You can easily create 3D digital art of your own if you have the determination, the drive to actually do it, and some spare funds to buy the programs. Also you will need enough memory and processing power to create and store your soon-to-be-expanding museum of work. Most up-to-date computers have the capacity.
Some of the best programs available for 3D digital art include programs for figure modeling and environment creation that allow you to create virtual worlds and inhabit them with people and creatures of your own design. Many of these programs are used by major motion picture companies in their visual effects departments.
When it comes to recommending programs, everyone has their personal favorites. People will argue for days about which programs do what best and where someone elses picks fall short. With that said, Lightwave, Maya, and World Builder are some of the best. Good cheaper programs are Poser, Adobe Illustrator (actually not so cheap) and Corel Painter.
Learning to Make 3D Digital Art
Making 3D digital art might be frustrating at first if you do not have much experience, either with computers or with creating art. The key to making digital art is just to do it. Think about you work as what it is and not what it should be. Some programs are harder to learn than others, but if you do not keep at it, you will never learn.
