc.) that is shared with other samples on the DirectX SDK. All common
|
|
headers and source code can be found in the following directory:
