Perspective effects
Basic 3D effect
The Basic 3D effect manipulates a clip in an imaginary three-dimensional space. You can rotate your image around
horizontal and vertical axes and move it toward or away from you. With Basic 3D, you can also create a specular
highlight to give the appearance of light reflecting off a rotated surface. The light source for the specular highlight is
always above, behind, and to the left of the viewer. Because the light comes from above, the image must be tilted
backward to see this reflection. Specular highlights enhance the realism of the three-dimensional appearance.
Basic 3D effect: Swivel (left), Swivel and Tilt (center), and Swivel, Tilt, and Distance (right)
The Basic 3D effect has the following settings:
Swivel
Controls horizontal rotation (rotation around a vertical axis). You can rotate past 90˚ to see the back side of
the image, which is the mirror image of the front.
Tilt
Controls vertical rotation (rotation around a horizontal axis).
Distance To Image
Specifies the image’s distance from the viewer. As the distance gets larger, the image recedes.
Specular Highlight
Adds a glint of light that reflects off the surface of the rotated image, as though an overhead light
were shining on the surface. When Draw Preview Wireframe is enabled, the specular highlight is indicated by a red
plus sign (+) if it is not visible on the clip (the center of the highlight does not intersect the clip) and a green plus sign
(+) if the highlight is visible. You must render a preview before the Specular Highlight effect becomes visible in the
Program Monitor.
Preview
Draws a wireframe outline of the three-dimensional image. Because manipulating an image in three-dimen-
sional space can be time-consuming, the wireframe renders quickly so you can manipulate the controls to get the
rotation you want. Deselect the Preview control when you finish manipulating the wireframe image to see your final
results.
Bevel Alpha effect
The Bevel Alpha effect adds a beveled edge and lights to the alpha boundaries of an image, often giving two-dimen-
sional elements a three-dimensional appearance. (If the clip has no alpha channel or its alpha channel is completely
opaque, the effect is applied to the edges of the clip.) The edge created in this effect is somewhat softer than that of
the Bevel Edges effect. This effect works well with text containing an alpha channel.
