CityScape 1.8: What would it be like on an interactive touch or gesture screen? (Video and link to demo)


Pixel Active, has announced version 1.8 of CityScape, "the rapid urban modeling tool that allows users to build both custom and real-world environments quickly and easily"


CityScape 1.8 looks ideal for use on an interactive touch/gesture display or table.  Since it allows people to work within the same environment concurrently,  I have a hunch that it might work, perhaps with a few tweaks, in multi-touch, multi-user situations.  

As you watch the video below, imagine your finger as the pointer, creating terrain, landforms, buildings, roads, and other structures and spaces, and editing on-the-fly.

The above video is of version 1.7. To learn about the new features, see the "What's New in CityScape 1.8" section of the Pixelactive website.

Unfortunately, it comes with a high price tag.  Even so, wouldn't it be a great tool to use in middle and high school classrooms?  I want to get the demo and try it out on a SMARTboard....I can think of quite a few ways that it could be put to work in learning environments.

About CityScape
"CityScape was created to reduce the tedious, labor intensive process of building and modifying urban environments, empowering the interactive world builders of tomorrow."


"Using robust data importing, rapid urban modeling, Active Adjustment features, and procedural modeling, CityScape is able to achieve substantial improvements in worker efficiency over traditional object modeling tools and scene editors.
Worlds created by CityScape are compatible with a variety of file formats and optimized for real-time rendering engines."

CityScape's client-server model allows collaboration between co-located or distributed teams so that the environment can be modified concurrently if needed.  It also lets users to check regions in and out in order to work on things independently.

Dynamic adjustment allows you to quickly change your mind and modify without headaches!
Buildings will keep their relative positions to the roads as roads are dynamically adjusted.


If you change elevations, everything will adapt automatically.

Haptics and Interactive Simulations

Following a link from Jonathan P San Diego, of London, I learned about Haptist, a user community for haptics researchers. The first thing I came across was "Simodont".

What is Simodont?


"Simodont is a high quality, high fidelity simulator allowing future dentists to be train in operative dental procedures in a realistic dedicated virtual environment while receiving haptic, visual, and audio sensory information".

"The haptics is based on the patented Moog admittance control paradigm. The use of a force sensor in the drill hand piece allows realistic rendering of drill and contact forces."

pdf info about admittance control and impedance control

Food for thought:
Jonathan posted this quote of Marvin Minsky on his website:

"It often does more harm than good to force definitions on things we don't understand. Besides, only in logic and mathematics do definitions ever capture concepts perfectly. The things we deal with in practical life are usually too complicated to be represented by neat, compact expressions. Especially when it comes to understanding minds, we still know so little that we can't be sure our ideas about psychology are even aimed in the right directions. In any case, one must not mistake defining things for knowing what they are."
