I need Xith-compatible equivalents to javax.media.j3d.PositionInterpolator and javax.media.j3d.Alpha. Are these already available? If not, I will write them.
None unfortunately. No interpolators at all. Please write one. A Spline interpolator would be nice 
???
import javax.vecmath.*;
Point3f point = new Point3f(0f, 0f, 0f);
Point3f point2 = new Point3f(-5f, 10f, 0f);
point.interpolate(point2);
I just can’t remember the exact function. But I’m pretty sure it does exist.
No Spline interpolator here, but it would be cool.
