GlExtrusion

public GlExtrusion(float[][] spine,
                   float[][] crossSection,
                   float[][] color,
                   float[][] orientation,
                   float[][] scale,
                   boolean beginCap,
                   boolean endCap,
                   boolean ccw,
                   float creaseAngle)

Primary Constructor.

Parameters:

spine - [spineIndex] [x,y,z].

crossSection - [index] [x,y].

color - [spineIndex] [r,g,b].

orientation - [spineIndex] [angle,x,y,z] to provide a "twist".

scale - [spineIndex] [x,y].

beginCap - draw it or not.

endCap - draw it or not.

ccw - counter clock-wise polygon ordering (TBD).

creaseAngle - smooth VS facet normal cut-off (TBD).

Throws:

java.lang.NullPointerException - if an argument is null.

java.lang.IllegalArgumentException - if an argument is invalid.
