best 3d app on the market?
- depends what you want to do exactly. movies, games, comercials, web, print, etc they all have different features and are all designed for different purposes. so theres no one that is "best". The best one is one that most suits your needs.
easiest learning curve?
- i have used pretty much all of them out there, i found lightwave to be the easiest to use and learn.
advantages/disadvantages of each?
- like i said depends on what you want to do, its not really advantages/disadvantages its more what each program was designed to do.
documentation
- you will find most of the major apps have good documentation and the web has a world of information, tutorials and resources available.
cheapest
- there are some free ones around like blender. but if you want a really good app you will have to pay good money for them.
in terms of which one is best, really depents on the person using it. i have seen great works from artists using all the different apps and even people producing better work on the cheap apps compared to the highend stuff. so it all depends on the artis and how they make use of the software.
the ones i would suggest as entry level or mid level are these:
lightwave (recommended)
3d max
cinema4d
these 3 are well priced, have great support and will allow you to produce just about anything you want.
have a look at their websites and judge for yourself.
i choose lightwave for its ease of use, great rendering and modelling and i think its the designers 3d app. the others a slightly more technically orientated. (and i started using it on the amiga

)
