<h2>Keyframe Animation Panel</h2>

<p>The <strong>Keyframe Animation</strong> panel lets you create complex animations where you need precise camera control. Each keyframe that you set has nine <em>channels</em>, and each <em>channel</em> represents a part of the current view. For example, the <em>Field of View</em> (FOV) is a separate channel in each keyframe.
</p>

A thick vertical blue line marks the current position (frame) in the animation. The key time appears below this line in black. A light blue rectangle indicates selected channels for each keyframe. The key time for each keyframe appears below in light blue.
<br>
To change the current position (frame) in the animation, click or click and drag in the channels area. To change the position (time) of the selected keyframe, click and drag the key time. To select a keyframe(s) for deletion, middle-click the key time.

	</dl>
</dd>


<dt> <strong>Run and Save</strong></dt>
<dd>Runs the animation and saves each frame as an image. You must supply a file name prefix, frame start number, image type, and draw type. The image file name includes the file prefix, frame number and image type. For example, frame number 12 with a file prefix of FLY saved as a PPM would be named FLY0012.ppm. You can choose to render the animation off-screen (in memory). To render off-screen, you need to minimize the <strong>NVIZ</strong> viewer.

-<h3>NVIZ - Lights</h3>
-</A> <P>
+<h2>Lighting Panel</h2>
 
-The <A HREF="#LightP">Lights</A> panel contains adjustments and
-options to control the position, color and brightness of the lights
-and the reflectivity (shininess) of the surface.  There are actually
-two lights: one dim white light remains directly above the surface at
-all times and serves as fill light. The main light, which the user
-controls, is a "local" light which is positioned much like the view
-position.  When lights are being adjusted, a sphere appears on the
-surface and is continuously redrawn to show the effects of lighting
-changes.  The lighting adjustments do not affect the appearance of the
-surface until it is redrawn.  Neither light is directional; light is
-emitted equally in all directions.  <p>
+<p>The <strong>Lighting</strong> panel has options to control the position, color, and brightness of the lights. <strong>NVIZ</strong> uses a fill light and a main light. 
+The fill light is a permanent dim white light directly over the surface. The main light controls the shading, which you adjust using the <strong>Lighting</strong> panel. As you adjust the lighting, a lighting model (sphere) appears on the surface and continually shows the effects of the lighting changes.</p>

-<h3>NVIZ - Movement</h3>
-</A><p>
+<h2>Movement Panel</h2>
 
-<em>nviz</em></strong> starts up with one graphics window and one
-control panel window.  The top third of the control panel window
-contains the <a href="#MovementP"> Movement </a> panel.  Other panels
-may be selected from the <em>Panel</em></strong> menu at the top of
-the window. When a panel is selected it appears in the control panel
-window.  If the window is full, and there is no room for the new
-panel, one or more panels that are open on the control panel window
-will be closed to make room for the new panel.  Panels can also be
-closed using the <em>Close</em></strong> button that appears on each
-panel.  The <em>Movement panel</em>, however is always visible. Each
-panel from the <em>Panel</em></strong> menu will be described in more
-detail below.  <p>
+<p>The <strong>Movement</strong> panel always appears at the top of the <strong>Controls</strong> window. You use the <strong>Movement</strong> panel to set the position, direction, and perspective of the view. As you change movement options, a low resolution or wire grid of the surface redraws (<strong><em>fast display mode</em></strong>) showing the results of your changes.</p>
