I graduated from college with a degree in math-computer science and have been working in the subd/cad industry for 1 year. My company attends siggraph every year and after going this year, I was fascinated by a demonstration that created a creature using zbrush. Seeing the demo made me want to dabble in the field of 3d design for games.
I've looked around this Q&A site and looked around some of the job opportunities as a graphics person in indeed/monster and came to the conclusion that a BA or MA from an arts academy is probably not required. However I have no training, and am not particularly artsy. So my question is:
1) What is a good way to see if I have a passion for this field? I am very interested in the field right now but I'm not sure if I am willing to do this for a living yet. Are getting certificates a good way to see if I enjoy this field?
2) Out of the many 3d modeling programs out there, which ones are used heavily in the industry?
