Hi, I want to focus on AI for my next project, but I am going to need to visualice lots of data to debug the AI, which needs to operate in 3D. Well, actually height is not very important for AI, but still have some relevance. So I would like to have a simple but scalable graphical engine(as it is going to visualice detailed information for one item but also to show the behaviour of hundreds/thousands AI animated items). No special needs, wireframe would be enough. It would be great if POV can be selected, to check if the perception part is working as expected, and zoom-in zoom-out capabilities, as well as text display with some interactivity for allowing different levels of detail. So graphic stuff is supposed to be there for helping with the AI process, as i don't want to spend time in creating it from scratch. Any recommendation to SDK/books/etc which can help? Thanks in advance

I dont know about an SDK... I use the Torque engine to develop my AI tookit, because I found it easy to use, its easy to start from the shooter example, and you'll find lots of ressources from other Torque Developpers.

Apart from that, the book AI Game Programming Wisdom has a nice article about debugging info for AI.
