Light Sample
The Light
sample demonstrates manipulation of light source array and manipulation of
properties of a light source.
The sample also demonstrates customization of
context menu and handling of its events.
Running the application
Number of lights edit box dynamically adds or removes light sources. Current
Light control allows selection of a source in the array of light sources for
display and modification.
Source type radio buttons allow changing between directional (infinitely
remote) source and a local one.
Direction/Location edit group displays coordinates of the light source or
direction where the light comes from.
Color dialog allows changing color of ambient and diffuse components of the
current light source.
Enable Prospective View check box gives choice between Orthographic (default)
and perspective view modes. In perspective mode objects, which are further from
the viewer appear smaller on the screen, which makes relatively sparse or large
scenes more realistic. See also IView2.Enable

synchronize this with the context menu the
application also disables the relevant options in the menu.
