Wick3d is a 3D engine in progress for Actionscript 3. The project started as a playground experiment for the author to learn from during development, and as such it is in no way meant to be used for professional or commercial projects. Use Away3D, Papervision3D, or Sandy3D in such a case. Wick3d is offered as open source for anyone with an interest in 3D maths to look at, give feedback in the form ideas or remarks, or - who knows - learn a thing or two as well.
