javax.media.j3d.Alpha
The alpha NodeComponent object provides common methods for converting a time value into an alpha value (a value in the range 0 to 1). The Alpha object is effectively a function of time that generates alpha values in the range [0,1] when sampled: f(t) = [0,1]. A primary use of the Alpha object is to provide alpha values for Interpolator behaviors. The function f(t) and the characteristics of the Alpha object are determined by user-definable parameters:
Increasing Alpha parameters:
Decreasing Alpha parameters:
