Chapter 10 Using Spline Media
554
Extruding Spline Media
By default, objects are two dimensional. You can change the depth or thickness of an object
by extruding it. The extruded surface can use its own material. When you use the 3D
Extrusion shape to extrude a spline object or spline primitive, the Silhouette track replaces
the Face or Path track. It contains Transformations tracks that determine the appearance of
the spline’s faces such as Fill, Border and Animation.
Adding Color to the Faces
When you use the 3D Extrusion shape to extrude a spline object, Avid FX maintains the
Front Face color that you set, which you can change at anytime.
To add color to the faces:
1. Create a spline object using the 3D Plane shape.
2. Set the color to green.
3. Change the Shape type to 3D Extrusion.
A Silhouette track is created on the timeline.
When you extrude the track, the four faces are assigned the default Plastic material. The
green that you set remains assigned to the Front Face using Constant interpolation. The
other three faces (Extrusion, Bevel and Back) use the default gray color for the Plastic
material.
4. To use the color that you selected on all faces, set the Face Count menu to one.
Parameters Description

Invert Alpha option Select to invert the background’s original alpha channel. A
value of 255 (white) is transparent.
Size X, Size Y Adjust the size of the background track along the horizontal
and vertical axes.
Force Size option Sets the background size to the size of the project.
