Visualization and modeling with 3DS Max was a passion since max 2.5, specially modeling private products and items, then when worked in multimedia and designing field, I used Max to create better presentation for my clients products, and control the quality of product render and animation (if needed). At 20th started to use cad plans as a guide for modeling (mechanical parts and houses), under civil engineers supervision at first. Then I've combined my knowledge in programming (and old hobby which enriched by study and getting certified) to create interactive 3D application that can be used for educational purpose or games development. Finally, in 2010 I've started to learn using games engines like XNA (at first) then Unity 3D which is now my primary tools for interactive application development.
