Here is one of my favorite architectual renderings.
I had the idea and I acomplished it by going to the stadium and watching the games and using photos that my dad took of the stadium when he worked as an electician when the ball park was built, (Happy Father's Day Dad). I also used a wallet size schedule seating chart to make it as close as possible to the actual dimentions. I used AutoCAD to model this and the old VIZ Render to render it. I also have more camera angles and a cool 180 degree animation. If your wondering what I used to texture it, I used PaintShop Pro because I did not have Photoshop or Maya yet. Ohh and it took about 4 to 5 weeks. Refrence photos are availible by request.
